So i've been reseaching this for a while have finally come down to 2 different exhausts to go with, the AA Gen III and the UUC System U. Both have been dyno tested and proven to yield results. I've heard both of them and they sound good. What does everyone here think? One draw back i've seen with the UUC is the fitting isn't that great and it is difficult to put on because snaking of the pipes is required. And the AA weighs 34lbs compared to the UUC 25lbs. I know a lot of people prefer other brands and what not, but for what i'm looking for this is what i've narrowed it down to.

What do you guys think? AA GEN III or UUC System U and why? thanks

When I was doing my research I came across your link and have already listened to it and it sounds AWESOME!! Thanks bro. It makes me lean towards the UUC, but the AA sounds good to. How are the gains? HP TQ

i think the aa may be a tad bit louder but its more expensive and heavier.. i would go twith uuc, plus i like how it looks.

i still dont understand why these things are so much, its only the exhaust from the catback up.. gotta love bmw's

So dude...but it's just an exhaust..gains are going to minimal no matter what...doubt you'll even notice it...Although I can tell you the System U was rated with the highest gains..

Holy shit furious, I remember that. I still have that link lol. Anyways i'm a bit more biased for the UUC as I think i'd trust it more than the AA.

Thanks for the link Furious, I actually found that link a while back which is what has basically narrowed my search down to UUC and AA. I emailed UUC and Understeer.com for more info about the exhaust and they obvioulsy told me to go with their product, but they told me another interesting thing. They said they have dynoed their System U against the AA and that they are very similar in gains, but the System U is much louder and the AA is only moderately loud. I found this interesting bc if you watch any of the videos of the AA and then videos of the UUC it is pretty clear that the AA if just as loud if not louder. Plus, i've personally seen both exhaust and heard them in person and the AA is louder at lower RPMs and at Idle, but at WOT they are very similar but the AA is still a tad louder. Both cars had intake and and software, neither had straight pipes. I know companies try to push thier products, but that's just straight lying.

It's still a toss up to me. It seems this board favors the UUC and other Bimmer boards favor the AA. I'll let you guys know when I have come to a conclusion and why. So far, leaning towards UUC because of the 9 lbs weight difference.
