I'd like to bring the Eisenmann stainless steel units to the BMW 7-series E38 owners. This exhaust is stainless steel, produced over seas in Germany, & the tip size of the product is 83mm.

Two versions of the exhaust are available. The Sport & Race versions. To differentiate btwn. the two units the Sport exhaust is a less quiet compared to the Sport exhaust, but has a great nice clean tone to it.

The Race exhaust, on the other hand, has a more deeper & aggressive tone output. Both exhausts, need to be properly broken in, to maximize performance, as well as sound.

Properly broken in? New engine, new brake pads, new clutch - break in period I understand. How does one break in an exhaust?

if the mufflers have a stuffing (as many do), the sound can slightly change after the first few weeks. im not sure why, but ive witnessed it.

most people do not notice the change because the exhaust is new to them already and they just think they are getting used to the sound.

When you first install the exhaust into the vehicle, the full potential sound won't be heard, until you drive it for a wk or so. Initially, you'll notice the sound becoming more agressive/deeper as time progresses.

This is common with the Eisenmann exhausts. That's what I meant, when the exhaust needs to driven for a wk, until the full potential sound is properly heard. :)

Very happy with mine! See more info on my Car Domain page. Lots of info if you search under Eisenmann on this forum.

Did you purchase the Race or the Sport unit?

OK, so it's not like you drive the car hard or soft for X miles, you just use it for a week or so. First I'd ever heard of that, thanks.

I got the sport. Both times! I'm actually on my second set. My car was rear ended (again) about a year after I had the first set installed and the exhaust system had to be replaced.

They have a really nice tone, but it is not that much louder than the stock system. I considered going with the race version the second time around, but I was concerned that it might be too loud and preferred not to bet and get something that was too loud.

Note that the same exhaust system on a V8 is much louder and has more rumble. A lot more like an American 60's or 70s muscle car. It has to do with the way that the exhaust pulses stack up or cancel each other with the different timing.

You should be able to dig up some information if you do a search.

i paid approx $1400shipped for mine. wish i could have heard Dave Clement's car at last year's bimmerfest. by the time i met Dave, i was tired, sweaty and ready to go home =(

Dave is right about the V8 being rumbly and muscle car sounding. i keep trying to convince myself that the car has a nice, bavarian growl down low and a low-strung ferrari sound up top, but this isn't actually the case *grins* the car sounds downright mean down low...burbles a lot. past 4500RPM, i think the sound is great. many others who have heard my car in action (from the outside) agree.

when i was buying the exhaust, there were 3 versions: sport, high performance and race. i went with high performance. i have no regrets. given how loud my car is now, i shudder to think how insanely loud it would've been with the race version.

took about 500 miles for my exhaust to sound the way it does now. namely, it wasn't loud at all at first but got significantly louder after ~500 miles of use.

Sometimes I feel like an idiot. But, you won't know if you don't ask.

1, What do the measurements refer too, and why does one choice have 2 and the other have 3?

2, I want to maintain the stock "sleeper" appearance. Can the tips be modified (changed with one's that bend down) so I can keep the stock valance.

I would love to have a more aggresive sound but i like the fact that you cant see the exhaust tips oem. I actually think it would look really cool to have the exhaust tips barely visible turning down behind the bumper valence. I really like the nice clean lines of the bumper valence unaltered. Do you offer tips for the exhaust that retain the stock appearance or perhaps ones that show slightly on a "turned down" aspect? Also, anyone from the Cleveland area have this exhaust? I would love to give it a listen. Stu

The numbers indicate the size of the tips, for instance 4x83mm means there are 4 tips with the size of 83mm. If there are 3 numbers, usually indicates that the tips are oval. So the 1st number indicates how many tips, 2nd number indicates diameter, & 3rd indicated the size of the tips measuring it horizontally.

2) If you want to maintain a sleeper, we can *try* to get you the old style tips, which don't say Eisenmann on them - however that is the most we can do at this time. :)

Any muffler shop could modify them. They'd have to butcher the tips and weld turn-down's on. Seems like a shame for such a nice exhaust system though. You could just have a custom one built for much cheaper if it's going to be hidden.

Bread,

I really am just looking for a hp gain (performance in gereral). Because of that and wanting to keep the car looking stock, a custom exhaust is the way to go? Much cheaper you think?

Oh hell yea. I'd only get the Eisenmann if you like the tips and want it to be mounted as designed. Otherwise, have one built from scratch.

I had a full true dual system put on my truck from the headers back for $480. All custom bends as no aftermarket system is available for International trucks. All of these aftermarket BMW exausts (Remus, Eisenmann, etc) are from the rear wheel back. So it's much less complicated (read: cheaper) to put together. Especially if you just want a couple dump tips welded on which doesn't require any modification to the rear skirt.

There are tons of options that sound great with a V-8 Depending on the sound you want. Flowmaster has three stages of performance/sound to choose from. I have a set of 40 series on my truck, but they are very throaty. I'd recommend the 60 or the 80 series for a BMW. Dynomax mufflers sound really nice too. And I had an Edlebrock muffler for years that I got tons of compliments on. So if I were you I'd just go hit up a couple muffler shops and see what they have to offer. It's not uncommon for them to temporarily mount a few of them up so you can hear the differences as well. You'll have to ask.

I need new exhaust for my E32. Is there a version avaiable for one? Is it similarly priced? Also is the system from the cat back or can I get one from the manifold to the rear tire?

That's amazing that you had one custom built at that price, and it was successful! I really appreciate your maturity on the topic & choosing alternative routes for exhaust.

It's just amazing how people will bash people for having a "custom exhaust." They think it's more inferior to products such as Eisenmann, Dinan, AC Schnitzer, etc etc...

Don't know about the E32 version, but the E38 units start after the y-pipe between the rear wheels and DO NOT go all the way up to the cats. These systems are pretty much just a couple mufflers with a few feet of pipe to connect to the stock exaust.

Rob Levinson at UUC has a full system from the exaust manifold back for the E38. But I don't believe it's available to purchase yet.

I think the Eisnemann rocks. But I just feel that it's a waste to spend the money on it only to butcher it when a custom unit can be made for less money. Unless of course it has the exact sound you want then you might as well butcher it.

The highest price I found for a custom exaust was $1000 on my truck. So drove down to White Center (lower income neighborhood in Seattle) where I knew they could do the same thing for less money. Also, $120 of that $480 bill was just for the big stainless tips I just had to have. These exhaust guys are pros at what they do. It's not hard for them to knock out some pipes and get them welded onto a set of mufflers.

I personally will create my own exhaust for my 750 since it's so simple. I'll make the cuts in the factory system where the Eisenmann and Remus guys recommend, hang my own mufflers (I have a welder) and have a muffler shop weld up the 2 to 3 feet of pipe to connect the new mufflers up to the stock exhaust. I like the systems available but I want a different tip design. I just can't bear to spend the money on one of those only to hack it up :)

its really not amazing..........the materials really dont cost that much. exhaust systems have a huge markup.

stainless mandrel bends can be had rather cheap if you know where to shop, and the straight portions are even cheaper.
the most expensive part is the labor, but if you find a local custom or hotrod shop that has experience fabricating exhaust, they will weld it all up for a couple hundred bucks.
mufflers are also quite inexpensive, even the top quality units.

the problem with doing your own custom exhaust is that you cant be sure youre going to like it!
you could very well spend $300-500 on a custom exhaust and not be happy at all with the final product.

trust me, i know..........i built 3 different custom exhaust systems until i found the sound i really wanted for my firebird. (it was a fun learning experience though)

the main benefit of buying one of the big name exhausts like the Eisenmann....they already did all the trial and error testing, have great fit-n-finish, and you can usually hear it on someone elses car before making a buying decision. you can be assured youre buying a quality product, so its pretty much risk free.

personally, i think the Eisenmann is the best looking E38 exhaust ive seen so far.

Although some of the markup is fair considering these companies have to have a jig laying around their shop so that they can make each exhaust fit the same without actually having a car to test fit each unit.

yup.........thats part of the trial and error and R&D they do.........granted some setups are much easier to build than others.

has anyone created a webpage devoted to BMW exhaust sounds?

i know over in the domestic community they have built a big gallery of sound clips of all the different exhaust setups on different engines sent in by people.

that way everyone can hear different brands and compare before buying, in case no one in your area has one you could listen to personally.

would be a good idea to get something going like that for the BMW community, if there isnt already.

I was a little reluctant to change the factory look with the exhaust tips on the Eisenmann, but I made the decision and never looked back. I am very happy with the way that it turned out.

I understand that Dinan modifies the factory mufflers by removing the baffles inside. You might look into either purchasing a Dinan setup or having someone cut apart and modify the factory mufflers if you don't want the tips to be visible.

I was going to cut open my old factory mufflers to see what baffling was inside, but I never got around to it and they were just taking up space in my garage. I ended up throwing them out.

I know that other people have kept their factory mufflers. I wonder if any of them have cut them open.

They only website I know is www.klangford.com but that caters only to the BMW E46 M3 community, however sound clips on the internet still don't do justification - yes it helps, but I've seen people place an order for an exhaust because it sounded good on the net, but ended up hating it in person.
