If you're looking for a stock replacement without the stock price, you may just want to go with a Walker. I can't attest for what they are making now, but 25 years ago when I worked at the local Parts Hut, a high quality OEM replacement was Walker, and it seemed to corner the market on non-muffler shop mufflers (muffler shops carry their own brand). It was then (and I'm guessing now) a high quality alternative. They hold up well, they were quiet as stock, but usually performed better than stock, as OEM muffler quality usually wasn't that good. I noticed that dynomax rates all their own mufflers, walker, and old-school performance thrush (I'm guessing they own all three) on a scale from most quiet, to most performance: goodhttp://

They have one muffler that is so new it isn't on this scale, wondering if anyone has experience with the new Dynomax VT? The VT stands for valve technology; it has a butterfly valve that has a spring that holds it lightly closed. The idea is to have a quiet idle, a quiet cruising speed, but will open up when the throttle goes down.

I'm thinking of using this along with the SuperTrapp. Even though I was considering running just the glasspacks, I am not that big a fan of exhaust blasting. But I do like it to open up and it's nice to hear the right tone at that point.

The SuperTrapps would just be there for looks, exhaust tone, a way to tone down the vehicle for the DMV, and most importantly, a spark arrestor. In Colorado, it doesn't take much to start a forest fire. Spark arrestors should always be used here on any straight-thru exhaust design, especially on off-road vehicles. They are always so hard on the dirtbikers, but many fires have been started here by sparks exiting SUVs.
