Got the paint above the exhaust melting and generally unsightly. 

Whats the best way to prevent this

Bent the exhaust brackets down so you have a bigger air gap

Can't say I've seen exhaust gases melting paint before tbh , has the car been mapped with pops n bangs or does it have anti lag ? 

If so it's probably due to flames rather than gases , if not It must be running really rich to have a high enough petrol content to degrade the paintwork..

Think you can buy exhaust shields , normally made from carbon fiber or stainless steel 

i expect its kicking out alof of flames which is whats doing it

I'd say it was the lack of space between the exhaust and the bumper myself
