Hey everyone I just have a question...

Is it the same to just "gut out" a stock CAT, than to buy one of those "high flow" CAT's? I know the stock one are bigger and the air would get to it and then expand...but would that slow your car down? or limit gains from opening it up? Steer me in the right direction guys, thanks

just get a test pipe from xtremers, hes a member of this board. he makes em for 45-85 bucks depending on if you want it resonated or not.

Get a test pipe. Then you will still have your CAT just in case you need it someday for somereason. Its a much cleaner setup anyway. Think about it, what if one day you get the shits of how loud your car is, then you would have to go searching for one. New or used it will not be cheap!! But in the end, its what you decide
