Hey guys, I was wondering if anyone had experience with running different mufflers with Supercharged applications? Specifically, I recently re-installed my factory Mustang Mufflers coming from the more open and much louder Roush ones. I'm still running an offroad X-Pipe, so the exhaust is still mostly open flowing aside from that.
I know that in an N/A car, the difference in power here would likely be zero or less than 1-2HP or something along those lines. My question is though, doesn't that change once you're at a certain level of power? I know that this probably has an effect moreso on a Turbo car where backpressure is an important factor, but am I losing power running my TVS at 10psi on E85 with the factory versus the Roush Mufflers?
I'll mention I recently switched over to E85 at the same time I swapped the factory's back on, so I don't have a good butt dyno benchmark to compare, but power-wise it felt the same on corn as it did on 93. It also might just be the weather though, it was getting up there around 85-90 with 75% humidity so that might be it.
In either case it's a nice change of pace going from a car that you can hear 5 miles away to more of the sleeper mode with the TVS being much louder than the exhaust, which you can't hear more than a few blocks away in comparison.
