Help and questions about installing cat-back exhaust...

Synchros shot? Weird noises while shifting? Not sure what needs to be replaced?

I use it whenever working on anything exhaust related, makes things go smoother the next time you do it.
when i did my front brakes on my truck i coated every bolt i had to take off with anti seize before i put it back on. i will never go through that much shit to do a brake job again, so help me god

PB Blaster is far more effective.

50/50 mix of ATF and acetone is the best rust penetrant known to man. it demolishes PBblaster and embarrases WD40 in lab testing of torque required to break loose a lab rusted bolt

what i did after getting tired of working with shitty rusted bolts, i went and got some grade 8 bolts from the hardware store. now i just airgun them on and off, dont gotta worry about snapping a 3/8 thick grade 8 bolt

Where were you when my fuel filter wouldn't let go of my nuts? Image

there are test results on the interwebz somewhere, ofcourse i didnt CTRL D them. it was something like 500ftlb to break loose a plain bolt, 300 with WD40, 250 with PBBlaster, 200 with some rare expensive shit and 50, yes 50 ftlb with acetone/atf mix

i might have to buy a can of acetone and a bottle of ATF and keep a empty coffee can around next time i work on anything wiht rusty bolts

here it is, apparently googling 'rust penetrant test results' gives you what your looking for. amazing :headscratch:

I spent a couple weeks crawling under my truck once a day to spray PB Blaster, spray cold spray (upside-down canned air), hit my fuel filter nuts with a hammer, and try to loosen them...I finally gave up and took a chance with the dremel, notching the nuts to relieve some of their pressure. I wonder if I would have gotten it done in a day using the acetone/ATF mix.

Just so my small brain can grasp this... ATF = automatic transmission fluid?

Yes. Slushboxes have to be useful for something.
The ATF works best when fresh from the car. So go kill an autotragic and drain its blood :twisted:

I'm excited too, but I'd rather wait if it means not dealing with rusty fasteners.
