Hi Guys
Who has replaced their NPP muffler for Flowmaster Super 44 series mufflers? I just want to improve the weak stock exhaust sound for something more appealing, but without expending a fortune, most axleback exhaust for this cars are very expensive. Please share me your experience with them.
I already tried the npp muffler delete, but it was too much for me, starting with the wake up call with a shotgun explosion on the mornings
and the deafening sound while driving the car cold. In just one week I returned my car back to stock npp.
The secondary cat deletes. Is also not an option for me because of the high droning sound.
