I have factory Stage 1 pipes. They are very loud. When I first had them, I thought it was too much but I have grown to like them and wouldn’t swap back now. Yes, they are Aero Racing ones. I was told by my dealer that the factory takes the view that if you fit anybody else’s Stage 1 pipes it will invalidate the warranty. In light of that (whether the factory is right or not, I didn’t want to have an argument with them over invalidation of the warranty), I went for the factory/AR ones when I would probably have chosen the G56 ones otherwise. Be aware the factory ones are prone to failures. My first set had to be replaced (under warranty) within a month and on this year’s Grindelwald trip another car had its new(ish) Stage 1 pipes fail. I
What is the failure scenario with the Stage 1 factory (A/R) pipes? Just so I know where to keep an eye on mine... I had previously only heard of cracking issues with the stock pipes, and thought the larger diameter stage 1 pipes may be stronger.
