I was all set to buy a Yoshimura RS-4 Titanium exhaust for my 2011 CRF250 but after looking at the cracks in my Lightspeed bash guard I think I would be better suited to their stainless system. I am pretty sure they are the same exhaust except for the materials they are made out of, but I was just wondering if anyone could could tell me if there is any difference (apart from the weight) between the RS-4 Titanium/Carbon Full System and the RS-4 Stainless/Aluminum Full System? And Is there any difference in power between the two systems? I don't want to buy the stainless system only to find out that the Titanium makes more power? Thanks for you help.
