Hey guys finishing up my build & wandering if poly motor mounts will be ok. Running truck manis & a chasis braced s475 with flex joints on the hotside & a bumper exit down pipe. Any problems melting the polys that anyone has seen? Thanks!

never seen any problems with polys except people that try to run them with out having any flex joints and having welds crack. i run polys on my car no problems and my original down pipe (huron speed) was only about an 1" away from my mount, id say itd take some pretty serious heat to melt them.

If you're scared of melting something, just bolt it in solid.

Not really a question of being scared. Its can i use a good set of $30 polys rather than a $150 set of solids & be ok.

I'm using poly mounts but I have flex section on the turbo setup as well
Downpipe is probably 2 inches from the mount
Haven't had any issues

If you melt the motor mounts you have serious issues lol

Never had a problem hear. Also use flex coupler on hotside before turbos
