Stuck bolt on Exhaust.... frustrated!

--------------------------------------------------------------------------------

So I am trying to get my new Nismo exhaust installed tonight on my Altima 3.5SE, and I have run into a roadblock.

One of the nuts connecting what looks like the cat to the main pipe with the resonator on it. I got one of them off, but while trying to break it loose, the nut started rounding off. I can't get it off! I used PB Blaster beforehand, but to no avail.

I called a couple of muffler shops, and asked them what they would charge to break that sucker off, and they said $30-100. Of course some people here have had entire systems installed for less than $100!

I am going to try to get a nut splitter from autozone and try to break it off tonight.

I wanted to have it in tonight.

Has anyone ever tried a nut splitter??

 

Here are a couple of pics, of the new altima and the exhaust....someone help me! I need to hear this VQ roar tonight!!

 

drill a hole through the bolt

 

I guess I mistitled this thread, it is a stuck nut.

 

take an angle grinder to it man.....

 

Here is what I did tonight, since I couldn't get my exhaust in....I finished my wheels, and installed my SE-R Tails. That was fun, but not as satisfying as getting the exhaust in.

 

Looks Great! Try a torch, it usually does the trick, but use common sense if you use this idea. I take no reponsability if you screw something up, or hurt yourself!

 

i would just use a grinder and cut the ****er off, GL and what a sexy ALTIMA!!!

 

What I did was dremeled off both sides thats stuck out past the flange, then drilled out the middle, very easy, just time consuming.

 

they sell sockets designed to remove stripped nuts. We use them to take lug nuts and locks off demo derby cars. They make all sizes though. Check autozone or pepboys. I can't remember where we got them


here's an idea of what I'm talking about...

is it tricky to use nut splitter for those nuts?

 

Heat that sucker up until it glows cherry red, that nut will spin off like butter.

 

Thread's almost 4 years old

 

is it that simply? because i can use a 14oz propane can and torch the sucker and vise-grip it off.

 

Always try a nut splitter first. You can get it at harbor freight for like 4.99. If that doesnt work I use mapp gas to heat up the nut and whack the **** outta it with a cold chisel. I got a nice one with a hand guard at lowes 14.99. Its never failed me.

 

i'll give it shot. if it doesn't work, then i am heading to a shop.

 

They make proper extractors. I have a snapon set.

+1 for heat...just watch any brake lines or gas lines if the exhaust is still on the vehicle.

Took a stuck bleed valve out of a Jeep caliper with a road flare & vise grips one time, good one for the mcgiver file...I had just about rounded it off too.

 

old thread

but yeah heat the bolt up and turn it slowly

 

WOW....he has been working on his exhaust for a LOOOOONG time (2007) lol

 

Well for anyone in the future who has this issue and wants to hear about a worst case scenario: my bolts were completely rusted off and there was nothing left but studs, nothing I could even put a wrench or a socket on ... I had to cut the whole piece off with a oxyacetylene torch, then have a shop weld a new flange on my cat!
