what i mean is to remove the exhaust sleeve insert and use this puddy for a new sleeve. kinda like using JB weld to fill and shape the bowl in the intake runner. Theres a few people that have removed the sleeves and had an aluminum one thats better shaped.

very true. ceramic paint does ware off. but im wondering if it will hold up because its a puddy and will be much thicker than spray on paint.


now i think the problem is having it hot for extened periods of time it could cause problems. especially on a road race car or on a long drive in a street car. maybe losing its bond and coming loose due to expansion. this could be solved using roll pins like the stock one does. i doubt the actual puddy would melt. but my intentions for this are purely 1/4 mile drag racing. where the car is running for a minute, burn out, stage, run the 1/4 and get back in line. thats maybe 3 minutes of run time. so im thinking it would be OK.

if used in the exhaust to form a sleeve, the worst that would happen is it comes loose. it can not be sucked into the motor and could not cause and major damage. just remove the header and its gone. also, JB weld and Devcon are only rated at 500* and they hold up well in the intake side. im thinking somethings with 2400* wouldnt do to bad on the exhaust side.
