Exhaust Rattle

[Eric K]

Buy 43 x 3.5 Viton o-rings. They seal better and last longer.

Installation can be difficult, especially if your pipe has been bent. First off, don't put grease inside the o-ring groove or the o-ring tends to pop out of the groove during installation. Just grease the outside of the o-ring after you put it in the flange groove and grease the inside of the pipe flange. Then push the pipe on far enough to get the springs on and let the springs pull it up.

My 12 300 had issues. The springs were not very tight and would rattle to be... So I took a piece of copper and machined an .125" spacer to go between the pipe and the flange on the cylinder. Worked great. No more rattle.

ok so it seems like i should have looked closer, rattle is from the pipe bent against the frame and rattling there!
So will try to bend it out this evening and failing that i may try the spacer option to solve 2 problems in one go!

SteveV , to clarify, this spacer you made does it fit on the end of the manifold, inside the exhaust?

yes, that is correct.

here is a of what I machined. .125" thickness seemed to work for me.
