I had no issue with the Y-pipes and the Berks matched right up on my 2010 370 sport. Good luck Friday.

The change I've noticed with the HFC are a nice raspy sound in the mid to upper RPM when you half get into the throttle. If you are real gentle with take off, you hardly notice. I guess my thought is it's just right.
The performance is a bit better (there are stats somewhere to verify the fact). The trade-off in my situation is a loss of about 1 or 2 MPG.
