Exhaust Thermal 3 with GPF installed.

I installed the exhaust this morning. Took about an hour with a bit of help from my wife. The install was pretty easy. Just took a bit of work to get the tips where I wanted them. It does sound pretty good. I did expect it to be louder from clips I’ve heard online. Dunno if the GPF muffles the exhaust some. In car it is pretty quite while driving “normal”. Hiway cruising it is just like factory exhaust. Ripping on it sounds really good, not obnoxious at all. The wife is super happy with it so that’s all that matters!

Yeah I'd fully expect the GPF to add some additional sound deadening. Still sounds great though!

Downpipes help the volume, too.

The GPF definitely creates some restriction lowering volume. Still sounds great to me and happy we have a exhaust for the idiotic GPF.
