i can't get the bolts off by the cat they jus wont come off how should i get um off and wut sizes exactly r the bolts the sizes in the forum like don't fit liek they r 2 diffterent size nuts like on the cat end

 

go to autozone and get some liquid wrench it will help a lot. as for the bolts i reused my bolts and they worked just fine, but you could go to the stealership and buy two new cat bolts?

 

i couldnt get mine off either. I bought liquid wrench and that still didnt do the trick. So I just put one bolt in the front section and one in the middle section and took it o meineke and gave the guy there 5 bucks and he took them off with the air tools.

 

but then if he jus took it off did u have him put the new 1 on also or how did u work that cuz u can't drive it without the y-pipe

 

Cough, Get air tools, Cough.

Actually I did this install before I had airtools. I did the same as MaXAnDy. I went to a local shop and they cracked off the bolts. I then drove home. If you leave the Y-Pipe on the manifold it won't be a problem to drive without the rest of the exhaust for a few miles. Lucky for me, my exhaust shop is .1 miles away.

 

ummm try pb blaster......

 

Yea i just told him to put one of them on, but lightly so i just took it off when i got home.

 

Listen to maxima98vspec...PB Blaster is da bomb. You can get it at your local Walmart. Spray that magical elixer on all of the bolts and let it soak for ~15min then spray it again and wait another ~15min. You should have no problem in taking the bolts off now. Remember, struggling is half the fun of modding. It make completion all the more sweet.

 

i about wrenched my arm off tryin lol

 

14mm socket with regular wrench will do the job, but you must:

1. get wd40
2. spray and pray
3. pull like a ****

good luck

 

my pi$$ works better than wd-40 $hit, i went out and got some PB blaster and never had thoes problems. just soak it and wait. or u can use wd-40 and end up drilling the Fuccers out like i did.....

 

do u think that liek midas will install the whole thing for me its cold out and i don't wanna do it in my cold garage

 

wut r the 2 rings that come wit the y-pipe were do they go

 

those are the exhaust gasket. you should put them in between the y-pipe and the header (where the connect). even though those rings look kinda ghetto, but they work really well.

you should have 3 though, 2 for the headers and 1 for the cat. if you don't go to nissan dealership and pick one up. i don't have the exact part number but just ask for maxima exhaust gasket. (i think it was $4-5). if you dont' get it...enjoy the leackage

 

I just installed my y pipe and due to 120k miles in chicago and the wonderful salt I ended up cutting off the heads of the bolt to get the Y off. Then I took liquid wrench to the studs left it for an hour hten took a propane torch to heat up the metal around the bolt so it expanded a little. Grabbed vise grips and just pulled one of the studs right out. Other one I had to drill out. I love salt/rust.

 

Midas won't be very pleased with you but they might do it. Go to your local exhaust shop and have em toss it on. With a lift this can be done in 20 minutes.

 

yea i had to drill 2 bolts out where my stock muffler connects to the stock b pipe, cause one of the bolts broke off and had a exhaust leak, i spent like hour and a half to drill them out and my car only had 50k miles.....dam utah

 

yeah my car has 58,000 miles in chicago weather, acutally it was in georgia it first 30,000 miles. I had to take off the whole exhaust to get those freaken bolts off. And I was at my friends garage with air tools.

 

I snapped a stud on my cat... soooo don't do that. Work in pb blaster for like 3 days, then try it with an impact

 

looks like i'm gonna have fun tomorrow with a jersey driven car that has 123K miles on it. . .
