Hey all! I’m slowly working my way through my pitts and working on test fitting the exhaust. This 4-1 system came with my project and seems to fit awesome but there are no tabs to hold the slip joints together with springs or bolts like the raven setup. Is there anyone that could help me identify what system this is and if I should weld tabs on at the slip joints? Or possibly some clamps? The hanger at the collector seems to keep everything very tight but i’ll most likely be adding spring tabs for peace of mind if anything.
