I recently blew a baffle in one of the cheap econo mufflers on my tow rig. Which is a 1984 Chevy c30 powered by a 454 auto. Since, mileage fell off a bit and I'm sure it's restricting flow. Gotta change both mufflers.
Onto my question, what free flowing mufflers have you had success with? Oh, my actual problem is it MUST BE QUIET. I pull my stock trailer with this truck and I Know 2 chamber flowmasters would be brutal in the trailer. I've never needed a quiet free flowing muffler before. Our area doesn't do emissions or vehicle inspections so anything goes. Where as I know in some areas, even race tracks have noise restrictions.
I've read up a lot, but prefer first hand knowledge when available. So if anyone's had to deal with this challenge, share your experience. Even if its a fail.
