Two Brothers Comp-S 2-into-1 Slashcut Exhaust System

So long as you don't plan on adding more than an air cleaner in the future, the Dynojet Power Vision 3 Fuel Controller is the way to go. It's easy to install and reconfigure for baseline updates like this exhaust and various air cleaners. If you plan on going beyond that, eg. big bore kit, cams &etc., that unit doesn't have the range of tunability needed to deliver enough fuel for those changes. In that case, we recommend a Dynojet Power Vision along with a trip to a competent tuner to get the most out of a setup like that. The latter device is built for major modifications and, basically, has no restrictions in terms of tuning adaptability.
