If you only run a mild AL map and don't use it to often it will be fine. The exhaust does run hot in a short space of time, 5 mins and it's very hot but soon cools once you have switched it off. I made my own exhaust system and it seems to be holding up ok. There is some baffle rattle that was not there before the AL was fitted so I may just nip the back box in a vise to fix that. I'm sure it will be fine on your car......it never does enough miles to damage anything
bit like mine really.
