Thanks. Yeah they are too expensive for sure, but after reading that other thread where people said they found themselves going back to the oem exhaust because some aftermarket ones are too loud and they get fed up with that, maybe this one is the way to go if money is not an object. (which is not my case unfortunately )They are excellent systems, we've used them in the BMW community for the E46 and E9X M3. Unfortunately they are quite pricey and I don't find it justified but if you are looking for a top notch and sound controlled exhaust, this is the way to go. The ability to transform the car from subtle to downright aggressive is unmatched.
