Thanks for the info Russ...

I did purchase it earlier this morning after reading some more info on it on the net. Like you said I am hoping it enhances my Calmini exhaust systems sound and most importantly performance. Would love to have a little extra for passing in the mountains on my way to trail runs. Only time will tell but from the posts I have been reading people have been getting great results with the FIPK and Calmini combo.
