OK,

I'm beginning to personalize my 01 740i and I can't believe that exhaust system. Behind the cats is that weird looking pancake resonator thing flowing into dual fatboy muffler pods....that are just begging to be eliminated.

Does anybody make a catback exhaust for the E38?

My concept, if I can't find a bolt on (or close to it) system is to cut the exhaust between 02 sensor and the pancake thing....then add two 4" high flow tube mufflers in place of the pancake and custom bend some tubes just short of the bumper. I don't want to cut the bumper cover so I'll just add some down facing tips just inside the bumper cover. Sounds simple eh? I'll probably lose about 50lbs and gain some TQ.

Has anybody done this before? If so, how did it turn out. What size tubing did you use, and Pics would be great!

Thanks

yes!! im on the same track. Im going with an x pipe at the mid muffler and i think hiflow mufflers axel back.

Have you looked at these...

That's what I had fitted to my 740 - and it's excellent :buttrock

Talyon:
I was also thinking about an X pipe in the middle. What kind of mufflers do you plan on using? What size pipe?


Scorcher:
Your car is a cool color.
On the exhaust, did you use their headers or just the mufflers?
Do you have a picture of the underside of your car?

I checked the Dinan site and they have a system for $3700......I think I can do mine for 15% of that, installed....theirs must come with special ceramic coated stainless steel headers.

Definately an x-pipe if your gonna mess with the resonator, Magnaflow 14815's, then remove the resonator if you want it louder. If it's too loud, put some aftermarkete resonators in and call it a day. Unless your going FI'd, there is no reason to spend upwards of 2-3k on an exhaust that is only gonna change the sound. Start at the mufflers and work your way forward.

im about to purchase 2 of the magnaflow 14816's and just have them put on...will it make much of a sound difference? what else could i do to give it a nice sound but without spending 2k.

816's are what I meant, my bad. Adding those cans alone will make a sound difference, but if you want MAKE SURE you do an x pipe first......then either delete the resonator all together, and if that's too loud add some aftermarket resonators after the x-pipe install to get a happy medium between louder than stock vs. WAY louder than stock w/ a drone. Do you follow me. Basically, this order, from quitest to loudest/droney

Stock
Install dual 14816
Install x pipe and delete stock resonator for aftermarket ones
Install x pipe and delete stock resonator and stop there

I've even seen a local M5 owner who instead of installing new mufflers just deleted the stock ones and ran straight pipes from the resonator. I think it would be fairly louder than adding just new mufflers, but make sure to keep the resonator.

Its just my preference, but I don't want to cut the bumper cover to accomodate the tips or hang them under the bumper.

My strategy is to replace the resonator thing (and its pretty big) with two round Magnaflows like a 12619 then straight pipe to the rear. The tip be turned down behind the bumper so nothing would be visible. I just need to decide on the pipe diameter..........should give a nice tone and cost less than $500 installed (famous last words).

where can i find a good x pipe? are the ones magnaflow sells ok?

im putting on new converters so i think i should add resistors and x pipes but where can i purchase them ? thanks

bump thisssssss its a good topic haha

where can i find a good x pipe? are the ones magnaflow sells ok?

Well Britalman makes a really nicely bent x-pipe for the m5 kit, but i"m sure just about any local muffler shop has a generic x-pipe which will get the job done for ust about anyone except for the descrminating guy who wants that extra 1/5 hp.

im putting on new converters so i think i should add resistors and x pipes but where can i purchase them ? thanks

Any local muffler shop

if i get the mufflers welded on first would it be a pain to go back after and get the x pipes done or is it better to do it all at once???

I am assuming you are talking about replacing the resonator with X-pipes. If that is the case it's more cost effective to do it all at once. If you remove the resonator, you can have the muffler guy weld in the X-Pipe and bend stainless back to the new mufflers.....and you lose that funky pancake thing.

If you do it in phases, the mufflers would be attached to non-stainless piping and would have to be cut off and re-welded when you did the phase 2. I think it would work fine and phasing is a very sane approach, but would cost a tad or few more.

Are you going to route through or under the bumper cover? Or bend em down?

Here are links to my exhaust build out. I went through several cat/resonator/muffler combos before I found the right tone, quietness in the cabin and performance.

bear your car has the sound i want that MEAN MEAN MEAN sounding growl. hahah its SICK but my budget for exhaust is gonna be around 450 and the magnaflow 14816s are 214 for both shipped and install is 50 but i cant really change the cats because of californias strict laws. so what do you recommend?? im only 17 so i dont really know much about the other parts of the exhaust system loll so please help me out thanks

I think magnaflows are pretty popular but Eisenman ftw

if i had the money for SURE id put them on but they are like 1200 bux

Farhod,

Let me understand this........after looking at your sig.......you spend what $8K? in A/V media mods and NOW you're on a budget?

Forget the exhaust, you could have straight pipes and you wouldn't be able to hear it over the Kickers anyway.

You were how old? 17? How about some Lambo doors? So the 16 year old high school chicks could slide right in, and Limo tint so nobody can see what you're doing. Now that's money wisely spent.


For the guy who posted the older links.....the PICs don't work.

umm im not sure if that was supposed to be an insult or what.... but actually i spent about 3500 on audio and video mods and thats what i had saved up but now thats all gone so yes NOW im on a budget. Just because i have subs in my car means i cant hear my exhaust???????????? hmmmm

Yes i think i did say i was 17...just because im 17 means i have to put lambo doors?? I drive a 740 not a honda civic i think ill let go of lambo doors and i already do have limo tint...... not sure if your trying to be funny but let me tell you dont quit your day job. not sure why your trying to flame me for asking a simple question

I recommend, with that minimal budget, that you don;t do your exhaust. You'll need about $1,500-$2,000 to do it right. You could skip the REMUS and go with a magnaflow high-perf stainless and save a few hundred, but everything else is mandatory.

For the guy who posted the older links.....the PICs don't work. "the PICS don't work" Is that a technical assessment, like "the brakes don;t work"? I think the place where the pics were hosted most likely deleted them, since I haven;t used that site in so long. If anyone is intersted in the pics, I believe I have them on my home computer and could send them via email. LMK

Bear:
The Pics would not display on the link you provided. You can email them to Tracquest@yahoo.com.

Farhod:
My comments weren't meant to be an insult...sorry for the sarcastic tone. When I was 17, I spent ALOT of money and time on my cars too, as I contracted "Mad Car Disease" early in life.

The performance gains you get from upgrading the exhaust is minimal, but I'm doing mine for the tone as well. Mine should be done later next week and since you live in Corona you're more than welcome to come check it out. Pics are one thing but exhaust needs to be heard.

BTW, I really think lambo doors would look cool. They never work very well, but they look cool.

And.....I have 2 12" Kickers in my suburban. With the amp gain at 2/10ths and the remote bass control turned way down they bump so hard it vibrates my entire vehicle. With 3 in the back of a 740 your trunk lid has to be in constant motion.

if you cant afford the good stuff then dont get the cheap stuff and trash up your ride

i will get lambos one day on my 7

Just some video from when my old 95 740i came back from my indy with the M62 swap and upgraded exhaust. The video in the beginning is with 2.5" pipes from the headers to high flow cats to glasspacks to straight pipes out the back. The later videos have my upgraded dual 3.5" dual tips after the glasspacks. The highway footage on was taken today on my morning commute and I had my buddy at work pilot her while I shot video.

I am assuming you are talking about replacing the resonator with X-pipes.

Yes, or maybe even slide the x-pipe back further, then just incase it's too loud you'll still have room to install aftermarket resonators

what do you mean by old 740i you actually got rid of that ??

Any chance you can just write a quick summary. I've basically got the idea of going with an x-pipe, then aftermarket resonators, then 14816's still.....what did you find as errors and/or not like about the Magnaflow cans, or do you think you missed any steps like what I am considering above?

Growl on the highway sounds great, but that popping noise sitting in the driveway just sounds bad bro. You've got stock gears right? I can't wait for my 3.64 to get installed, i'm sick of my motor making all that noise and only moving slowly off the line.

Yeah, Sold it to buy the Blk/Blk 99 740i I drive now.

I like the old school muscle cars so I kind of like the crackling and popping. Bystanders loved it, always thought I had a worked LS1 swap. Looking fwd to seeing your mods come to fruition. :)

Very nice video......love the sound on the "drive by" shots.

First, I would like appologize, to all the honorable members of this forum and thread for going off topic, but I absolutely must take advantage of this opportunity.
Justin, glad to see you are still alive. Apparently, you had enough money to upgrade to an M62 engine and then a '99 E38. Just wondering if you had about $1200 left over and if so, might consider returning it to ME since that's about what you still owe me for parts not delivered for my M7 project (rear diffuser,fogs, rear spoiler). Frankly, man, you have a lot of b.....ls showin' you mug (avatar) around this neighborhood after what you did to the fine people of this community.
Why don't you do all of us a favor: Take all the money you stole from us; Crawl back into your little hidout hole with all the parts for your dream E38 (which I'm sure WE bought) and all the receipts of what I'm sure is an incredibly successfull real estate business and leave the rest of us alone. IMO, your input and comments are not welcome and have no value here.
Again, sorry for the rant off topic to all the other members, but this guy should'nt even be allowed to walk the streets let alone post on this board.

Terry,

Not trying to hijack the post. PM me your number an lets get this worked out. I have been a member of the 7 community for 12 years and I am here to stay. I want no bad blood. I just want to do the right thing, got caught up in some bad business dealings. Just FYI engine swap was on credit. Others have been paid back or are in the process of being paid so I would appreciate you not classifying me as a theif. I could have went the way of HIDS4LESS and stiffed everyone, but I didnt, yeah I have caught hell but I have and will square anyone who has got caught in my business crossfire.

I'm curious. You say you've been a member of the 7 community for 12 years yet your join date is 05/02. My math is not that bad. Is this a mistake or just more BS?

There was life before BF. RF started it all. I started hanging around the 7 community in 94 in RF's infancy. :rolleyes No threadjacks or flamewars please. If someone has a beef lets start another thread or PM me. I believe the subject at hand is E38 exhaust......


Also FYI (http://bimmerboard.com/forums/posts/285957): And for the record I settled with Joe aka Bimmerfreak who had the threads here to. I am not BS'ing anyone.

so just popping on 2 magnaflow 14816s aren't gonna make it sound good enough?

Are these the right ones:

wow those look straight im not sure if there the right ones either but they look okay.

You wont like it - get in touch with me -i've done it all 485 hp all.

there is a lot to consider if u want to do it right

there is a lot to consider if u want to do it right

how do you do it?

exhaust or not to exhaust - just a few words on exhaust. the 740 is a performance exhaust can handle more hp than you think - Dinan exhaust gives you a 10 -12 hp gain unless you upgrade -coldair , throttle then you get maybe max 16 hp. if you are looking to spend $$$ go eisenmann- keep the stock resonators. Stock exhaust is around 2" (its a metric size) u dont need anything bigger than 2 to 2-1/4" depend on the sound u want. Bigger pipes - more resonance, throtter sound. The magna flow way with x pipe, resonater and flow thru exhaust has a particuler resonance at 1800 to 2000 rpm that bothers me. Keeping the stk resonator tones this down considerly and delivers same hp rating. If your feeling that the 7 is getting sluggish get your service guy to do a back pressure flow reading - 1 before pre cats - 2 after pre cats and the same with main cats. This will determine if you need new cats. Another alternative is to gut to stk mufflers and have new tail pipes installed - a good exhaust guy can do it inexpensively & it sounds good.
i'm currently running with modified frt cats, thru magna flow hi-flow cats ( had x pipe with resonator set-up - took it off in favour of stk resonator = i can sell it to you if you want $400.00 cdn) all 2-1/2 stainless (mated down slightly to stk resonator) and flow thru magna flow mufflers. i run 460 + hp and the there was little to no difference removing the x pipe. Next year i'll probably go to to eisenmann but remus is a strong second as i am a dealer for them and can get them at a good price. So why the magna flow? my friend installed them for me, he is a magna flow dealer and he swears by them. As for me i just swear!

U can go to www.e38.org (http://www.e38.org/) sift thru the posting for exhausts. Good info.
