I'm changing my exhaust from factory to a 3" ebay N1 style catback on my 98RS-T. I was wondering if you guys have any tips or tricks to get these stupid catalytic converter bolts/nuts out on the muffler side. The last one I had done the muffler shop heated and wrenched them off. I don't have access to a torch that gets hot enough to do that, and I also don't have the end section,third section w/ muffler, of the factory system to drive there. (I live in virginia and that's a no-no, 20 exhaust tickets so far).

So far I've tried PB Blaster, impact, hella long cheater bar, cheap torch... just about everything I could think to no avail. I really don't want to cut them off and drill the rest out, but if that's my only option then I have no choice. Any help is greatly appreciated.

ah... turbo. I love the turbo, the boost, the speed, the sound.
and its all better when you do it yourself. cheaper too.

Just keep spraying PB blaster on it and let it soak.

I would also tap it a few times in between soaking. Spray it, let it soak a few min, and tap it with a hammer or small sledge. Then try to break her loose.

I just did this, I ended up using my cutoff wheel to notch out the flange on the cat and I used oversized flare head bolts and nuts to get it all tightened down.

Just saw them off and replace with new. I don't even bother fucking with them at all anymore.

Step one: cut or blow bolts off.

Thanks for the input guys. Looks like I'll be getting some new bolts.
