Quieting down a SW Catback.....

[Bryman]

So I love the sound of my H-pipe Stainless Works catback but find it just a little too loud in the lower RPMs in the cabin. I bought a ton of Fatmax Rattle Trap and plan on lining under the back seat and in the trunk to hopefully eliminate some of the low frequency coming from the back. I'd really like to keep it as the quality and sound are excellent. Anything else I should try?

Lloyd's Ultimats (a higher grade mat than most dealers advertise), including getting one for the trunk, are thick enough and dense enough to reduce road and exhaust noise. And they look and feel great. And yes, you are in the Ecoboost section though yours (and mine) are GTs. But the recommendation still applies.

I miss my coyote sometimes, don't quiet her down, let her growl.
