Hello, I have a 2021 GT 6 speed with LTH brand catted long tubes, x pipe, and Roush axle back mufflers. Loved the roush before I put the headers on, now it is a little too loud. I love the black roush tips and they have a sweet R on them, I’d like to keep the tips and swap the mufflers to something a little more tame. I am even considering an H Pipe to mix it up. Any suggestions?? Thank you!

Ditch the X-Pipe strangler and go H-Pipe with two of these (see link) after the crossover. I’m unsure if your mid is 2.5” or 3.0”. Keep the axle back you have.

i had your set up, then added headers like you and it got too loud. i put in some vibrant bullet style resonators and that def helped bring it down to a more tolerable level. in the end my exhaust was too frankensteined so i ended up cutting out the xpipe with the bullet resonators for the resonated magnaflow xpipe and that seemed to get it back to where i was comfortable with it. def cheaper than new mufflers
