dude had the same problem. They wanted 20 bucks for a strap, phuck that!! Went to home depot and got the metal adjustable pipe straps that look almost identical for 4 bucks a piece!! Ive had em on for more than 6 months wit no issues!!
I'll check when I get home tonight. I know I have # 1,2,4,5. Your welcome to have the extra parts I have. When I put the race pipe on I just bought all new mounting hardware. Just need to double check on whats there
