3" Resonated Double H-Pipe (2015-2026 Ford Mustang GT/Dark Horse)

Like the other reviews, if you are running catless headers, doesn't matter the brand it could be kooks, stainless, bbk.. you are going to have horrible rasp. I'd almost argue this deepened the tone more than the factory headers and single H pipe I had. This is the perfect amount of volume but still keeps things quiet enough to not piss off everyone around you (mainly in the low rpms). One thing to note if you have the opportunity to have a shop weld all 4 sections in do it, will the clamps works probably. Is it way more secure with welds absolutely.

Lastly, for my setup I am running the factory ford valved mufflers, the in cabin sound with the valves closed sounded so bad with the amount of rasp/drone, this completely eliminated that and I can actually have a convo in the car again. Don't get me wrong it was fun to run basically a full straight pipe for awhile but this is just so much more refined.

My 2022 Mach 1 has such a clean tone to it. I originally had a single 2.5 inch h pipe with stock headers and exhaust at one point. I then upgraded to catless long tube headers which upped rhe sound alot. Only problem was that it did create unwanted rasp. The double h resonated pipe fixed that!!!!! I still have the stock active exhaust which I have no future plans on replacing. The quality of sound and volume mix almost perfectly. I love it!!!! Nothing like it on the road right now so I feel special for now before more others find out about this
