I'd been thinking about trying this out for ages and finally got around to it. I installed an AeroTurbine 2540 muffler on my car. I reverted back to stock from the DP back a couple of years ago when the wagon became a tow vehicle and more of a part-time track car.
I've always thought the stock exhaust was a little too quiet on track to hear with helmet on, and replaced the muffler only with this. It sounds awesome ! I got a chance to hear the car in a tunnel today and grinned from ear to ear. The icing on the cake was driving down the street in my neighborhood at like 3000 RPM and hearing a car alarm go off
It's not really that loud, but did really happen !
