Exhaust (metal/chrome) material for a SBR mod

I am currently making a slammed/static SBR4 mod and have made a custom exhaust for it.

The problem is that the car does not have a metal/chrome texture linked to the car and the exhaust looks weird because of it.

As a joke, I used the mirror texture on the exhaust but it is way too shiny to use in general.
Would someone be able to help me make a metallic/chrome exhaust texture for the mod?

This is what the mod currently looks like


Any info on how to create a material for this would be great.

 

Look for generic_perf_parts, it's a shared material used for, well, generic performance parts. It has some segments suitable for exhausts.
