## Description

J-B Weld MufflerSeal Muffler Cement Plastic Tube 6 oz. (37906)

Review: Before paying big bucks for a new muffler a little of this may be all that you need! - This stuff worked great! If you have the luxury of a little extra time or a heated garage or heat gun I’d take advantage of it because it does take more time than one might think for it to cure. I pretty much used a whole tube (smaller size order option) but I also laid it on thick around the collar area where the muffler meets the exhaust. I live in the northeast so it’s been cold and I wanted the extra strength for the long winter complete with caustic road salts, moisture and frost heaves. It was a great fix to get me over the hump until spring! J-B Weld is a great company with great products!
Review: Used on 3in 94 k1500 exhaust, worked great. 350sbc - Worked great for my application however, it cracks on moving joints. Still sealed my exhaust very nicely.
