s4r exhaust

I'm thinking about a system for my s4r and am currently considering the dp kit with termi slip ons, open airbox conversion and upgraded eprom. The other option for me is the full system from ferracci with a pcIII and open airbox kit. Any opinions on which is better and why? The ferracci system with the airbox kit and pcIII is slightly more expensive but does away with the cat. But DucSea has the termi kit in stock and my bike is already there for its 6k. Anyone have a ferracci system? hows the quality and sound?

How about the DP kit with the Termi full system, airbox, ECU and....cams

It's the deal of the century at $2800. You buy cams (regularaly $1800) and get a full system for $1000

We sell a lot of these.

For sure that is the thing to do. Slipons are just stupid as the S4R is running 40mm headers and the only gain is noise if you keep the stock headers. This is just to small for a 996. I would go for a full system.

A S4R with slipons makes max 110hp and a St4S with slipons makes about 120hp. They both have identical engines. This is ofcours if the are set up properly. Add sps cams to that and it will have potential to give 125hp
