Anybody else done this? I did this with a 70 Series Flowmaster, dual 2.5" in and single 3" out. I gained some low end up to 2500 rpm and lost some from 2500 to 3500, top end feels a little better. I'm pretty sure I picked up a little MPG, but with my driving style it's hard to tell.

Anyways, I'm not happy with the Flowmaster. The sound is perfect for cruising, a nice rumble. But when I get on it, it goes almost silent. Now looking at the specs on my muffler, it's a 3" in and 2 2.5" out, it doesn't say anything about being reversable on the flowmaster web site. So...I'm thinking of sticking a Magnaflow in it's place, a 12588, it is reversable.

What do you guys think?

 

Mine has true dual all the way back, 2 40 series mufflers--- I like it but wanting to change it from exiting out the back to infront of the back pass tire.

 

Hey Travis, how you liking the silver vents? The black ones look good.

 

They look Great!!!
