The question is does the exhaust add horsepower you can feel....also any mileage increases?

[VA Raptor]

As far as I know no bolt-on exhaust is going to add any substantial horsepower gains. The main reason to swap out the exhaust is for the sound.

Now, if you're doing longtube headers with an X/H pipe, than yes, you'll have an increase in power that you'll feel.

Well, sadly I have to say I got to take off the Roush exhaust. It sounds great slowing down and at WOT and at idle. But the drone at 2000 RPM is too much for my ears. Most people don't have a problem but my ears are bothering me alot with the sound. I already have some hearing lost from years ago and my ears are much more sensitive to that drone than most people.

So once I remove it I am going to try to sell on Craigslist for about $400. Once I sell the Roush I plan to go with Maganflows. I am really bummed out about this but I got to think about my hearing. 8-(

Wow that sucks man. Good luck on your hunt for an exhaust without drone.

Maybe a set of Corsa Joe, no drone. Sound a bit different too.
