    My local track (GoPro Motorplex) has a KT-100 Senior class that utilizes the 4 hole can (RLV 7548). I know that WKA had implemented the pipe (7448) as a noise mitigator with the claim that performance was “same”. I’d like to persuade GoPro Motorplex to allow the can or pipe, but am looking for corroborating data as to performance equality. What is the current consensus on can/pipe mix? Thanks in advance,

    NEvermind. I found the cached page on the classicEKN that explained pipe as 1 sec faster per 25 sec laps. Looks to be no comparison. Guess I’ll be buying a soup can. Drat. I prefer pipes. Oh well….now some else searching will know, I guess.

    The Pipe is better sounding, better performing and a ton more fun. Talk Eric in to making the change, absolutely no one will regret it. For Senior guys at 345 or higher, the Pipe is absolutely a no-brainer.

    I don’t understand, you like pipes and they are faster but you’re buying a can?

    I like the can myself, less power = smooth ride, easy to mount and no hassle adjusting the chain. Engine tires clutch, everything last longer.

    Gif – when all they run is 1 KT-100 class, you run their rules, and their rules are a soup can at this point. I’ll discuss with the others in the class about the switch… :)

    We have approx 10 Yamaha Sr’s racing the pipe and it is far better than the can. There is a bunch of us from Georgia that would like to come up and race but we haven’t due to the can. Maybe you and others can get them to change for 2014.

    A bunch of us plan to race at Atlanta Motorsports Park on Dec 14th with the pipe. More info at http://www.tsracingatlanta.com.
