I had 1986 GXL that I installed the RB header and presilencer, and it did loose some low end grunt in the low RPM's. But on the high RPM's she really gained the power. I am sure that you will find other threads if you look at some of the older posts. Good luck!

I noticed a slight loss in power when I went from a 2" dual cat-back to a 2.5" dual cat-back. I could actually feel that it wasn't pulling as hard. (this was when I was still N/A )
