What 3" catback do you have that doesn't bottleneck down to fit the stock down pipe. I have the punishment racing DP but cant find any catbacks besides the Thermal R&D and Apexi.

how long is the part that bottlenecks down?I have an hks which does bottle neck but I had that piece cut off and had a 3" piece welded in.
But then I got a ST rear sway bar which hits the axle back section.
Yes I want to find a cheap one that doesn't bottle neckSo are you asking which cheap cat-back exhaust system fits a 3" downpipe? Because you already know Thermal and Apexi works, but so does STM's stainless cat-back system. I currently run a Thermal and Punishment dp and fitment is great, true 3" though out. However, if I ever need another I would go with Thermal again or STMs, which has a lifetime warranty and weighs less than 20 lbs.
