In general I love the Mach 1 exhaust, and in track mode it's plenty loud enough. Considering possibly an H-pipe just for a little deeper tone / less splatty noise at high RPM's. Probably not doing an X-pipe. Anyone with only the H-pipe as an exhaust mod (no headers) that can comment? I had an H-pipe on my 2018 non active exhaust and it made it louder but more buzzy / tinny so I put the resonator back on.

Yes, I only added Steeda H-pipe, and you'll be very happy with the deeper sound. Plus, make cut a little shorter (1/4 inch) and pull exhaust forward to eliminate issue with active exhaust harness rubbing into frame and cutting wiring.

Yep the wiring issue is real, look at this photo, 186 miles on my M1HP

Will you be taking it to the dealership to be fixed under warranty, or repairing it yourself? It’s doable, I had to repair mine because no one has the harness in stock.

I bought two harnesses as they're the same part for left/right, $25ea fixed. Really no time for Dealers unless major issue.

I hear you. I like to stay away from the dealer as well and only visit them if it becomes absolutely necessary.

Do you happen to have a part number for the harness?

I did the Steeda H-pipe myself. It's perfect. More pops and gurgles. Sounds the same as stock with a noticeable volume increase.
I recommend double wall clamps over the single wall ones Steeda gives.

I think I'm one of the few, but I HATE how 5.0's sound. I tried everything to make one sound good, X, H, Mufflers, Combos of that, and all ended with rasp. I've stuck with my Factory exhaust as its the least raspy option

If you HAVE to put something on, a Double H

Do you have a part number, where you purchased them?
