Pro n cons about cutting your

6 Answers


PRO..it will sound loud and cool,Con..you may damage the car by removing the exhaust,it has 02 sensor,s that are made into it,and a catilac converter,in which tells the car how much fuel it needs,may not run right.


If you want a real performance gain get rid of the exhaust manifold and install headers. Cutting an exhaust pipe after the manifold doesn't do much, when the restriction in flow is caused by the manifold. Plus the O2 thing.


Cutting the exhaust pipe is foolish. If you want a performance sound replace the muffler or install a cat back exhaust system. If you want more performance install headers and a catted x-pipe system. Be aware if you install headers you will likely need a different ECU tune and a tuner.


CON - Tickets for noise and your neighbors will hate you and you probably won't see any performance increase.


Pros: none. Cons: you sound like you just had your cats stolen


Con: never passing another emissions test.
