2500 6.4 - Flowmaster 817709 American Thunder Exhaust Kit

[62Blazer]

Anybody have the Flowmaster 817709 American Thunder exhaust kit on their 2500 6.4 Ram? One popped up on Facebook marketplace locally. Never installed and about half the price as new.

Doesn't seem like it's supposed to be a super loud kit, which I like. Main concern is drone on the freeway, especially when pulling a trailer. I can deal with drone and exhaust noise on short trips but I do several long trips a year pulling a smaller trailer with my SxS on it and a lot of exhaust drone gets to me after 3-5 hours in the cab! Guessing I'm getting older, but would like to have the truck sound decent.

So I had my 2009 ram 1500 with no muffler. I loved the way it sounded. Then we bought a travel trailer and it was very loud. Too loud for long trips. Now I got a 2019 ram 2500 6.4 hemi and I’m going to leave it stock. The 1500 was very fatiguing on longs trips. I think the 6.4 sounds really good stock.

I never had the complete kit, but I did have the 50HD muffler on my 1500 for a short stint. Nice sounding muffler and not overbearing at all. I had no drone with mine. One of my favorite mufflers for sound quality and low interior cab noise.

I have the flow master American Thunder on my 1500 5.7. It sounds great, not too loud, only subtle drone when MDS kicks in, otherwise no drone at all.

Picking up this kit tonight. Supposedly never installed and the guy will take less than half of what it costs new.
