i just bought a tsudo n1 catback just came in the mail today. Heres the problem, for the past three day i have been trying to break free the nuts connected to the downpipe. there just not budging. ive been under there with PB Blaster openend's a box wrench and a propane torch but nothing is working. I would perfer not to have to go at it with a grinder but if i have to i will. can anybody help me with this?

 

air tools?

 

How long have you had it on the car, the stock one? I had mine on for a year and a half and it was a bitch to get off. You just gotta get at it from the right angle and torque the **** out of it. It worked for us but it took 2 decent sized guys to get it off. Good luck, you're gonna love the Tsudo.

 

gunna try air tools tomorrow hopefully.

its an 07 with 52,000 on it and when i first started it was just a ball of rust now you can at least see the bolt. ive been trying o get it red hot but its just not getting that hot

 

success i have broken them free

 

even you did it already. Ive done this 2 ways. on my balt i sprayed zep 45 (a penetrating/lube spray) on the bolts a week before i got my cat back. broke em loose by the time the exhaust got to my house.

second way which i had to do on my buddies lancer, is i grinded the bolts out without damaging the flange. went out and bought new bolts/nuts and installed them with the catback.

hope this helps future people with this problem.

 

Congrats on freeing it up. Lol.

 

thanks you were right i got the wrench on and i couldent move it so i put my foot on the bottom of the car and just turn the crap out of it

 

Oh yeah. We tried getting that **** loose at first, nothing. So then we decided to cut the exhaust at the axle, then we had room to wiggle it so while I was going at the bolts with a wrench he was wiggling it up and down to get it loose. It took FOREVER. Burned through 3 dremel bits and broke a sawzall blade just getting the damn pipe cut too.
