Warpspeed 4" Exhaust

[gofastpilot]

I'm going to upgrade my exhaust system and I saw on e-bay for around $300+ a 4" system w/3" downpipe and muffler from Warpspeed performance.Anybody using this system and how much fabrication is involved........gofast :cool:

I don't know about Warpspeed but from what I have seen 4" is over kill for the 6.5TD. I do know about Kennedy's 3.5" system. For $475.00 + sipping you will get exactly what you need and it is extremely easy to install your self.

I think 6 or 7 inch is a overkill.
