    My exhaust manifold and down pipe are glowing red hot and you can smell the metal like its burning... Is this the problem of a bad CAT??? My car has been stuttering at high RPM or whenever the SC kicks in for awhile....Oh also does anyone know what these cars are like with no Cat??? Loud?? Too Loud??

    Any Ideas??? Thanks in advance

    Definitly sounds like a clogged cat. Replace it, or go even better with headers or just a 3" downpipe with high flow cat. You'd probably notice a huge difference the second you touch the gas pedal if the one you have now is that bad.

    the stainless will just last longer, but honestly even the mild steel should outlast how long you have your car.

    Nope it won't improve performance and as bio said the normal downpipe will most likely outlive the car.
