I need a new H pipe and was wondering if i should just get a stock one or go with an aftermarket one.My car is pretty much stock except for MAC headers (im pretty sure they are ) and a Magnaflow cat back.Any sugestions?
Why would you want a stock one? Get an aftermarket piece.. It will be cheaper then going to Ford and spending 500 bucks on a stock one. Go with a Prochamber! They are the best, handles down.. not because I have one, but because they flow the best and make the most power.
yes it will affect it... you can get an aftermarket one with cats that flow allot better then the stock one. I have a pro-chamber on right now, i bought a used stock one for when i go through the sniffer in NJ. Cost wise, either option will cost you about the same.
Go aftermarket. that way you can get rid of 2 of the cats and have a better flowing exhaust all together. You shouldn't have problems with emissions as long as you have at least 2 cats.
