Hey Guys! I've been reading threads for some time now, great advice! I'm looking to make my truck sound better, but don't have the cash for a catback. So I was going to change out the muffler, to a Magnaflow or a Flowmaster like many on the Forumz have. I want my truck to sound meaner. The stock muffler on the truck is huge, and my understanding is that the bigger the muffler, the quieter it will be. So that leads me to believe that if I use the same size from Magnaflow, I will be disappointed and will have wasted my time and $$. Can anybody give me some guidance here? Will a smaller size be bad for the truck? Will the big muffler sound better from Flowmaster? I think I've read that the Magnaflow is better on a performance standpoint, which I would prefer, but the guy I talked to at Magnaflow told me that basically on a 1-10, 5 being stock, switching to a Magnaflow in the same size would be like a 6 to 6-1/2...that's not the results I'm looking for! Help!
