I'm ready to change up my exhaust.. Really disappointed with the magnaflow sound & performance. Think I'm going to run a dual muffler setup & see how I like it. Not unless someone has a better idea. This is what I like if it helps. I love the flowmaster sound, but hate the performance, like the mangaflow performance,but hate sound.

What I've had on the truck so far
4.8 stock with hypertec
Factory Y with cats, Y'd again straights out the back. Probably the best sounding.
Stock 6.0 with hypertec
Full SSS stock exhaust system. Then I replaced stock muffler with big block series flowmaster.
Then installed cam with obx headers, ones designed for the SSS.

Mods in sig.
Swapped headers, with dual 3" with the flowmaster Y'd into single tailpipe. Then I swapped over too the magnaflow with the same tailpipe. Then I remove the Y'd tailpipe & added two pipes coming out the side.

This is what I'm thinking about
Straights
Dual flowmaster 10's with H pipe
Dual something else?

Tell me whatcha think.

Flows sound great imo, but people say the performance gains are not there.. How about a set or dynamax bullets or borla Xr1's? It would seem as your looking for something loud based on saying flow 10's..

Well it's a 1 to 3mph difference between the flowmaster & magnaflow, but still having to open the cutouts @ the track. Magnaflow sounds like it's farting @ idle. Some like it, I don't.

Guess I want something loud when I go wot & no drone while crusin. Something that really show my cam off @ idle like with the flowmaster.

I run Lts with ory in a si/do cherry bomb extreme. It has a deep throaty sound to it kinda like a flowmaster. Looks like a mini flowmaster. You could always run straight pipes with glasspacks. Lol I think those 10 series will be loud

It's kinda hard to know what will sound the best. I've been checking out the sportsman borla xr1's. Most guys on here run single exhaust & most of them sound badass.

I run Dual flowmaster 10's and love them. Get alot of compliments.

I had a single 3"dynomax bullet prior to this setup and these sound 100% better IMO. Power gains don't count because I swithced to true duals over the choked Factory cat back connection.

Sounds pretty good man. Just a little on the loud side. Could just be where you got them exiting at. I'll probably wined up with the 10's or 40's.
