Why We Choose HJS Catalytic Converters:
HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.
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. Speaking of which, it saves 18 lbs from the car vs the factory system. We also use T304L stainless steel for all the exhaust tubing. This gives the system ultimate corrosion resistance and durability. The sport cat is built with a German made 200 cell HJS HD catalyst, which is the top of the line aftermarket solution for catalytic converters. The high flow cat further improves exhaust flow, and helps the turbo spool up faster.
SOUND: the Maxflo Catback combined with the Sport Cat gives you a bit more volume than just the Maxflo Catback by itself, but it will still retain the refined Porsche tone. This system is very livable with no droning, and the activation of Sport mode greatly increases the sportiness and growl of the Turbo 4 engine. You'll also notice a slight increase in turbo spool sounds.
