I had one of these put on my V10 5.2 by Vinnie's Exotics and it was the best aftermarket money I've ever spent. The sound is awesome, the weight reduction is real, and the reduction in heat soak is incredible. After a long run, I'd pull my car into my garage with the stock system and it was like a furnace. Now, there is no discernable heat given off. Everyone who has heard it loves it. And btw, i have no affiliation with GMG. For V10 owners I would highly recommend it. Then after that, get the APR flash, another awesome mod.

 

i also have the gmg exhaust on my v10. truely awesome! gmg please make more great products for my r8!

 

Thanks for the kind words guys looking at many of the systems on the market I see that our system is one of the most powerful bolt on system on the market and also the lightest one as well.
