which exhaust is better?

[m3f_Carlos Trahin]

i was wondering which exhaust system would be best for my '95 m3. I'm debating on B&B Triflow and UUC T.S.E. --which one sounds better? I don't want a super loud exhaust but i want it to be heard..more on the loud side than quiet.

If you don't have the Euro HFM kit yet, do that first. There is not much gain from an exhaust, maybe 3-4 HP, and a lot of noise, and about 25 LBS less weight.



For a couple Hundred more, you can get about 20 extra HP from the Euro HFM kit.

What exactly is a Euro HFM kit??

i got an eiserman catback exhaust and i love it...do some research on it.

What year is your car?



If its a 95 and you don't have to worry about emissions, get a track pipe. Thats roughly 20 hp for 500 and your car will sound mean.



The HFM is well worth the cash too.

Active Autowerks is the best exhaust, bar none.

not aways. AA doesn't have the best dyno numbers nor are they the lightest.



UUC does beat them out on there U system. but again UUC U system is loud.... and the AA sounds totaly different.

I had UUC's cat back.....I was not impressed, and your right....too loud. But I love their short shifter. I went through 2 before I found them.



AA has the best setup and quality that I've seen. The sound is pleasing to the ears, and when combined with the track pipe and software upgrade....say good by to UUC's dyno results. Besides, UUC's dyno results advantage...at least when I last looked was peanuts. AA makes first class add-ons, quality construction A+.



But for forced induction....I'm thinking Eurosport twin screws.

Dyno numbers? I thought aftermarket M3 exhausts were really for the sound and appearance as they're not that restricting and thus provide minimal gains. I think if anybody is purchasing an exhaust based on dyno numbers needs to check them again. You're not going to get much out of them.



With that said, AA's exhaust is ugly. What's up with that muffler shape? Also, I like my exhaust loud so AA is not loud enough. B&B baby!

Hey! I've got the AA catback/track pipes! They're f#%n' great.



Anyway, I think it's just a matter of preference; as long as it doesn't scream ****! I agree with 97BLKM3COUPE, you'll notice a significant difference with an aftermarket intake. Euro HFM, definately worth the price, from what I've heard for the 95. An exhaust is simply the looks and definately the sound that keeps your foot in the pedal. After changing mine, it was like having extra toppings on my dessert platter of fine german tuning.
