Bb exhaust
I installed a Billy Boat Fusion exhaust on my 06 m6 SPD about six months ago. I love this system but had a little too much noise in the cabin. I was told by BB and others that a cross over would do away with 75 percent of this noise. Another $425.00 and I now have the BB cross over installed. Truthfully, it did not do a whole bunch for the noise BUT you would not believe the performance gain!! had I not done it myself I would never have believed it. HP and torque are unbelievable. I have a good friend with a 07 that is always messing around with me on the road. I now leave him far behind easily. He has ordered the entire exhaust system! Why doesn't GM install systems like this?

Are you talking about an X-pipe?
My 08' came with and X-pipe and NPP, so GM does offer an exhaust like that. I believe the B+B is little lighter than the NPP though, and the B+B is polished. That's a nice touch!

I could be wrong but I believe the c6 05 thru 10 came with a "H" type crossover. Mine did. The BB is a totally different design. I personally have not seen the stock pipe on a 08.
