Has anyone put on a high flow catalytic convertor? If so what kind of effect did it have on the car? Also did the O2 sensor after the cat. read alright? Or did the computor throw a code? Please get back to me.

 

people have done it, but in my opinion, it will sound like crap, and wont give you any gains

 

I agree.

 

I didn't know it would sound different than the stock cat.

 

Thanks for all the comments guys. It has made me think about it more now. Thanks.

 

Actually I put a 3" cat off my header and it didn't change the sound of my exhaust system at all, just made it a little deeper at higher throttle, which is a good thing. Taking it off completely from what others have said, DOES sound like crap, but if you want the hi-flow cat, just get a larger diameter one. It definately does not change the sound at all though, I didn't even notice the sound differance from my stock cat to my 3" cat. Cat was def. worth it tho! When i saw my stock cat and downpipe, i was very sad to see how long i had left it on there, because it's very tiny, although it's not the worst thing in the world, its actually considered a pretty satisfying flowing cat for stock.

 

i was thinking of going wit a magnaflow high flow cat, but if it doesnt do anything den i dont think ima get it

 

sometimes you might loose some back pressure..
