I thought the conventional wisdom was that you couldn't get any gains from a new axleback on the Sixer...only a better sound. John, you and Lidio have proven the experts wrong once again!
But...dang it...now I've got one MORE thing on my "short list" to buy...
Thanks much for the info...
zregime said:...So I just went to the MRT website and the only thing I'm seeing is the Aero Turbine, which appears to be for the GT only? Is that what you got on yours?
rgensemer said:John, man that really sounds good! The power gains are unreal for a muffler and your dyno results contradict everything I've read on these forums because you are proving a 15 RWHP gain over a stock setup! Unreal, but the dyno doesn't lie. Imagine the sound and gain if you go to duals.
