Rpeka, I haven't done this on the Camaro, but I had long tubes and no cats on my 2005 GTO. I have found that the cars with the mufflers at the rear do not have that much of an interior sound difference when installing longtubes. My GTO was very loud on the outside, but inside the car it was very tolerable. I took my wife on a 5 hour drive in the GTO and she didn't complain inthe least about the noise. In constrast, my 68 Camaro and my old 1987 Aerocoupe Monte Carlo with the mufflers under the rear floor pan were much louder inside the car. It may also have something to do with how well they insulate the cars these days.
Bottom Line: Don't let the worry of increased noise keep you from doing this.
