okay quick qeustion i have an exhaust leak were the pipe meets the header and i tried to re clamp but i cant seem to get it to go away my q is will this harm my bike it backfires alot but is it still good to ride

 

High temp. rvt sealant/gasket maker from an auto parts store will fix the leak. Spread it on the inside where the pipes join and let it dry, you can then rub some into the gap where the pipes connect after getting it back together for a good seal. Dont ride it until it can dry completely. I had mild backfire or sputtering on my last bike after putting on a slip on. I think a pc III will fix that, but I doubt if it will do any short time engine damage without one.
