I've got a pretty popular setup on my 2nd gen. Two 2" pipes back to a collector near the rear axle into a single 3" through a Dynomax Ultra-Flo. Last time out at Mid-Ohio I had high score in my group at around 103db. "Turn-away" is on the way. Don't know how you'll make 93db without a good muffler.
