Hello all:

Just got my Supersprint Street mufflers and X-pipe installed on my 2006 Z4M Coupe. The system went together very easily, installation took about 2 hours (moving slowly), and it fits as well as any factory exhaust we have ever worked on. My shop has installed literally hundreds of aftermarket exhaust systems that are supposed to be "bolt-on", but very, very rarely does an exhaust system literally bolt on as easily and hassle free as did this one.

The sound is absolutely amazing. It is maybe 5% louder than stock, but much, much deeper. The guys at Supersprint say this is about a 8-9 HP increase, but the butt dyno shows a whole lot more. I am absolutely and totally satisfied with the sound of the system; I find it is more difficult to choose an exhaust system than a set of wheels, or any other upgrade for that matter, as if it drones, or is too loud, you will have wasted a good chunk of change. This system has a nice mellow sound, not raspy, sharp, or too loud that it drones. It sounds fantastic!!!

ENJOY!

Very cool! Would you know if you're reducing the weight or is it being maintained?

Very cool! Would you know if you're reducing the weight or is it being maintained?

The weight is more or less the same, with a slight advantage going to the Supersprint system. While I didn't weight the parts with a scale, I would estimate about 5 to 6 pounds lighter per can, and about 10 pounds lighter for the X-pipe. Surprisingly, the factory parts are quite light. I was pretty surprised, because my E46 M3's factory exhaust easily weighs 2-3 as much as any other decent exhaust system out there...possibly made out of lead, who knows???

Where did you get it? Looks well made...not surprising for SS.

Does anyone know if I can just bolt on the muffler section of the exhaust?

I love those tips compared to the stock tips (too weak looking)

:drool: do it chris

Yep. No problem.

Fatlip-Where did you get your supersprint system? Price?

well that's my first post here, but been checking out the forums for a long time :-)

now that you've posted your new set up, it means you gotta post a video or at least a sound clip!

Wow, I can't beleive that people take a brand new car and spend 3 grand putting in a new exhaust. The other one is brand new too, could 5 hp be worth that much? Why not wait until the other one is used for at least 50k miles? What about your warranty?

i understand your point sort of but when u buy a 60K+ car (out the door cost with options, etc.) another 2 or 5K is not that much to get the exact spec that u want. some drivers want the exact sound, tire, wheels, brakes, looks, etc that is not afforded by the stock unit. and for some people a few more hp's IS really critical especially if you are a regular track driver. that would'nt be me mind you, don't have too much of a discretionary spending budget myself, but that's how it goes. and if you're gonna mod the car, the best time is to get it out of the way when it's new.

seems you're the average car enthusiast :-P and not a hardcore fanatic like us haha j/k :-)

anyways i think i would drive it stock for maybe 1 year or 10k miles or so before i think about changing the exhaust.. for me it's more about the sound not the hp :-D

It might be brand new but it is crap! When my brother was driving by me in his M Coupe while I was in my friends 540i I couldn't even hear the car at all! It was wisper quite. To me a sports car needs to sound like a sports car and not to mention those exhausts are down right ugly! They are already rusting and the car is not even 3 weeks old! So I think next week we are going to take them off and paint the exhaust cans black as a stop gap measure. Now the only question is SuperSprint or Eisenmann? I was know my brother is going to go Eisenmann but I think I might try out the SuperSprint this time around!

I don't know exactly how the m coupe will sound but I drive by sound more then by gauges. A car that is too quiet isn't easy for me to drive properly (example: heel toe rev matching) so a good sounding exhaust makes a big difference.

This thread is worthless without sound clips

I drive by sound too and the M Coupe is plenty loud enough from the engine to do good heel-toe work.
I don't care what it sounds like to other people just so long as I can hear what I need to!

Soundsclips coming Monday...just got a new camera, should get the job done nicely.
it's tuesday.. wanna hear that beast!

He must be too busy out running it through the gears, that what I would be doing at least

Will this system pass emissions testing in North Carolina? I'd hate to have to change to the factory system once a year for one day to pass emissions testing.

Yes, it is a cat back system and has NO effect on emissions.

ever get to those sound clips or vids???

wanna hear a good rev, and def it run through some gears

Sound clip?

Need a sound clip!!!!! Its monday 27th!!!!

Please Sir, can I have a sound clip?:( :( :( :( :( :( . I promise to be good.:D

I have it on my car. Anyone in San Diego area that can take sound clips and post them for me?? I am willing to drive up to Orange county to help the board out.

Where did you get it? Looks well made...not surprising for SS.

actually supersprint is known as supershit on some of the other boards because the welds were done very poorly on many systems. hangers have broken off and holes have formed.

Sound clip anyone?

Please someone help him out! I really want to be able to hear what this sounds like before I decide to purchase!

Hell, this guys in Atlanta. Its only a 5 1/2 hour drive for me. I'd go down to hear it if I weren't such a tight bastard.

Bump,
no?

Fatlip,
Bring your car to Road Atlanta tomorrow and Ill take some samples of your exhaust. Ill be there from 8am-3-4pm.

Please follow links for two quickie sounds clips of the Supersprint Street mufflers and midpipe. Thanks for the patience all, I know I promised these weeks ago, but I forgot all about this thread until today.

I can post some pics clips from inside the cabin, but that will have to wait until tomorrow, or as I like to call it, February.

Enjoy...

So wait ... you have the street version and think it is too loud?

Thanks Craig! How many miles do you have on the exhaust now? Has it changed since it was new? I need to come down and check it in person.

Too bad about all the blue smoke! (just kidding)

No, not too loud at all. The sound is perfect. It sounds a little less "hollow" lately, but overall, it didn't make much of a difference to the sound level. I have approximately 1200 miles on it now, so I don't think it is going to change at all from now.

Come on down, just check with me which store I'll be hanging out in, Doraville or Alpharetta.

I have 3000 miles on my exhaust and it sounds pretty good. It did change a little bit.

I'm torn between the street version and the race version... a buddy of mine has the race version on his M3 and it sounds pretty sweet, but I'm worried that the lack of roof may make it a tad bit loud due to lack of insultation between me and the open exhaust.

Get Sport and the SS X pipe. It will sound perfect.

Sounds great! I think I'm going to get the supersprint system, are there any others I should consider? Supersprint is being described as what I am looking for... deeper sound with a small increase in volume over stock. It didn't sound like it in the video, but is there any rasp? or drone while cruising on the freeway?
thanks for the clips!

Installing a performance exhaust in no way shape or form voids any kind of factory warranty. And 5hp, increased throttle response, and improved fuel mileage are all reasons that make it worth the extra $$$. I'd go one further and install new headers and cats...or maybe no cats.:evil2

I would never NOT install cats on an S54. The engine works better with cats then without.

Headers and aftermarket cats also costs about $5k when you are done with software and that is not worth it IMO.

:confused

little contradiction there...

I had a chance to check out Fatlip's exhaust today and take a short drive in it. It looks really nice and sounds just a hint louder than stock. It's a good, deep sound and could very much be considered for daily driving. The quality (yeah I got on the cold ground) looks top notch as well. No sound samples but imagine your car, just a bit louder at open throttle.

Interesting assessment... how do the tips look next to the diffuser?

They are a little larger than stock but no where near honda coke can sized. I took this photo from a different angle.

Those tips sure do look nice... I just got off the phone with the guys from BMPD and they said there is a significant price difference ($200+ per side) between the street and race versions because the street version has more tubing inside the muffler to keep it quieter. However, the difference in sound levels between the street and race is only 4-5 dB from their claims. They also said there is a minimal power difference between the two... it's mostly just a sound difference.

The middle x-pipe helps to make the sound deeper... not necessarily louder they say.

I personally have not heard the race, but can only speculate that there is a significant difference in the sound level between street and race, as if there wasn't, people would continually question which version they had installed. I don't believe Supersprint would build two versions if there wasn't a significant difference between the two. That being said, if my current street system was 10% louder, I would consider it too loud. Right now, it sounds as it should have sounded when the car came from BMW, which is exactly what I was going for. Any louder, and it would be boomy and resonate in the cabin.

I'll post more clips as soon as I get over my recent back injury...

Great... I hope you get better soon. Part of me is very tempted to fly up to Atlanta, GA to hear it because I'm so torn between. Turner Motorsports told me today that the 'sport' muffler is the same loudness as the stock system ... which didn't make sense because the stock system makes no sound at all.

Do it. I got the first round. :D

sweet exhaust

Can you substantiate your statement?

Hi,

can you post more pics, please?

Maybe from behind..

Would be great, thanks.

Bump, any more word on how the exhaust sounds?
I'm quite interesting in an aftermarket pipe system.

What else besides Supersprint is out there? And where can I buy the Eisenmann system?

Thanks.

Here's a couple of mine....
This the sport system with 80mm tips.
Sound is OEM + 10% - but deeper & richer. (sorry no sound bites)

bahhhhh wanna get this so bad...just sittin and waitin for that tax return!!!

inTgr8r, cans only, or did you opt for the x-pipe too?

Yes, X-pipe too.
Absolutely love this system.

If the weather ever gets a little warmer here I'll work on getting a sound clip.

yea def get that clip... ive only heard one with the supersprint, and it was short

Another question: Will this void warranty on the entire car or just on the OEM exhaust system?

Another question: Will this void warranty on the entire car or just on the OEM exhaust system?
The only warranty that is void is the part you changed and any part affected by the part you changed.

Sounds Clips Please :)

I thought that's how it works.

Thanks :-)

I'am right now talking with Sami from AA about a TS set up on my Z. And I looked into super sprint and they came back to me with 5200 bucks for a complete set up.

So me having common sense and that figure being insane. I did the next best thing, Getting AA headers taking out all the cats and straight piping it into the stock exhaust or just straight pipes got to see if straight pipe is just too loud. AA say's there software will remove any cells I will get due to it.

And to the OP that set up looks great, but I just don't have that kind of money for a set up like that. Great stuff.

Removing cat(s) usually makes for an aweful sound. I don't have experience with this motor but in the past I ran my Elise with no cat and it was much too loud. Even on track you could hear me a mile away. Although, the flames looked cool. :)

Are you planning on driving your car on the street with this setup?

Here's a short vid with no cat:
http://video.google.com/videoplay?docid=-6125694294067396692

I ran my M3 with no cats ... it was crazy loud. Some people like that. That being said, My M Roadster and M3 sound nothing alike and being that I don't have a roof to help isolate me from the sound now, I'm probably leaning towards just the SS Street mufflers intead of the Race mufflers.

i dont think ive heard an e46 with no cats...did u ever take clips?? i am curious

That is probably the street loudest car I've ever heard :eek:

I will look and see if I still have them... I was running headers, no cats... stock middle pipes with resonators and a AA Exhaust. It was loud... very very loud.

i like loud...as long as it still sounds good

It was very race car sounding... at full throttle or high RPMS, it sounded well like a race car. At low RPMs are cruising, well... it was alright. It sounded like a race motor being put-put around the street... not ideal, but the price you paid for that racing sound at full throttle.

That being said ... the Roadster doesn't sound anything like the M3 did in stock form.

I test drove a new Lotus Exige S yesterday. The car gave me a headache after 30 min.

Definitely a weekend car :)

That being said ... the Roadster doesn't sound anything like the M3 did in stock form.

i hope you mean that as....the roadster sounds BETTER, right?

this is the normal Z4 one... by bmw supposedly

dunno if we could like "cut out" the other hole??? i dont know the properties of cf that well
