MAXFLO Exhaust System

This MAXFLO Exhaust System is brought to you by FabSpeed for your Porsche. All 987 Boxster/ Cayman/ S Products 2005+

UP to +19.4HP DYNO tested power improvement as measured at the REAR wheels with the Fabspeed STAGE 3 kit. That is +25HP as measured at the CRANK/ENGINE FLYWHEEL. A DME chip reflash $1495 would add another +15HP so you will be up over +40HP verusus stock.

High quality T304 stainless steel mufflers and C.N.C. mandrel bent tubing for maximum exhaust flow and power. Mirror show car polished finish. Saves 10 lbs from rear of car.

Eliminates 2nd set of unnecessary catalytic converters. Each and every new 987 Boxster and Cayman comes with 4 cats. The 2nd set is eliminated for reduced backpressure and better exhaust flow and much improved sportscar sound.

Noticeably better throttle response

No Check Engine Light Guaranteed as the1st set of main cats are the only ones needed to pass emissions and these cats are located on the headers. Removing the 2nd set of cats is mandatory on any quality aftermarket system.

No resonance - Pure pleasure
