LTH Install Too Loud

[rcwilli7]

I did things backwards and just installed Stainless Power long tube headers with high flow cats after being boosted for about two months and now the sound is crazy for my car. I have Roush Axle backs and a X Pipe and the rasp/tone is INSANE at WOT or anything above 3k RPM. I’m looking to tone down the sound/rasp at the higher RPMs but I’m not sure what to do.

I have read that resonators will help but honestly I wouldn’t mind getting a new axle back because I’m not a fan of the Roush look and the way it sits in the rear valence. It’s on me for buying a known raspy axle back but now I need suggestions on a new axle back.

I also do not plan on installing a H Pipe unless absolutely necessary. Thanks!

It would be expensive, but put this on the car if you want great sound without being obnoxious.

I was just gonna say the same thing… good setup if you want quieter pipes

I’ve been thinking about getting their S Type with a H Pipe since it’s not as loud as the Roush. The Roush is just too much

i hear a lot of good things about awe touring to tone it down but still sound good or corsa sports

I have the Borla Touring. It was the ONLY exhaust I knew would work for me. I run Kooks catless w/LT's. I can be as quiet as I want, but it still opens up with perfect authority when I want it to.

I’ve got the Corsa Sport and zero issues with the issues you’re describing. I switched from a Magnaflow Street which had similar issues you’re speaking of.

Man they are not cheap either but I guess you get what you pay for. Never should have went boosted

I had the same problem with raspy sound. Got rid of the X Pipe and the track muffler setup and went to MBRP touring setup with H pipe, much quieter, no raspiness, more of a deep rumble yet plenty loud when you get on it, but I am not running headers, just stock manifolds and cats. MBRP setup was comparatively cheap being less than a thousand for the catback system.

Not to pound on the OP but WHAT did he expect, modes?
Boosted
LTH
Suitcase delet,
X pipe
Roush Axle backs.

What can I say, got what he paid for, sometimes dreams and reality clash, and reality always wins?


As to Roush Axle backs are loud, and not fitting" the way it sits in the rear valence."

I will address both, Roush has IMNSHOP the best angry, crisp, aggressive pitch out here.

I have low rumble in the 34, roll cam, stroker V8, that's what I think the Mustangers are shooting for .... never happening.

5.0 coyote is a different animal, sound and pitch reflect that. Something to be celebrated

Next, the way it sits in the rear valence, please point out what you dislike

I am inclined to believe your dislike is with the installer and not ROUSH.

Enjoy your hotrod build sounds tuff, more than enough power for the street and car show (car shows whoopie) scene.

This. It should help tremendously with rasp and somewhat with volume. If you like the tone of the car currently, this would be the way to keep that but at the same time quiet it down and reduce the raspiness.

Where did you get the touring from? I only see the MBRP Street with H Pipe for 2018+

I was fully expecting this but had (some) hope it wouldn’t be too crazy. Honestly the install is probably what is was more than the exhaust because it sits lower from the rear valance than yours. Loved the sound prior to LTH but damn it’s too much now.
