DEVELOPMENT AND TESTING: We wanted to build an aggressive catted system that offers a modest increase in tone – including pops and burbles on deceleration – without triggering a check engine light. Support for high power was another consideration – necessitating 3″ tubing. We experimented with adding a mixing chamber into our X-pipe design. Analysis in 3D CAD software showed a general increase in velocity gained downstream of the mixing chamber across a band of measured pressure and temperature levels. This produces optimal flow characteristics, reduced backpressure for higher HP, and enhances the sound quality of the system. Quad race resonators make a discernible difference in reducing drone while encouraging a more refined exhaust note.
SOUND: The HJS catalytic converters flow extremely well, letting through more turbo and flat-six sound through. Quad resonators add a refined tone and cut down on droning in the cabin. The level of volume is perfect the owner looking for a sophisticated increase in sound – aggressive on heavy throttle inputs while offering a mild and sporty presence during cruising.
CONSTRUCTION: Each Sport X-Pipe Exhaust System is made from mandrel bent T304L 3″ .065″ wall stainless steel tubing, straight through race resonators with a full metal packing design for maximum durability, and laser cut brackets for perfect fitment. Custom Mikalor Supra Heavy-Duty Clamps are included to securely install system to vehicle.
HJS CATALYSTS: The highest quality catalytic converters available, known for their industry leading flow and durability. They are efficient enough to meet strict EURO 4 emission standards while still allowing for an increase in flow – all without a check engine light. The HD design uses premium triple foil winding for maximum strength. The brazing stripe is an extra feature in the interest of durability – it prevents the core from moving or experiencing any damage from sustained high horsepower abuse. We use a large and appropriately sized catalyst to allow for maximum gains – no compromises here!
BOLT ON AND GO: Each exhaust is tested in a fixture to guarantee fitment and then foam packed to ensure it arrives in perfect condition. Thorough installation instructions are included in the box for a straightforward install that can be performed by most DIY enthusiasts.
LIFETIME WARRANTY: Enjoy your SOUL exhaust components with confidence on both the street and track as they are covered by our Lifetime Warranty! We cover our HJS catalytic converters with an unprecedented 3 year warranty while all other components are backed for life! Our team will quickly work with you to resolve any issues or answer any questions that you may have.

As a real Customer, I speak from experience with my thoughts on this business. The guys did a catted X-Pipe for my 996 Turbo. During the process, Mike was more communicative and enthusiastic about the product than anybody I’ve experienced. I received progress reports, pictures, and musings from the shop every day (like the Huracan system they were doing at the same time as mine).
As they worked to install the final system, their attention to detail was evidenced by the fact that they ordered aluminum clamps to replace my rusty OEM units and added components to ensure 100% symmetry.
Then I picked it up. And I experienced it. And my car guy friends experienced it. And we all compared to other 996 Turbo options. And we all agreed this system is among the best we’ve heard, including the majorly excessive titanium and unobtainium options. I could go on, but it’s obvious that I’m abundantly satisfied.
The car sounds insane, the quality is fabulous, the sales/support/aftersales is flawless. Simply put, these guys are incapable of being anything less than the newer, shinier, hungrier disrupters in a complacent industry. The other guys have noticed and for good reason. Soul is the real deal. Any car I own that is exhaust-worthy will have a Soul unit if available – in fact, I’m trying to convince them to develop a system for my G500… box dice yet. 🙂

I’ve been looking for an exhaust for awhile now. I wanted an X pipe design, preferably 3″, that had 200 cell HJS cats and that I could reuse my stock “sport” tips on. In looking around Soul Performance had all my boxes checked. A quick call to John and they were making one for me and had it winging its way over to me the following week.
First impressions, SP (Soul Performance) does a fabulous job packing these! Foam wrapped, comes with nice, detailed instructions with pictures, exhaust nuts/washers, stickers and a micro fiber towel to wipe the exhaust down with as the exhaust has a satin finish and any fingerprints left on it will burn in.
Install impressions! This system went together really smoothly. I didn’t have to modify anything, oval out any holes, play around with positioning, none of that. Even the tips lined up pretty much right away. Super impressed by it, as well as the fact that SP basically provides everything.
Well, I think it’s freaking awesome! When you’re on it, it’s rowdy, raucous and rips! There’s a huge power gain, the turbos spool noticeably faster and my traction control was going crazy in the first several gears when it never did before with the stock exhaust. The exhaust in the cabin is noticeable. I’ve got about 100 miles on it now and its burning in and mellowing out some. I expect that to continue. That said, you can carry on a conversation at normal levels, I don’t have to raise my voice at all. You can hear the radio just fine, don’t need to crank it.
The exhaust doesn’t drone but at around 2200 rpm the tone of it is louder. Cruising at closer to 3000 rpm it’s noticeably more quiet in the cabin. Windows down this thing rocks and rolls! On the throttle its a giggle fest, I don’t really get great gas mileage on this thing as it is, I’m sure I’ll be dipping into single digits now for sure!
Conclusion: This exhaust is well made, well packaged and goes onto the car with no hitches. Performance gain is palpable, sound outside the car is amazing. Inside the car the sound level is quite livable, I wouldn’t have a problem road tripping this car to California. With the HJS cats its 100% smog legal, no check engine lights, no stinky exhaust smell. All in all, I’m quite pleased with my purchase and recommend Soul Performance!
