I had to drop my front sway bar an inch, and have my non-turbo k-member modified (they sell turbo K-members that make it better) but I was able to fit a full 4" downpipe and 4" exhaust all the way back to my 3" muffler where it was reduced in my BW S484 turbo.
Made 870 RWHP with exhaust fully on. I dropped the exhaust off at the downpipe and picked up a few pounds of boost and it put down 1,008 RWHP. I am confident that if it was retricted further to 3" at any point in the downpipe, that a much greater reduction of power would have been seen.

Maybe it's my Huron AC kit, but no way am I fitting 4", let alone 5" Spoiler!
Hi, I'm doing a 99 Camaro, BMR Turbo K, Huron AC there! I was looking at splitting to dual 3.5", oval pipe, but I'd even have to run my pass. Side under the K with a bunch of oval pie cuts! Any other ideas? Too much motor, i need the flow so I don't have back pressureissueson the street... Thanks!
