I'm putting magnaflows on my truck with true duals in it tihjt now I was wondering if I should put a dual in dual out or run 2 single in single outs??

 

You running an x pipe? Cats?

My duals were a work in progress. Started out catted, straight to dual maggies. Nice sound but had some rasp and it droned from 1500-2500. Next were the lt headers and went catless and was way louder and raspier and droned pretty much from 1500 and up. That lasted a week then put an x pipe and resonators an couldnt ask for a better setup. Sounds mean with no rasp and drone has been virtually illiminated.

Even Justin (BBP) complimented my exhaust at the tune

 

Its probably gonna be quiet either way, I'd say go whichever is cheaper and easier and it sounds like the dual in/out setup would be.

 

I put a dual in/out on mine but i wasn't running a x or h pipe before hand. I think I paid $90 for mine off of Amazon. I think it's a 18"? Barrel magnflow. I couldn't be happier with the sound.

 

Anyone run stock from cat back with CAI, LT HEADERS, y pipe with cats? How does it sound?

 

Ive done lots of exhaust systems. If u can find em put some forzaflows single single. They r loud and soud better than a flow or amagnaflow. Even tho they r a flowmaster knock of they really have a better more raspy sound. My best friend owns a exhaust shop. I built the muffler i have on my truck now
