Porsche arrived a little late to the current roadster party, but the wait was well worth it. The upgraded Boxster S for 2000-04, with nice power and mid-engine platform, is a great handling sports car. BORLA RD engineers developed a completely new mandrel-bent high quality austenitic stainless steel package with emphasis on weight, as the exhaust is positioned significantly back at the very rear of this vehicle. The new BORLA Cat-Back™ system (PN 140115) managed to come in at less than half the weight of stock, adding to a better balance for those winding highways these cars love. PN140115 flows an impressive 263cfm more air than stock, which accounts for the added performance. A true testimony to the incredible effort of a professional staff, taking a great car and making it even better. BORLA always is a value-added component, and that was never truer than in this application. The revolutionary BORLA Cat-Back™ looks great with the Siamese 3.5” oval, angle-cut polished tips. The incorporation of a throaty powerful sound, solid power enhancements and better gas mileage make this BORLA exhaust a winner for this exciting race-bred Porsche Roadster. While many exhaust companies talk about racing, BORLA mufflers and headers are tested every weekend on race tracks around the world. The BORLA success is unmatched, and that effort transfers to the BORLA street systems that are a perfect match for the similar Porsche legacy. BORLA backs these and every Cat-Back™ system with an unequaled written Million-Mile warranty.
