Okay guys and gals I got my FMF Gnarly & Turbine Core 2 S/A last night from UPS at 9pm. I'm going to put it on some time this week and was wondering if anybody has some tips they would like to share? I was wondering a couple of things can you re-use the pipe spring? and is there a gasket or something between the stock chamber and stock spark arrester that I need to reuse? I know I read a long time ago to just bolt up loosely to get a good fit then tighten down. I'm just trying to save some headaches while in the garage.
