Audi A5 B9 Rear Bumper Diffuser Aesthetics


Recommended Posts

My Audi is Daytona grey and there were a couple of things that I didn't like with the overall look; for this topic it was the rear diffuser colour and asymmetric exhaust tailpipe.

Ideally I would have fitted a twin exhaust pipe to create the symmetry, but that's not possible without an AdBlue delete which I didn't want to do. So, I decided to have the rear diffuser painted gloss black and the tailpipes too, so to lessen the imbalance.

The diffuser was painted professionally at a local body shop.

I did the tail pipes myself by first leaving them overnight in a litre of Hydrochloric Acid 35% to remove the chrome plating, washed them with a detergent and brake cleaner, before spraying with a can of Simoniz Gloss Black Engine Enamel. 

Very pleased with the outcome.
