Agreed...also remember that even if you hollow your cat out you will still be revving through a freakin 1.75'' OEM pipe. Ughhh.female four said:Probably be easier to just buy a striaght pipe.
All it is is just a piece of pipe with flanges on each end to mount it up to where the cat use to be. What ... like $20 tops?
Thats because doing it that way sucks.96civichx said:i got it hollow and put it on and drive it it sounds like shit it makes a radle sound i got anotherone that stock i might just put that in or put a pipe right thought the hollow one and make it a stright pipe u rhink i can do that
You don't need FI do use a test pipe. Race cars don't even use it... they do open header.tdoto_ said:you should just put the other one on and leave it,the stock cat has a good design,you only really need a aftermarket cat if FI is involved.
N/A cars will see small gains from a high flow cat,so you could use one if you want,but in reality it is a waste of money.................also i never mentioned test pipes,i said you only really need a aftermarket cat if you have a turbo ect.female four said:You don't need FI do use a test pipe.
