Re: Removed stock muffler PT Cruiser GT. It sounds great.
The srt-4 has a couple of 14" resonators in the midpipe just after the cat. The main thing about an aftermarket catback exhaust is they are at least 2 1/2" in diameter whereas stock is only 2 1/4". Stock is fine if you are staying at Stage 1 numbers. If you are going beyond S1 numbers then you are going to need a larger turboback exhaust.
