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. If you'd like to learn more, watch our video about HJS catalytic converters.

I should have done this 15 years ago when I bought my Boxster S. It was easy to install and the sound is better than I had imagined. Combined with sport/race headers, I can tell a difference in acceleration for sure. With the top down it really does sound amazing. At highway speeds, there is little to no drown. At lower speeds when RPM's are 2000-2800 there is some drown. But I don't usually stay at that RMP for long :) Side note, the mufflers are polished and really nice looking. There are laser engraved logo's on the pipes too. Worth the money.
I could not be more pleased with the 986 Maxflo exhaust system. Installation was a snap, and the sound is wonderful. The sound is very tolerable at highway cruising speeds, and it comes alive when the pedal goes down. The sound is so smooth with just a little burble on downshift. I have cat free headers and the Maxflo for 2000-2004 Boxster without cats. I feel this setup would greatly benefit from the Fabspeed tune and intake system. I will do all of this in time.
smooth exhaust note that opens with a deep bellow and ends in a creamy shout. not too loud, definitely not too quiet- this volume was exactly what I wanted. shipping took a bit long (understandable), but customer service was great (someone answered my questions every time I called in for an update). only downside is that the tips stick out a bit too much for my taste, but it's a minor thing and you'll forget about it once you hear that flat 6 under load. great quality welds and engraving, overall high-level product. can't wait until I get bored of this volume, I'll be back for headers!
