TTI Exhaust

I posted this 2 years ago... My opinion has changed a bit. The mufflers I went with smoothed out after a few weeks and Im very glad I went with the ones I did.


TTI 2.5” X-Pipe, 340 HiPo manifold system review.
In short I love it. The system fits the car very well. Only minor modification to clear the scatter shield edge an the RH side and I needed to give just a bit of extra clearance for the clutch fork. Installation was less than fun. I saved some work by using a saws all to remove my headers and the installation of the manifolds was relatively painless. The hard part was getting the 5 pipes (2 pipes from manifolds, 2 intermediate pipes leading to X-pipe, 1 X-pipe) all to slide together at the same time. Its a process very hard to describe, but with enough head scratching and a bit of lube it went together with no tools. The rest was easy. I would say this is a job that should be done a lift (glad I had one to use).

I went with the Dynamax Ultra flow option and find them a bit boomy when looping around town but do smooth out as the RPMs start to come up. Idle sound level is very good (in muscle car terms). I think I would have been a little happier with the regular super turbos as far as sound, but wanted max flow for a manifold system. Cabin noise is much improved over the headers.
