Yeah I'm straight piped, have been since I first deleted and tuned it. It is definitely quieter now with the compound kit but I like the tone better I think.
When I had twins on my LBZ, I ran straight 5" exhaust, and I loved it. When I went back to the stock turbo, the drone drove me crazy, and I had to put a muffler on it to tone it down. Twins definitely kill some noise.
