Hey guys. I found a good deal on Blitz Single Exhaust Axle (Y pipe) back. Before I jump in to this, I'd like to know Am I losing power because of single exit if not gaining power? And what else do I need to make it fit into my G because it comes from a Z. I love how it sounds but the only thing I have to worry about is the power. So please let me know. Thanks a bunch guys.
