I am in the process of ordering my Apex-i WS II exhaust for my TL.
I am also building a CAT-Delete-essentailly a test pipe to replace the CAT.

I am currently running a headers already.

Will this set up: Headers, Test Pipe, Exhaust generate too much heat that will melt my rear lip (Wings west, it hangs lower than the OEM)

i tried to search, but didn't see anything

Thanks,

 

not unless the tail pipe ends behind the lip where as its blowing how exhaust on it. If it fits normally you wont have a issue
