Bit of a story I'm about to type but it helps with my review of a muffler delete vs aftermarket exhaust.
I recently had the bilstein b12 pro kit suspension put on the car which lower it an inch all around. When backing into my driveway the car bottom out, knocking the clamp loose that was holding on my RPI exhaust, so basically my exhaust ending a little after the resonators. I didn't realize until I went to drive again in the afternoon and it sounded louder, and IMO more like an American V8 with the gargles. It also seemed to have a lot more resonance in the car, I have two car seats in the back and they were vibrating almost constantly. Personally I didn't like it and took it to Midas first thing in the morning to get the clamp welded into place, I threw away the stock exhaust years ago anyway.
Since sound is a personal preference kind of thing and some people don't want to spend $1k on a muffler, which that is all RPI is, I can understand those that would just do a delete and a straight pipe. My personal preference is I prefer the smooth kind of sound you get from RPI over a delete. At the end of the day we both have better than stock sounding car and that's whats important.
