Not that I don't see the merit just don't know why you would want to brake the law and void your engine and smog warranty unless it was a track only car. |
I not sure about the legality of an aftermarket downpipe but I do know installing one voids your entire powertrain & emission section of your warranty coverage.
In fact, some dealers would strait up refuse to work on a vehicle with an aftermarket downpipe, if the problem seems reasonably related to the modification.
Also, all major emission control devices and ancillaries (catalyst, turbos, ECU, etc) are extended for up to 8 years or 80,000 miles mandatory manufactures coverage.
So you're pretty much throwing that extended coverage out the window by tampering with the catalyst.
