When you’re converting your B8 Audi A4 to Quad Exhaust, you kinda need to do something about the rear bumper if you want it to look right – and if you want it to look really good, you need a diffuser to frame that work of art exhaust system you’ve got ordered. That’s what we’re up to on this B8 Audi A4 2.0T, and we’ll be giving you a look at these sleek B8 Audi A4 Exterior Mods that really dress up virtually any B8 – and Mod Expert Blake was the guy to help make this install happen.

We’ve started by installing DEVAL Carbon Fiber Rear Diffuser for B8 Audi A4, which gives us a great base to work from. The carbon fiber gives it an aggressive look and the pronounced fins drive the performance look home, and the wide dual openings on either side will give us the clearance we need for the AWE Tuning exhaust we’re installing.

We’re installing a Touring Edition Cat-Back Exhaust for B8 Audi A4 2.0T from AWE Tuning to change both the look and sound of the car – the resonator in the Touring Edition exhaust also translates to a more refined exhaust note suited to street driving.

As we installed the exhaust, we couldn’t help but notice the BC Racing Coilovers for B8 Audi A4 that give the car its stance and the Hankook Ventus V12 Evo2 Tires are obvious with their distinctive tread.

The tips of the AWE Tuning Touring Exhaust for B8 Audi A4 are individually mounted to allow you to adjust them for the perfect fit.

Up front, a Carbon Fiber V-Style Lip for B8 Audi A4 has already been fitted to compliment the wheels.

The addition of the DEVAL diffuser and the AWE Quad Exhaust for B8 Audi A4 has completely transformed the rear end of the car, giving it a super aggressive DTM-racer-esque kind of look.

Here’s how the tips look in the diffuser out in the sunlight. We love how the sun catches in the weave of the carbon fiber.

From the side, the contour of the fins in the DEVAL carbon fiber diffuser stand out and gives the car a more aggressive look than many of the other options we’ve seen available for the B8 platform.

At the rear 3/4 view, with the car on a set of aftermarket wheels for B8 Audi A4 and sitting low on BC Coilovers, the overall look of the car is both classy and aggressive, and unlike every other A4 parked at Fashion Island.

The Carbon Fiber Front Splitter helps a lot too, however we think an RS style grille would really be the finishing touch on the exterior of this A4, but it looks great either way. Give it a look for yourself in the following photos.
