I'm trying to replace my exhaust (Cat back) and the bolts where the flange from the resonator side bolts to the Cat is stuck...rusted together. I don't have the new exhaust yet, so I can't tell how the 2 pieces bolt together. Is the stud on the resonator side and just screwed in to the Cat side or vice versa? I only have one bolt and it's on the resonator side. I'm thinking the best bet is to cut or torch it off, but I don't want to screw up the flange on the Cat side since I will need to reuse this. Can't believe how rusted out this all is, and it's only a 2K1,,,,kinda ridiculous if you ask me. Anyway, all help is appreciated.

Thanks

should be a bolt w/ washer n nut, i know when i replaced my y-pipe n cat they had to torch off the nuts, but my stuff came with new hardware and flanges.

 

the best thing to do, if you're going to install the exhaust, is to go to a shop, have them cut the old bolts, and just put new ones on that you can remove easily when you do the catback.

Pretty much everyone has to do that....

 

3 ways you have:
torch it and use regular sockets
torch it and use turbo sockets
air hammer the nut without touching the stud/rrethread the stud

worst comes to worst, cut off the nut and stud and torch the remaining of the stud in the cat and twist it out. then put a new stud into the cat
