I think this might belong in the gen 2 lightning thread but since its a cat question i figured this section would be ok,anyways im going to a muffler shop this wednesday to get a bung put in for my wideband i already asked and of course they say they wont remove cats because its illegal. now im looking for a way to bump up the exhaust tone without having to go to a different set up. I know there are high-flow cats but im not sure if thats actually going to up the decibel level any, another option is hollowing out the cats but i dont know anyone whos ever done that. Basically im looking for any tips what do you guys have?
