I have no performance mods but am considering gutting or deleting my cat. My question is what kind of low end or high end power hit/gain am I looking at? Will I need to get a tuner to compensate for the gutted/deleted cat?

 

you may gain a little performance, i got a little, but mine was falling apart, mostly though it will sound better

and you won't need a tuner

 

don't for get you need some back pressuer or you well burn your valves up

 

im sure u would have to run no exhaust at all to get close to that. tons of people run straight pipes.

 

i have no cat (y pipe) and a glass pack dumped in front of the rear tire and have had no backpressure issues...plus it sounds wicked...when it's not leaking
