ANY other exhaust you pick is going to be REALLY loud with just a midpipe. Don't forget that the porting is going to make your motor alot louder as well. If you do decide that you want something bigger then I agree with Bacon's choice. If you're going to be loud you might as well go bigger.https://www.nopistons.com/forums/pub...IR#>/smile.png

Vosko just dyno it first. If you're not happy with the numbers you can borrow my sightly bent n1 dual and see if it makes a difference.
