The Porsche 718 Cayman | Boxster series can benefit tremendously from a performance exhaust system.  Why is that?  Because these vehicles featuring the 2.0L or 2.5L are now turbocharged!  This is huge for the Porsche performance world as exhaust flow truly makes a difference.  Unlike the previous 981 naturally aspirated engines, the 718 turbo needs no restriction after the turbo.  However, it is important for street cars to have a fine balance of exhaust flow and sound.  With this exhaust, your 718 now has a beautiful exhaust tone that is tolerable when cruising, but mean when heavy on the throttle.  This is exactly what Agency Power has delivered with the new Performance Exhaust for the Porsche 718.  The exhaust features all T304 stainless steel with precision TIG welding.  The exhaust have an eloquent satin finish and are a direct replacement for the OEM system.  The exhaust saves you huge amounts of weight off the rear end.  The stock system weighs nearly 50lbs where the new Agency Power exhaust is only 25lbs complete.  The exhaust features 2.5 inch diameter piping with dual race inspired 4 inch exhaust tips.  With the additional performance as the premier benefit, the exhaust sound is a must have modification for any Porsche Boxster | Cayman owner.
