Borla Stinger Muffler install on a Roush Axleback

[Todd15Fastback]

Hey folks - I just had my x-pipe replaced with the Lethal h-pipe about 10 days ago. I had hoped it would tame or replace more of the Roush muffler rasp but that is not the case.

I had the Borla Stinger catback on my 03 Cobra and the sound was just amazing. I know the 4.6 4V will sound different than the Coyote 4V. I am looking for folks thoughts on how they feel the Borla Stinger mufflers will sound welded in place of the Roush mufflers? On my Cobra, which had an h-pipe there was zero rasp on that setup. I am crossing my fingers that if I pull the trigger and get the stinger mufflers ($330 shipped) my raspiness will be gone.

Anyone care to share their thoughts if the rasp will be gone by changing out the mufflers? I really want to stick with the round mufflers like the Roush and Stingers are.

Thanks in advance!

I can't comment on Borla Stingers(different than S-Types?) swapping out the Roush mufflers, but the easiest way to tame rasp is installing mid-mufflers/resonators in the pipes before the mufflers. Dynomax, Pypes, Borla and a few others make straight through mufflers than can be welded in the pipes before the rear axle and will do a great job at cutting down the rasp.

(these come in various sizes)

And thanks for helping me remind people that x-pipes don't cause rasp.

I wonder if going this route will help and to what degree will it help? I don't want this to become an endless exhaust project .

My concern is that these Roush mufflers with an X/H will have rasp no matter what I do. This is why I want to go the Stinger (S-type round mufflers) as I know what their sound is like when paired with an H (4.6 4V, I know).

I am having the hardest time trying to get the exhaust to sound like I want it to. Did not have the issue on my 03 Cobra.

These are the mufflers.

I don't think they will sound anything like they did on your Terminator. Your best bet is the mid-muffler idea I posted earlier. If you did swap mufflers I would recommend somthing with more baffling but that wouldn't be a straight round muffler like the Roush/Stinger.

Good to know on mid-muffler.

What mufflers would you recommend instead of the Borla's?

I'm thinking of having some mid mufflers or resonators welded in my FRPP Sport kit to quiet down this annoying rasp. I like the throaty sound but the mid rpm rasp is not to my liking at all.

 

[Todd15Fastback]

Looks like the mid muffler is the way to go, it seems.

I just bought these. 2.5" and will be delivered on Tuesday. Crossing my fingers that this gets rid of the rasp. Will get them welded in behind my h-pipe.

Keep your Roush's for now and see how the mid mufflers sound before changing anything else.

Father has a S550 that we installed ONLY Roush axlebacks on, ZERO rasp. X-pipes are known to cause more rasp than H-pipes, if you're still getting rasp with H-pipes, your best best is as your doing and putting some resonators in, can't guarantee it will help however.

Yep. That's the plan.

I had my Roush with the factory resonator in place. Car sounded good. I wanted it a bit louder, hence the X and H installations.

I don't expect these Pypes to get ride of it all but most of it and to tame the rasp, if you will. Crossing my fingers.

This is what I am thinking about doing in the spring. I love the Roush axleback but want it a little louder. Was thinking of doing an x pipe and adding in 2 bullet style mufflers or resonators to tone down the rasp. Excited to hear what yours sounds like
