GReddy RS Race Cat-Back Exhaust for Evo 7/8/9 (10138403) *Backorder ETA 1/27* MANLEYPISTONSBRZ We have always used theThe GReddy RS Race cat back exhaust for Evo 7 8 9 features a straight through, non resonated design for maximum flow! Made using full 3" stainless steel and a polished muffler with a single 115mm tip. GReddy has not released the official weight, but the Revolution version weighs 25. 3 pounds vs OEM at 34. 7, and this RS Race version does not have that extra resonator that the Revolution does, so you'll save a little over 10 pounds with this exhaust.
