Cobra Sport Review

Following on from the success of the original 4.2 V8 Audi R8, in 2009 Audi launched the 5.2 V10 variant. The introduction of this new engine brought the Supercar’s performance credentials more in line with its competitors at the time such as the Ferrari F430 and Porsche 911 Turbo S.

2013 saw the entire R8 range undergo an extensive facelift which involved some minor cosmetic enhancements and the introduction of the stunning S-Tronic Dual Clutch Gearbox.

In standard form, the R8's exhaust has a satisfactory tone, generated by its high-revving Lamborghini-derived 5.2 V10. That being said, the factory exhaust is very restrictive, making for a somewhat muted and disappointing final article. Not what you would expect from a car with such a thoroughbred engine.

Sheffield-based performance exhaust manufacturer, Cobra Sport, have developed a solution for this in the form of their recently launched Cat-Back exhaust system designed specifically for the first generation facelift V10 model. This new exhaust is precision TIG-welded from T304 stainless steel and is fitted with valves that integrate with the vehicle’s factory configurations. The valves open and close depending on the vehicle's drive mode, so it stays subdued at idle but unleashes the full fury of its thunderous V10 soundtrack when the vehicle is in sport mode.

On the static sound test, Cobra Sport's system is 10db louder than stock at 4,000rpm in sports mode but only 2dB louder with valves shut in standard mode. With zero motorway drone, the new exhaust makes for a significant improvement without ruining the excellent everyday drivability that the R8 is famed for. A noticeable improvement in power distribution higher up the rev range was experienced during testing, thanks to the free-flowing performance exhaust setup. The Cobra Sport setup offers a 13kg (43%) weight saving over standard further enhancing the vehicle dynamics.

Cobra Sport's system is designed to fit in conjunction with the R8's standard tailpipes, but optional Carbon Fibre tips in O/E style are available should that be to the owner's taste. These tips really finish off the rear end of the supercar, and look particularly superb on vehicle's fitted with Audi's optional Carbon Fibre Side Blade.

Amazing!Review by AG
I bought my V10 R8 in Easter 2019 and it's always been a dream car of mine. Whilst I loved almost everything about it, I was disappointed about the muted sound, especially as I have a Spyder.

After looking for various options, I was pleased to see that Cobra had developed one. The team there were all great. Extremely knowledgeable, helpful and clearly enthusiasts.

I opted for the carbon fibre tailpipes too.

I use my car as a daily so I didn't want it to be OTT when in standard mode, but really wanted to release the roar when in Sport. What I got was so much better than I expected!

I find that I am driving more in Sport mode and using the full rev range so I can really hear it scream! It definitely breathes easier at the higher revs and feels faster too.

I love it! (Posted on 01/04/2020)
