Kenne Bell Noise Revisited

Well since my last post about noise following the install, I now can say that while there is still an on/off chirp/squeal (similar to a belt slipping) at idle up to about 1000 rpm it is running a lot quieter after 450 miles of use .
Kenne Bell never did respond to my emails but I was able to get through quite easily on their support line .

It is truly a different performing car .

An added bonus is the fact that mileage is essentially unchanged on longer trips.
