You can purchase the bolts here (bottom of the page):

I once used a bolt from Home Depot and it worked fine (I forget what size I ended up using).
My current mid-pipe came with basic bolts/nuts for both sides and its been running fine.
No exhaust leaks.

You know I thought about going to Home Depot but I didn’t know what size to get. Thanks a lot Jon316G

pull the rubber holder/anti-vibration thingy -- wd40 works wonders

pull the plug for the O2 sensor

remove the forward bracket (remove 3 bolts, loosen the 4th and swivel it out of the way) that cross cuts underneath the midpipe.

pry (I used a 17mm wrench) the foreward joint away and downward from the manifold pipe after removing the bolts from the fore and aft ends of the midpipe.

A little tug forward and the pipe will come right out.

and then (the step that makes this post ontopic) using a mallet to tap each of the 3 forward bolts straight out. They're flanged on the stock assembly. a couple good whacks and each should pop right out.

guess it's obvious what I just finished doing

I find using low grade plated bolts is the best for exhaust...if you go too high grade they tend to be a real bitch to get off...the cheap ones you can over tighten and get out real easy.......try that with a Grade 8 bolt

the best thing to do is put high temp anti-seize on the threads early on and torque them properly, then you won't ever have an issue

Buy stainless steel bolts. That way they won't rust and they take the heat much better. Easier to remove in the future should the need arise.

stainless steel galls easy and will still have issues as hot as the rotary runs, just use anti-sieze, never had a problem, still on the OE bolts and have had everything on and of so many times it isn't even funny, the main thing is I used anti-seize the first time I took things apart early on

Thing is i bought a midpipe and it didnt come with those studs. So i either have to remove the stock studs or buy one from somewhere. Wonder why i didnt get any studs/nuts , what a way to make things more complicated -_-. But JEEZE those studs are REALLY stuck in there. Oh and is it just me or are the nuts all different sizes on the midpipe? Nut sizes are 14mm , 15mm and 17mm i believe , is this normal?

On a similar subject, anyone know offhand what size the flanges on either end are? Going to be making a custom exhaust systme and would like it all to be interchangable with stock parts.
