I had a muffler shop install a dynomax hiflo with a bung for the 02 sensor on it after I installed a JBA header. Works good and sounds even better. A little more pull than the stock ex & cat. The only reason I changed it was because the stock cat was leaking and coming in the car.
I would have left it stock but the factory cat was $750.00 from the dealer. Header & Dynomax cat was cheeper.
Later, Scott
