Guys, I have been running them for two seasons and I love them. When I first put on my Rush pipes last year they sounded great up until about 3000rpm. That is when the droning sound would start. I ignored it at first and then I broke down and got the Torq Loopz, because guys said that they eliminate the droning. They do as advertised. My bike now sounds like a Ferrari when I take off and quiets down significantly when I level out my speed. I have been up to 85mph for extended amount of time without any issues.
I have not had any issues with them not sealing. I suspect that that is from guys that don't clamp the pipes at the joints first before they mount them to exhaust hanger. I have had them off and on a few times without any issues. Mine have not leaked as of yet.
The main thing to remember when installing them is not to tighten anything up tight until you have everything in place. The hardest thing for me was to make sure that the exhaust shields were in the right position. Also, make sure that the end of the pipes line up even. I was lucky with the right side. Everything lined up perfectly. The left side had me saying a few colourful words. I was using aftermarket pipes being held up by brackets that I made myself. Getting them lined up was a bit of a bitch. Mainly because I bolted everything up tight.

Robert, the crossover pipe really isn't needed. I know Honda put it there, but it's only purpose is to even the exhaust pressure for a smoother sound. When I accelerate I can hear each side and I prefer that sound. I would think that the guys at Torque Master Pipes would have included a cross over if one was needed. Also, I have not noticed any decline in power because of it. On the contrary, my bike seems to have more pick up and go, but that might be the Rush pipes, or my wishful thinking.
