Mufflers with the least rasp?

[alex3610]

Currently have Roush axle backs. Even with everything else stock, at higher RPM they sound too raspy / trumpety / farty (I think I'm just making up words now. I plan on either doing cat deletes or an off road H pipe, and I know this will only exacerbate the problem. So which mufflers will give me the least possible rasp when running without cats? I'm thinking Borla S-Types, but the only video I found with them and no cats also had the stock resonators removed, and there was still some rasp. Anyone have that setup? (Borla S-Type, stock resonators, off road h pipe?) Thanks guys!

Agreed. I just finished up mine today Kooks bullets in place of resonators and kooks axle back with jegs cat delete. sounds great, with NO RASP.

I like my flowmasters. YouTube "boostaholic01" there are a few videos of my car. Or search "Aed e85 Paxton" should pull up my car

Flowmaster American thunder's or Borla S-type's are the least raspy

GT500 mufflers sound great IMO. No drone on the highway either.

Flowmaster american thunder sound real good

The stock mufflers on my 2014 were raspy/trumpeting bad at more than half throttle after removing cats and resonators. It was ugly....yuck!

Replaced them with Magnaflow Street axlebacks. Perfection! Deep idle tone, old school muscle growl, very nice WOT.

Yea once you remove the resonators it gets damn raspy. Had to put dynomax bullets in to get rid of the rasp.

Kooks.

but drone real bad. Bassani race axle backs have no rasp as well, at least from the videos I've heard

This.

People give GT500s shit because they don't cost $800 and have a brand name, but they really have a mellow, bassy sound to them.

I never liked my GT500 mufflers with the ORX pipe. Sounded way to raspy at everything other then idle.

Really? I have that exact setup and it's not raspy at all. Coming from a 2009 GT500 which every muffler I put on it sounded raspy.

 

[MRSUPRA]

/\Yeah, to me it didn't sound good at all. Maybe raspy is the wrong term, just sounded like bla bla noise. And I do still have my resonators.

 

[chefron50]

I went with the borla s, no issues at all,nice deep sound.

gt500s + no cats = RASP!

i have cat deletes with dynomax race bullets in place of resonators, with no mufflers, and they sound great. just a little louder then most would like.......SO add 2 more where the mufflers were PERFECT lol
