Well I had a window to install Friday afternoon. Aside from measuring twice and cutting twice the extension pipe before the muffler, this was a good install. The sound is mellow but pronounced. It's great so far. On the highway, I think I have more power than with the Dyno max, and it's actually quieter over 2000. One thing I did was reuse the old tip with a step band clamp. The supplied tip is just too nice for around here, and I'm afraid it'll get taken, and I don't want to tack it on. Thanks again for all the replies and to Geno's for quick and professional service!
