See if Remflex makes a collector gasket for your model. They are a compressible graphite type gasket and if you don't overtighten them to Hell, they can eat up little imperfections in the collector mating surfaces. The other possibility might be Wurth exhaust paste.

The other problem I ran into when installing headers was heat-cycling bolt stretch. I followed the Gibson Performance Exhaust recommendation of retorquing after the first drive, first full day, and first week and never had a problem after that.

I hate exhaust leaks.

I'm sure sitting at the paint shop for several years didnt help. Collector gasket is missing a piece at the bottom. I could feel it with my hand. No biggie. Hooker Super Comp headers, X pipe, and Flowmaster 40's! Love that sound! Especially grabbing another gear at 6500 rpm!

I am a Flowmaster fan as well! I have 3 inch super 44's with no cats or resonators on my 2013 Boss 302! It sounds incredible with no drone or all of that high pitched popping and snapping that all of these so called new tech high dollar mufflers, which are no more than glasspacks in disguise have! They also sound killer at 7500 rpm's as well! Here's a little sample.
