i just got a megan ypipe and testpipes today and i jacked my car up to see if any of my bolts are striped. I hate when i started on the car starting to take bolts out and suddenly see one of the bolt was striped even before i touched it and end up putting everything back on and take em to the shop.
anywayz, all of my bolts that are on the 2 entrance flange of my Y pipe are striped. i tried to torque it with my 17mm socket but it would turn and stripe em more. i asked the shop to check it out and asked the price to install ypipe and testpipes for me they gave me price of $200cash.
here is my first question, how can i take that bolt out? with just tools, without using any mass heating process.. i only have basic mechanic tools on me.

second question, how the hell am i supposed to take out the cat? the upper bolts are facing all different way and there is no way i can fit my hand and loosen it up. when i actually looked at the 1bolt facing at me and 2 bolts facing the engine i was like WTF. no room too lol.... i'm planning to work on it this coming saturday. i know bunch of you guys have taken out stock cat's rusty bolt out at home...
please help me out, i don't want to spend $200 for something that i could do it myself at home.. only if the bolts weren't striped

PLEASE LEAVE ME COMMENTS AND SUGGESTIONSSSSSSSSSSSSSSSS

Removing a cat?

Get a mean dog!

 

...

Buy 3/8's Extensions, you can reach a lot from the top using about 2.5-3 feet of extensions and a swivel.

 

ohh i gotta do it from the engine bay, i see and LOL on 3feet of extensions lol only got 2 3/8's extensions haha

 

i think i need to buy bolt-out socket set from craftsman to remove the striped nuts.. i guess its worth having more then spending $200 to let someone do it on the lift right

 

youtube 350z cat removal. there is a step by step video.

the remove those bolts, drench them in Liquid Wrench, then wipe them off, then get some grip pliers and grip and turn.

 

do you think liquid wrenchin on the nut and using the grip plier to remove with my strength would make the nut unscrewed?
i guess i gotta give it a try. thank you
can you link me that diy? i can't find the video on youtube.. thanks again!!

 

ok i think i got the diy on the youtube, its the one that installs high flow cat on 350z right?

 

liquid wrench is a life saver. Seriously cut down the timing on my exhaust install. Just sprayed it on there, let it marinate for a little bit and with a little power took the bolts out.

 

really? it works that good? does that liquid wrench makes the nut really dry? what does it do

 

google it

 

i bought the pb blaster and i took out 3 striped bolts on the ypipe but one doesn't come off. it got even more rounded lol.. i guess i gotta go grab a bolt-out socket sets..

 

i got the last striped nut out with the 14mm bolt-out socket..haha just put on megan ypipe and took a test drive, not a big difference but little bit deeper tone of exhaust. i gotta put testpipes on saturday! thanks for all your help guys

 

Why didnt you just wait to install both?

If you have a crush type gasket your going to have to install a new one.
