    Re: V10 vs GT exhaust

    Thanks for clarification. That means the engine note will be dramatically different. But it's still hard to comprehend the exhaust note being very different between the 2. It means that one can modify the things you listed, without touching the exhaust system, to achieve a better exhaust note?

    Part no for the rear silence with secondary cats is: 420251051J

    Engine tuning is different. The air intake system is different, air fuel mixtures will be different, timing will be different, throttle map is going to be different....all of these will have an influence on exhaust tone.

    Sure thing! I will look into it for you and send my findings your way.

    Re: V10 vs GT exhaust

    The R8 V10 and R8 GT systems are not interchangeable, and here is why.

    First I looked into the engine codes and part numbers, which are different-
    R8 GT Engine code is- CMPA – Exhaust P/N - 420 251 051 JX
    R8 V10 Engine code- BUJ – Exhaust P/N - 420 251 051 HX

    I then did a bit more digging to define an exact difference. The pictures attached sum up one key difference- the tips. We all know that the bumper of the R8 GT has a different sized cutout than the current R8 V10. Vuvision even mentioned that he needed to order a GT specific system on page 1 of this thread.

    As a side note, the 2014 R8 appears to have this same cutout in it's slightly redesigned rear bumper cover, so there is a chance that 2014 R8 V10s and the current GT will have an interchangeable system. Obviously this is speculation though until I can physically lay eyes on the car.
