2nd Gen Rear exhaust burned bumper

[jjm916s]

Hello, I have a 2nd Gen. Love the fact that the exhaust comes out the back. Always wanted one. However, Its burned the opening around it and its warped the plastic around it a bit. Its not extremely noticeable, but it does keep me up at night knowing its there. Any suggestions on an aftermarket rear diffuser that can hide the burn around the rear cut out but also serve a purpose?? Thanks for your time and consideration.

Autoform rear diffuser.

Do you know what exhaust system you have?

I have a 4 Blade rear diffuser fitted to my car using a Belanger system my pipes do touch the top of the rear diffuser and the diffuser does have some scorch marks on it, but being black it does not matter.

I have also fitted 2 other 4 blade rear diffusers on my friends vipers but they were running the Corsa system. Now the rear cans on the corsa are a much bigger diameter than the belanger system so the 4 blade diffuser has to be modified

Heres what I mean.
Here is a pic of my diffuser with the rear belanger pipes.

Here is the corsa set up

As you can see, I had to cut a secondary hole in the diffuser to allow it to fit better due the the larger cans

If you don't want a rear diffuser you could always get cut a stainless steel plate surround or carbon around the outside of the hole. :)

Nice Job!

The Autoform aftermarket suits the large or small diffuser selection. If you want something in-between there are other options. Autoform is good quality if you go that route. I have many of their pieces.

Thanks so much. The Pictures are a great help.

Also, look at your tune. The rear bumper burn is not unheard of, but is somewhat uncommon.

+1 my exhaust was extremely hot while my car ran rich.

i ran no cats on a boosted silver car with 50K miles and never burned the bumper. sounds like you got issues with your tune for sure
