i got a new exhaust today and im havin a hard time getting the OEM cat bolts off... i need to replace them, but what size,length,thread do i need?! its got a spring thing too.. so do i need a special type and where can i get them?!


its a 98 civic coupe, installing a GReddy SP2 exhaust

 

why did you make 3 posts? go to the dealer for the springs. really anybolt that will fit in there will work. i think its a 10 mm

 

even better...why did you make 5 posts..i don't feel like helping now
