      Perfect muscle car sound.

      This is exactly what I was looking for: Loud cold start that turns heads, perfect old school muscle car sound under acceleration, pops and crackles, not raspy like an x pipe, with zero drone on long highway trips. I have to clarify my loudness rating of 3 stars. For a 5 I'd put long tube headers with an x pipe and muffler delete. A 4 would be a Corsa X treme or similar. You will hear this exhaust all the time in a pleasant way, NOT in a droning way or sharp earsplitting rasp. It could wake up your neighbors with a cold start, but won't get you evicted. 5 stars for quality, increase HP a bonus. You can't go wrong.
