DEVELOPMENT AND TESTING: By creating a unique application for the 981 platform, we’ve focused on sizing the runners (2”) and collectors correctly to extract maximum power from the 3.4L engine while producing great gains from the 2.7L as well. We chose HJS HD 200 cell catalytic converters of an appropriate size to encourage maximum power gains. Don’t settle for smaller, cheaper catalysts when power and durability is concerned.
CONSTRUCTION: Each header is assembled out of T304L stainless steel and rigorously quality checked in-house. Proven design elements including port matched flanges, smooth radius primary tubing, and collectors that optimize the exhaust flow all work in conjunction to maximize power gains.
HJS HD 200 CELL 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 set is tested in a fixture to ensure perfect fitment then foam packed to ensure they arrive 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 for life! Our team will quickly work with you to resolve any issues or answer any questions that you may have. We cover our HJS catalytic converters with an unprecedented 3 year warranty while the headers themselves are backed by our Lifetime Warranty.

I got the headers installed yesterday at an Indy Porsche shop at Rd Atlanta. I took some heat shielding for the coil packs and they added that. The whole thing took about 4hrs and $425.00. I still have the standard exhaust and I’ve considered a cat-back system, but I don’t want it to be droning away when I’m on the highway. At startup, it is a little louder but not too much. What I did notice is it revs a little more freely at idle than with the stock headers. In that aspect, the sound is definitely noticeable. Out on the road, I think it accelerates a little better and in Sport or Sport + mode, it is a little bit louder. I think in low gears just driving slowly as if in traffic, there is a little more burble or maybe it is just a difference in the tone. You get a little more sound and a little performance improvement which does not come cheap on these engines.
I took the car out this afternoon for a little ride since it was raining yesterday. At idle, if I rev it up to above 3500, it definitely has a more menacing sound. As I said earlier, it also just revs more freely. I think there is a little more linear power down low than before too. It is not a kick in the pants like lots of torque, but definitely a little more power.
Jeff Hallam –
The headers sound great! Especially in “sport” mode with the PSE open! The KC Region has a DE event at Heartland Park in Topeka KS Sept 7-9. Can’t wait to see the torque improvement on the track. Thanks Again

I put Soul catted headers on a few weeks back, and am using the supplied Cobb tune. My car does not have a sport exhaust.
My take: a nice increase in power and torque above 4500 RPM. The car really, really comes alive; it feels every bit as quick as our 991 C2S now! It is probably making about 370hp and the power to weight should be identical on these 2 cars (C2S is PDK).
The exhaust note is louder by about 10% when cruising and 25-30% at WOT. It needs more sound still. It sounds a little quieter than the C2S with Fister mufflers, for comparison’s sake.
