The GT4 Gets An Over Axle Pipe Exhaust From Soul Performance Exhaust

It's time to start digging into exhausts for the GT4. Soul Performance is one of the first to market with a legit exhaust solution, so I'm going to try out all of them in typical OG fashion! The Soul Performance competition over axle pipes are a great upgrade that are amazingly easy to install (unless you break a stud) and gives the GT4 a more aggressive tone.

[@joetacchino4470]

Damn, that sounds good. I wasn’t really a fan of how “grunty” the stock engine is. But opening it up sounds REALLY good. You can definitely hear it’s not as high pitched as the 981 (which is just a 991.1 Carrera S engine) nor of the GT3’s 4.0 liter. I think it sounds a lot like an air cooled race car. Wicked.

[@ObsessedGarage]

It's still a little hollow sounding. I made an in-car video today that will be up tomorrow. I also disconnected the valves.

[@ericlim7994]

@@ObsessedGarage From what I've heard, I prefer aftermarket 718 GT4 to aftermarket 981 GT4 but agree that the 981 has it over the 718 if you compare stock to stock. The 981 is overall too raspy sounding for my tastes, and I also dislike pops and crackles.

[@Firehawk968]

The US has filters it’s just unmonitored so no ECU adjustments needed when removed

[@pauldb5]

Very good video as usual. Don't you have to do an ECU tune since you deleted the OPFs ?

[@ObsessedGarage]

Not on this car. As per other comments, we don't have a sensor for the OPF in US, so no CEL for removal.

[@cnibbana]

Why didn’t you do a before and after on the exhaust sound? Also, did you answer whether the US spec OPF filters are hollow or actual filters?

Getting ready to order the OAPs for my Spyder, and am wondering if things will go a lot smoother if I pre-soak the studs with penetrating oil. That seemed like the only PITA part.

[@Goflyingbear]

Well shit, I'm doing the same install. Passenger side removal and install was fine. Driver side one of upper studs got jammed while backing out. Letting it soak in PB blaster right now, but I think I might have to cut the stud like you did, or pull the rear bumper and exhaust off. :(

[@philtechGT3]

Hi Matt. I'm a 718 Cayman GT4 owner (also Gentian blue), I installed the Akrapovic Slip-On Race Line (rear silencer) and the Link-Pipe set (= over-axle pipes) and the sound was CRAZY ! I had to put the stock over-axle pipes back because of sound regulation at Spa Francorchamps. But you definitely should consider this exhaust made of titanium. And as you are even more meticulous than me, the astonishing build quality of Akrapovic will make you happy !

[@BillLee3]

Hi, Matt. Just got a GTS 4.0. I'm currently doing the Soul valve controller and considering doing the resonated Soul OAP. This is sort of a daily driver (also have company car), but that just means I don't want too much drone, that I gotta keep it somewhat quiet in the neighboorhood and I want to be able to close the valve and listen to the stereo when just cruising on the freeway. OTOH, during much of my driving Id like to open up the PSE and hear her sing. Is doing OAP only viable for that?

[@ObsessedGarage]

I would definitely do nonres. Your valve controller will give you full control.

[@brendanzhang6330]

Matt, the US market cars have exactly the same filter as EU cars, the only difference is that in the US the filters are unmonitored. I.e no CEL

[@bmahoney1568]

You should have wrapped the pipe with thermal insulation. The cayman engine bays get very hot and the motors heat soak. Secondly, the heat coming off the down pipe can heat up the brakes/brake lines, which also can be an issue draining on track.

[@ObsessedGarage]

I get that, but we should be fine on the street.

[@jmartprjmartpr9944]

@@ObsessedGarage Since you took out that stupid gas filter the system wont heat up as much. Never had a problem like that on my 981 GT4 on the track with a full GT3 exhaust conversion doubt the 718 will be any different once you do the mid pipe swap.

That thing is going to be nasty with a full exhaust. Night and day it makes taking out those filters though.

Surprising that they put the filters in without use because there's a good amount of expensive materials in them. They usually scrap for over £100 so can Imagen manufacturing isn't cheap

The American cars come with the filter as the euro cars but the American cars do not have the sensor attached to it as its not required, that’s the difference.

[@joshgorman4521]

"This should come right out"... Famous last words Also on an unrelated note is the GT4 ironically the new GT3? If you think about it the price is about where GT3's of old sat, the newer ones have huge price tags along with huge amounts of depreciation. To me the GT3 was an aspirational sports car, but it was attainable for the "common" person who worked really hard. Now it's become a stretch for those folks, it's almost into supercar territory.

[@jeebus2121]

Is the depreciation only with the 991.1? I could understand that depreciation for lack of transmission options, the few that caught on fire, and the successor having more power, a new engine, and a manual.
