The Maxflo + sport cat package gives you all the performance of the Supersport Turboback exhaust system but with a much more civilized tone and volume level.

The Maxflo exhaust replaces the rear exhaust section with a freer flowing light weight cat-back exhaust.

It's all mandrel bent for the smoothest curves, and uses .067" thick wall tubing for the perfect balance between strength and weight savings.

This exhaust system reduces car weight by 18lbs compared to the factory system. It is constructed with T304L stainless steel, providing optimal corrosion resistance and durability.

This high-performance sport cat features a 200 cell HJS HD catalyst, crafted in Germany, making it the ultimate aftermarket choice for catalytic converters. Boosting exhaust flow and enhancing turbo spool, the advanced high flow cat is a smart, emissions legal upgrade. 


The Maxflo cat-back combined with the sport cat gives you a bit more volume than just the Maxflo cat-back by itself, but it will still retain the refined Porsche tone.
