Anybody have any info on aftermarket exhaust for the Apex, pros and cons? Iam leaning towards the Excell for the cool sound and wieght reduction.

I will have an Excell system on an Attak on the dyno next week and will let you know the results. I will also have some air box modifications to test as well.
