    Let me know if you want me to measure any additional spots.

    This photo ought to do wonders for aftermarket exhaust sales. Good lord, what a mess. Did the same folks design the intercooler plumbing as well?

    is it 1.8" right before the Y also? does it go from 1.8->2 sections of 1.8?

    I remember stopping by a Porsche shop well known for its 911 headers, and the (very good) welder there making fun of the then-new 2.5-liter Boxster's headers, with its bizarre oval "wine-glass" inlets that exited into awfully small, crude-looking header pipes. When the shop guys were done laughing at Porsche's pitiful, cost-cutting engineering—and done building a beautiful set of stainless headers with gorgeous collectors—they went to a dyno. The car made less horsepower and torque than it did with the ugly stock stuff. I'm still curious about those tulip-like/wine-glass inlets.

    The takeaway for me that day was that OEMs know a lot more than independent speed shops, and can spend far more on testing and development of engines and systems. Usually, the only ways the aftermarket can beat the factory is by foregoing customer taste, marketing decisions, cost constraints, or emissions controls. Even then, they often fail to eclipse the factory setup, despite all the hype and moar noise. But it sounds louder. Every now and then, the best aftermarket companies beat the factory, but it is rare in my experience. It seems like this might be one of those cases.

    In the case of the exhaust photochop above (thanks for this SuperTony...very cool!), I have to wonder if the diameter variations have to do with the many system variations and experimentations mentioned by the SRT folks on their way to getting the Abarth to perform and sound like it does. And the stocker sure sounds great. There are many areas of the Abarth I'd like to improve. The exhaust isn't one of them—but I stand ready to be amazed by someone's system if the opportunity to really listen to it in multiple situations arises.

    You have to listen to the sound of a Super Sprint exhaust if you haven't. If I had the $ it is a change I would make but otherwise I agree that the stock sound needs not be tampered with.

    Checkout a video from Edwin (Gigante), riding behind him it sounds like a low flying aircraft is about to land on your hood.


    When under load it sounds a lot nicer!
