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

 

short-term memory loss anyone?

 

If you got to a Autozone or Napa they have a help Section that has the Exhaust Bolts with the Springs.... Getting them off I had trouble on my Integra I used a Dremel tool or a Grinder and grind the Nut off... Or Try using WD40 or other penetrating crap... Be Careful removing those I actually was using 2 wrenches and broke the nut and CRACKED my Hand

 

it should be okay to take off. use some wd-40, a long ratchet for more torque and a combo wrench on the other side. works everytime for me
