Installed CP-E's exhaust today. Install was not difficult at all - hardest part was removing the stock exhaust (CP-E suggests you use wd40 to help get the exhaust off the hangers and I have to agree). Exhaust comes with everything you need and comes with excellent instructions. I have a dyno scheduled tomorrow and it will be interesting to see what the gains are - butt dyno says it is a significant gain. Boost comes on sooner, but otherwise boost behavior is the same.
The sound is a deep rumble at start-up, but very quiet at idle. It gets fairly loud when you get on it, but it not obnoxiously loud. There is no drone on the freeway. I can only compare it to the other exhausts on cars I have owned... it is a bit louder than the miltek exhaust (cat-back) and about the same as the miltek turbo-back on the S4 (B5) and more quiet than the APS exhaust on the STI (although that was a turbo-back). The exhaust weighed in at 22 pounds (11 pounds per piece). I didn't weigh the stock exhaust - it was too big to balance, but I'd say the CP-E was about 1/3 the weight of the stock exhaust. I am now anxious for CP-E to release the downpipe because I think we are going to see huge gains with the combo.
