I love the way these sound and was wondering if you guys wo chime in. I have 383 that is 417 rwhp with an A4 and curently running a Hooker catback. How much do your guys think i might be able to pick up running a Dual 3" with x pipe with 3" dynomax 24" long with dumping right before axle. I was thinking a 2.5" would not be enough. And you guys know where the cheapest place to buy this set up would be?

Thanks guys

 

anyone have anything to add??

 

its hard to say what you will add, i went from a magnaflow catback to 2.5" with TDs and 18" dynomax bullets and it sounds good and is not too loud. I bought the universal x pipe kit from summit. It went together very well, i mocked it up on the car then welded it all on the ground so i got good welds. I am making 350rwhp right now and honestly couldnt tell the diff between the 2 exhaust. I plan on going LE3 on the top end and i dont think the exhaust is going to be a restriction

I would go to texas-speed for my true dual setup. They have it with or without cats (I think) Either way, they have great products and great prices.
Texas-Speed
