RE: Exhaust
Stock 6-speed mufflers are a straight through design. At fitrst, I replaced those with Flowmasters and left the rear resonators in place. The sound was not much different at all. Same tone, same volume. Then I cut the rear resonators off. WOO-HOO! That did it!
If I was to do it again, I would remove the rear resonators FIRST and see what the stock front mufflers sound like. I would be willing to bet it would be even louder then the Flowmasters because the Flowmasters have all those internal baffles inside to redirect the flow. As I said before, the stock mufflers are straight through...no baffles.
