Awesome yours sounds good too! I found the exhaust setup in my vid. A lot more work needed then I wanted to pursue at the moment unfortunately lol |
I honestly wouldn't do the RPI's, my old setup I did no secondary cats and no mufflers and it's horrible for daily driving/drone in general. If I were to do it again I would do headers+section 1 (no secondary cats) and leave the stock Xpipe and mufflers. That's what I'm going to be doing on my current car. If it's a track car or you want the big weight savings from eliminating the mufflers that's another thing.
