Demon Bolts

SPOHN

^ that's one reason I recommend against the swivel (reguardless of size) especially when it's not really needed. It flexes causing you to lose torque along with trying to apply force at a angle that can cause the socket not to stay on evenly.

Imagine trying to take a lug nut off at an angle.

Is there anyway to get at these bolts from underneath or is it necessary to go in from the hood?

SPOHN

Yes you have to go under the hood. But I have heard of people going threw the fender (at least on the drivers side) to have there torched off due to the bolt being stripped.

Hmm...I have a Dremmel...I wonder if I could just cut the damn thing off lol.

I wouldn't... I would keep soaking them all in pb blaster. The bolt is at an angle that is perfect to reach with 30" of extensions just put your socket set-up on the bolt and make sure it's at that same angle. I actually removed the strut tower brace, the post maf tubes and that really gives you a lot more room to see the bolt easily.

^ correct

Not to raise a dead thread but I am going to tackle this job sometime this morning. Any last words of advice?? I have all the necessary tools to do the job but was just wondering if there were any more tips or tricks I could apply.

PB blast the bolts for a bit if you can, use a 6 point socket set and try to not strip the bolts. Remove the CAI for better access and good luck! Yer gonna need it!!!

PB Blast the car now for tomorrow. Remove intakes. No reason at all you should need a swivel. Makes it that much worse. It's a straight shot. Six point socket (hopefully impact socket) and a two foot breaker bar helps a lot.

Got the bastards! Used Liquid Wrench instead of PB and the came off without a problem. Barely a creak out of the drivers side and the passenger side came off even easier. Slow and steady pressure was key here!

This was a new car with 1200 miles so I am sure that helped as people have said.

Could not figure out a way to fit my impact socket on the drivers side. Ended up using 1/2 universal and socket. Thanks for the advice guys. Couldn't have done this job without this forum!!

Never worked on an exhaust before or really any car before, and I had a clean run thanks to all the past failures lol and knowledge here.


what i did:

jack up car. spray bolts with PB Blaster. drive car around to heat up exhaust again. jack up car. spray bolt before using a 6 point deep impact socket and breaker bar. tighten bolt first to get it moving. go the other way and losen/remove bolt.

for the two bolts that had to be removed through the engine bay I used a breaker bar and only impact extensions, most of them were swivel extensions. didn't have to remove the Z1 post MAF tubes. for these bolts i placed the impact socket on the bolt first and from under the car and then had someone feed me the extensions so i knew it was flush and wouldn't strip and pressed into the breaker bar with one hand so it stayed flush as i was turning the breaker bar.

used so much force on the top two bolts that i fell once they loosened and wasn't sure what happened at first.

success, no broken bolts and a clean install thanks to the forum members here.
