it looks good so far until this


there u can see how it doesnt fit clean. I think i might take some body work to fit..

 

BRR made it fit perfectly...and he clearly stated it doesnt take any body work at all.

 

must just take some brainstorming

 

oh my bad....

 

so Andpto,are u putting it on?

 

anyone know if the magnaflow exhaust will fit the RT or SRT rear bumper, and if it will look right?

 

dont know anything about the srt-4 bumper, but as far as the R/T, i think it was that only the rt exhaust(of course) and the Thermal would fit it
