Hi im new to this forum i have a 00 ZX7R that i bought last year with 1800 miles on it now i have 5500 on it and have the mod bug. So far i have added Metzler M3 tires and the 520 conversion going down one tooth on the front. I just bought a slip on pipe and was wondering how to install it when it comes in. It looks like i have to cut the old one off i think its welded on am i wrong? Any help would be apriciated.
