Hi Eric!

Are the 2,5 packed really a lot quiter then the stock Superformance?
Do you sell complete sidepipes too?
Mine is runing on stock mufflers and the old Superformance headers which have a small port (to small for the heads) But it can not be so bad because the engine have 542 at the flywheel and 450 at the rear wheels. Of course there are allways possibilitys to get more hp...but i am not sure if it really makes a difference if you have 20hp more.
