This is the RDLogics RDLogics Revo 2.5 and 3.3 Top-End Polished Aluminum Exhaust Pipe Set.  This gives more top-end RPM performance to the 2.5 and 3.3 engines, as well as increased power throughout the entire power band.  These look awesome, and they perform very well.  The performance and sound from the RDLogics exhaust system is great!  This is a direct fit in place of the stock pipe.

RDLogics parts are built with the racer in mind, and they are constructed of the highest quality materials. These are a must for high-performance vehicles and people who want the best.
