[QUOTE="Creedence85, post: 167364, member: 4346"] Hey Wayne, glad that the install worked out for you. I had similar trouble fitting the pipes, but I tried pre fitting before installing, and I just carefully expanded the axle pipes with vice grips. I noticed the same thing with the sound too, louder when cold and then quiets down when warm. I drove the car the day I installed, it was about 11:30pm at night when I finished (I had trouble getting the rear sway bar reattached and torqued properly so took a break), and when I fired it up I was trying to keep and open mind but wondered if it was going to be too loud. After a few hundred KMs of driving it started to break in nicely, and now with a couple thousand it's really breaking in nice. I installed it last Sept. and this spring around Apr. I started to notice that it's not as loud when cold, the 2000-2500 KM resonance is nearly gone, and when warm is has a deep tone but the bark has mellowed, so I don't feel like I'm ruining my neighbour's day. I think the 2000 RPM drone you're referring to is kind of like the 2000-2500 RPM resonance that I referred to. I find most of that is nearly gone now. To be fair I sound insulated the rear cargo area before installing the exhaust, then sound insulated behind the seats and the doors this spring, so that might help with some of that. You're going to love the Rocky Mountain Cruise and that should help it break in further. On the highway it has a nice rumble but no drone. The down rev pops when off throttle on the flat or down hill are fun, and the revup tone is great. As you rev up, the tone and pitch changes, but it doesn't get much louder which I really like.
