Race exhaust

Well ****..... That didn't work.
First track event on the aluminum setup, I found the muffler outlet piping was moving around and burned my bumper cover. Dug in deeper and found the core had come apart . Damnit leafy! You were right. Once the packing was all blown out the case ballooned up. I had a pretty massive backfire issue on overrun so that may have been the culprit. Need to get decel fuel cut enabled and stop that nonsense. It held up fine to 3 auto x events, and street use.
Next step is a floated stainless core and .090" case this time. I'm probably going to reduce the muffler size as well, this one was stupid quite.
