How do you keep your stock exhaust on the collector?

[Brainchild]

This thread is just in time.I have the same problem with the pipes coming loose.Nothing seems to help either.I'm changing exhaust in a few days,so I'll try hanging it from trans.
Seems the standars trucks are worse than the automatic trucks too.I did notice the problem got better when I changed motormounts.

If the only problem is the nuts loosening, try Stage8 fasteners. What is the manifold collector stud size? 3/8 bolt x 16 thread? Anyway, Stage8 sold me the nuts with their clip on piece that will hit the pipe before allowing the nut to back off the studs in my Rams Horn manifolds.

I remember ole Stacy on Trucks showing a product on his show one time (usually I dismiss the products as wildly out of reach) that I thought was interesting.

They were these clamps that go around your collectors and essentially vice the thing together. It still used 3 bolts, but they were contained in a housing that provided uniform compression to the collector. Seemed like with the right bolts you could tighten those things down and they'd never leak.

I don't remember the vendor though...anyone remember what I'm talking about?

Were those for headers? In his first post, the thread starter said he has the stock set-up, i.e. manifolds. I know what you're talking about as far as header collectors go. Don't remember a vendor, either.

Ah they may have been for headers....but I imagine if you could chase down the vendor they may have a setup for manifolds as well! It would be smart on their part if they really wanted to help a hot-rodder out.

Again, they work like a clamp. They fit over the collector junction and provide uniform force over the entire connection rather than three points. Damn, I wish I could remember the vendor's name....

I had the same problem a few years back.I had a new exhaust installed from the manifolds back and my passenger side pipe would work loose no matter how tight I cranked on it.I finally found out the donut was slowly shifting around due to a missing piece.Pull the pipes down and make sure there is something that will hold the donut in place.My driver side manifold had something to keep it in place but the passenger didn't.
