V6 need a quieter exhaust recommendation

jtsmith · 02-05-2026, 08:10 AM

I bought a 2020 V6 Auto with 20k miles on it. It has Flowmaster 409s on it and the drone is too annoying for long trips. I've been watching FB for someone with a factory exhaust with no luck. Is there an aftermarket muffle anyone can recommend that will make it sound more like the stock muffler?

Why not buy a used stock exhaust cheap and put it back on? People will likely give their replaced stock suitcase away for free or near free, then an exhaust shop can just weld it back.

I'd happily do that. I haven't found one nearby.

Looks like he’s been looking on Facebook with no luck. Try eBay. I see one with the duel tips and one with the quad tips on there for the v6

Sorry you’re not having much luck finding an OEM exhaust on FB marketplace. I don’t see any for sale on Camaro6 either. The Borla S-Type axle-back seems to be one of the most popular options that members buy. Maybe you’ll get lucky and find a President’s Day sale.

Ironically when i got my car it was in this same situation. Single chamber flowmasters made this drone above 63mph. It was so bad i could feel it in my teeth.
I found a NPP muffler with no valves on marketplace for $100. Best hundred bucks ive ever spent.
