The high-flow cones ensure the best possible exhaust flow into and through the catalyst and the best possible performance. HJS tuning German catalysts guarantee that the emissions limits stipulated for emissions tests are complied with and they can also be used in vehicles kitted out with EOBD.
HJS Product Training. Meet the strictest of emissions standards while freeing up power with an HJS cell catalyst downpipe. This downpipe is produced by HJS themselves as a solution to meet the strict requirements of Euro Which is exactly what I was hoping for. Most importantly, my butt dyno is telling me that the downpipe added some power.
The car feels to pull through the gears much easier. Enough so for me to actually notice a difference. Overall, I think this was worth the money and made the car more fun to drive — without costing an arm and a leg. Matt Chow — February 13, Fit and finish of the downpipes is great, the o2 sensor installed with no problems.
Removal of the stock setup required some wrestling of clamps and stubborn screws, but everything was installed and buttoned up within 2. Lukejt Rennlist — November 29, Sounds really nice in sport mode. Definitely a slight bump in seat of the pants performance all around.
I will get some video soon and share it for everyone to hear. More crackles with he Soul downpipe, and even sometimes when not in sport mode. Also super stealthy when you want to be. I recently installed a Soul Performance downpipe on my Cayman S a few months ago. I wanted to get a few miles on it before giving my impressions and now unfortunately have to put it to bed for the northeast winter.
I also want to start by saying I have owned Cayman S, I should also state my car came with PSE so not sure how that effects others outcomes. Sound: Definitely a change in noise, the note and engine just sounds more heightened and engaging, more definition in the different sounds. I think this helps reveal the characteristics of this engine more and help stand on its own in the world of Porsche boxer 6s. I originally was having issues with the sound but the downpipe greatly helped me develop that relationship with what was a great performing car.
The personality has been discovered in this great engine for sure. Although the volume may have gone up slightly thats not what this was about but the new sounds will peak the senses. It also incorporates their free flowing, straight through design, along with proprietary hi-flow cell "race" catalytic converters will improve the sound and performance.
The cell catalytic converters offers a quicker turbo spool possible, along with increased torque and horsepower.
The design is constructed of high quality T stainless steel and the muffler is packed with stainless steel wool for years of trouble free performance, even under extreme use conditions.
