I have a 2001 Xterra 4x4 auto with the 3.3L v6. I'm considering putting straight pipes (duals) from the cats back, no mufflers. I called my local shop to get a quote, and the guy told me that nissan and Toyota owners often complain from a loss of low end power and acceleration after exhaust is...
I'm seriously considering straight piping my 02 SE, but i'd like to hear more as far as pros and cons of doing it and not doing it, and my main question is will it cause too much backpressure and crack my headers?
