i have dual exhaust from the headers back. looks and sounds great from the outside, but on long trips, the extra noise becomes tiring.
hell, i'd love to find someone in the area that was willing to swap their stock exhaust for mine. i'd prefer to hear my music at a more comfortable volume. guess i'm getting old, turned 26 last week.
I had the same noise issue, the resonators toned it down A LOT.
I'd go to resonator tips as a last resort, most don't seem to last in the long run.
I should get around to a sound clip one of these days...
