one of my catalytic converters went.

idkn much about exhaust systems.. so if people can help me out that would be great..

should i:

gut the catalytics

put x-pipes on

or put straight pipes on..


or if anyone anyone has a better idea other than buying an exhaust system please let me know..

that is unless a new exhaust system would not be expensive..

thanks

 

buy hi flow cats

 

do hfc's make it raspy?

 

hfc's make it less raspy than test pipes. gutting your stock cats would give your more hp similar to test pipes. x-pipes has more to do with your exhaust setup than cats. all depends what you're looking for - performance/sound/cost?

 

i am going to jack this thread for some of my own questions about this..

so what about gutted cats, aftermarket ypipe and a coupe midpipe with stock sedan muffler.. would this setup be raspy? and would i have a cel for the gutted cats?

 

stock muffler should keep the rasp down but "test pipes" and headers are the 2 biggest sources of it. so yes it will be, but its hard to say exactly how much. not sure about the cel, you can always use non-foulers to space the sensors out of the air flow.

 

thanks guys im gearing towards gutting my cats.. however i have question in reguards to that...

will my service engine light stay lit up?

 

dunno. try searching for gutted stock cats.

 

from wat i understand x-pipes will even out exhaust flow and thus improve performance slightly. i dont know how this affects sound at all. from wat ive seen exhaust systems with x-pipes make slightly better hp.
