Audi a4 b7 rear splitter question

[Youngy]

Iv got a tdi 140 with just the twin pipe ine side but im putting on an exhaust with double pipes (one either side) so i need a rear diffuser with a cut out both sides but cant find one so can i take just the bottom part of the bumper from another model ie b6,b8

Thanks

Yea, you'd be able to take the lower bumper off and attached it to your a4 🙂

Cheers

What off of a b6 or b8 if so which one 

[Steve Q]

It'll need to be the same model as yours 🙂
