Thinking of trying something. What you guys think?

Have also heard the same thing, on the Apex, there is no gain on aftermarket exhaust, and yes it will slow it down, does not seem right, but that is the way it is.

I think with proper tuning and the right setup you can get an aftermarket exhaust to work, just think it is hard to do.
