Dr Gas offers a kit that is Weld together so it is somewhat custom fit. The H and X help equal out the pulses in the exhaust and should perform much better then straight pipes.
thats what I just got quoted for custom 2.5" H-pipe...no cats at local exhaust/muffler shop. So my car is there right now getting outfitted with their setup.
Am I going to have a check engine light from the O2 sensors? They are maintaining O2s and the smog pump hookups.
Nevermind on the MIL issue. finally found a thread just searching "MIL" instead of "MIL eliminators" and found out I don't need it, only the modular guys do.
They look great. They sound great. And the bottleneck between the headers and mufflers is gone, so WOW.
I suggest that you all go to your local shop and see how much they will do yours for instead of paying big money for the brand name.
Custom H-Pipe = $107, parts, labor and tax. They said they'd never do them for that little anymore though - welding the joint up at the headers was annoying they said.
