With my Wildcat and now the Maverick soon I see all these fairly pricey aftermarket exhaust systems making all these wild claims, and NO ONE is backing it up with hard data. I just don't understand why they won't offer proof of the performance. You ask them for it you get ignored or shady responses. Why won't someone stand up and say HERE IS OUR DATA AND PROOF. Do a Dyno before and after, it's that simple. That would get my business in a heartbeat. Till then, I am not taking a 800-1200 dollar risk. Am I alone?
