any one know if the pro diffuser will work on a aftermarket bumper? or is it just for the stocker? any info?

 

Im interested too. I thought only the stocker.

 

I am pretty sure it can be made to fit on anything, as long as it doesn't make the diffuser sit to low.

 

thats what I'm thinking. I think i will call chuck at rotary extreme

 

what's the answer?

 

It'll fit on quite a few rear bumpers, but you can't use those little side pieces that it comes w/ with some bumpers. As a result, you may need to fabricate a very small bracket to attach it to the edge/underside of the bumper. I have it on my C-West rear bumper, but you can hardly tell since it's hard to catch details in black...

 

^can you post any pics, i would be interested as i have a c-west rear bumper as well.
