I'm looking to swap out mufflers. I want to go from a bulky dual-in dual out muffler to two separate straight through mufflers. I'm torn between 6" Magnaflows or Dynomax bullets. I want a loud exhaust not an obnoxious one.
Which do you recommend?
Do you think I would see a performance gain with the straight through muffler with my FI?
Thanks,
Mike

 

i like the magnaflos, the 4" x 30" single in single out on my 07 ly6 sounds good but not too loud.

 

I'm leaning toward magnaflows, but I wonder if I would get more performance with a bullet. I'm just afraid they would be to loud.

 

Thanks for the ONLY response La Cheater.
Anyone else have info on both of these mufflers?

 

go with magnaflow. you wont notice a difference from swapping out mufflers

 

Thanks Vista. So you don't think there would be even a small gain with a straight through muffler over a chambered muffler?

 

Im running magnaflows on my SS and love them. Technically they arent mufflers, theyre the resonators that come with the cat back kit, im just running them as mufflers. They sound awesome and you can get them for about 50-60 bucks a piece. Part number from magnaflow is 14416. Search them up on eBaymotors.com or on magnaflows site, just watch the price differences! No drone in the cab at all (noted i still have the factory tailpipe on) and very loud at WOT. Would recommend them to anyone!
