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.

Have not turned on the radio since the header, muffler install. Deep throaty exhaust note at idle with a newly noticeable turbo spool sound at acceleration. Surviving Los Angeles freeways just got fun, car runs much cooler in bumper to bumper traffic with turbo lag almost non-existent. Obviously, these early 930's were detuned coming into the US Market and the factory exhaust is a clear indication. Overall, night and day performance difference, performance comes across all power bands and gears. Great investment, worth the spend.
What a beautiful system for a 930 Turbo. Thank you Porsche for making a replacement system NLA! Thus I was forced to look elsewhere. After much homework I went for the Fabspeed and I was not disappointed. Lovely to look at,solid,beautifully made,and it fitted like a glove. Sadly, all discreetly hidden under the rear valence. When used quietly there is a gentle burble. When angry the car howls as a 911 should. Performance and responsiveness appears significantly improved and the classic turbo lag has almost disappeared. I love it.
