my down pipe doesnt have at true surface so I have a nice exhaust leak. Could I wrap my downpipe in a fibgerglass sheet? What would happen if I actually fibgerglassed it?

what you mean by no true surface, cause that makes me think it doesnt exist.

 

im thinkin he means that the surface dont meet flush, i doubt fiberglass will work use jb weld

 

Break out the belt sander and the copperspray...

 

agreed^ if you dont have a belt sander a sanding block and some muscle does wonders.

 

dont even bother trying to wrap the manifold in fiberglass, i have done it before on a 2 stroke expansion chamber.... it does work but teh cloth is a bitch to work witha dn essentially it doenst have the same heat retaining characteristics as the espestis the header wrap is made of

just buy a roll off ebay for liek 20 bucks
