presently at the time i have no catalytic converter on my cavy and i've talked to other people who have done the same. all i need to know power wise for a 2000 2.4 which is better stick with what i got or get a high-flow cat. everyone that i talked to said that when they had it off their times were @!#$ but when they put a high-flow on it was banging. i just need more advice on this, as far as performance wise which is better.

With my cat off, car ran .2 or more seconds slower, compaired to my highflow cat. Same with friends cav. So we just put the high flow cats back on.

yep, thats correct. youll lose torque in the low end, plus youll throw a check engine light. go with a high flow cat....maybe magnaflow 94035.







...don't hate!.. respect people that have talent, even if it is in something you don't like or understand.

how about stats from a stock cat to a high flow?

thanks everybody! pay-day is tomorrow and the track is open i'll let ya'll know what's up
