My old original exhaust was getting rattly and falling apart, so over the weekend, I cut it all off and built a new one. Starting with the OEM manifolds and y pipe, I added a single-in-dual-out chambered muffler, and then ran dual side exits just in front of the back wheels. I still need to make little shields out of aluminum so that I don't burn the paint, but I'm super happy with how these turned out!
Here's a video of how it sounds:https://www.facebook.com/1308096100/videos/pcb.10226345452805184/10226345450725132
And here are a couple pictures of the plumbing.. Eventually I want to get the Patriot style sidepipes, but this works great for now and sounds good. It's also not even loud on the inside. I love it!
