Porsche Over Axle Pipe Install and GPF Delete 981/718 Cayman and Boxter

[@cr4zym3x1c4n]

Not going to lie it’s so nice to see someone from cali doing Porsche videos, everyone’s from England 😂 If you’re in nor cal I’d love to see this car in person

[@JetFuelOnly]

I am in the East Bay, connect with me on IG if you have it!

[@AbdulKhan-fj5qb]

EVERYTHING we need is in one video! Awesome work. Thanks

[@rickgoracy5521]

Comment on heat. From one of the manufacturer of OAP. With the stock GPF pipe the filter causes higher temps based on the filter restriction. I’ve added the OAP and didn’t insulate them, wrong or right. I thought about doing the heat wrap fabric I’ve used on motorcycle exhaust. When I get bored I may give that a try. Great video !! 100% love the improved exhaust note.

[@JetFuelOnly]

Yeah those filters are big heat sinks. Maybe on a 55-65 degree day and oil temp stable you could check your temps after shutdown?

[@Zach-sq1gs]

Another great video! Very concise and I appreciate your editing choreography - very professional. Found this through your post on the 718 forums.

[@JetFuelOnly]

Thank you!

[@gmund317]

Best install video on KZbin. Thanks!

[@christophercatuogno6615]

Great video. Thanks for making. How about one showing how to install BMC air filters? A perfect compliment to the OAP’s.

[@JetFuelOnly]

For sure. I need to get those at some point and I’ll film it when I do

[@gilharir5025]

great job

[@mpp9964]

You should try stock muffler, resonated over axle pipes, 200 cell headers. I think that might be the sweet spot. Headers and resonator will reduce drone

[@porschestories409]

just ordered

[@Mario-lj7gm]

Great video, just like the oil change one. You make these DIY jobs much less intimidating for those less experienced. You do mention the sensors missing in the U.S. spec in the OPFs, but does the removal of the OPFs with the OAPs require any reprogramming? I thought that removing the OPFs will be recognized by the car and always trigger a code and check engine light due to the change in back pressures? As a side note, I will also check with my dealer on any potential warranty issues but I'm sure they will be ok with this mod as they previously told me that they are totally ok with any change unless it directly causes the car to break down and I think Porsche is much more open to mods than any other brand.

[@JetFuelOnly]

Thanks! No check engine light. It’s a non issue for sure. If your dealer said that you will be fine. Most are fine with exhaust mods in the US. However, asking them directly they may be less inclined to encourage it. :). Happy modding

[@JetFuelOnly]

Please not the lower title at 16:43 says “stock pipes” but it should say “Over Axle Pipes”

[@etc-and-more]

You make this seem so simple that even mere mortals with a set of jackstands and a nice collection of tools can do it. Going slow, what would you say for the installation? 3 hours? 4 hours? Watched the comparison video released in conjunction with this one and the sound is great, slightly different personality than the 981 but still wonderful.

[@JetFuelOnly]

Yeah that time frame sounds about right going slow. Some other brands have bolts instead of the studs and those studs can give people issues. I’m glad mine came an apart fine. You can probably get away without removing the muffler too, seen that done but also may be frustrating

[@Mellowbiker]

Did you ever get a good answer from Soul Performance about the dB levels? I'm at the same tracks you are, so it would be good to know if they hit 105dB... Reason I'm interested is that the PO of my car put on an Fi exhaust that sounds good above 3500 rpm, but drones terribly under that, so anything under the speed limit steady freeway driving is bad. Cheers!

[@JetFuelOnly]

No nothing unfortunately. There are a lot of variables to sound stations and tracks so it’s a little gray.

[@FabspeedMotorsport]

Love the video!

[@JetFuelOnly]

Thanks for watching! What do you think of the tight clearance with the frame on the driver side? Was that an issue with the earlier generation that was corrected?

[@FabspeedMotorsport]

@@JetFuelOnly Yes, those look like super early models and we have made a few changes since then. But we still think you will be okay with the clearance you have.

[@JetFuelOnly]

@@FabspeedMotorsport thank you for the feedback!

[@JOHNWAYNE1920]

Do you think heat coating works as well as that insulation? I have my headers and downpipe coated and it definitely makes a difference, but it's not as effective as that insulation you did. I'm just trying to lower underhood heat, but I think if i wanted to protect components, I'd go with the insulation wrap.

[@JetFuelOnly]

Honestly I’m not sure! I did a lot of research. Jet hot does work pretty well though. I remember almost able to touch some coated headers once.

[@katrinagwen]

Do you think this OAP install can be done with the rear of car on a ramp and wheels on without too much of a hassle trying to work on the triangle flange that connects to the headers? BTW, best how-to installation vid thus far on KZbin. By chance, you don't host the "Essential Tennis" KZbin channel, do you? You look and sound very similar to one of their presenters.

[@JetFuelOnly]

Lol, I’ll have to check out the Essential Tennis channel. Glad you liked my install. I would say no to the wheels being in. You want every advantage you can get to put the wrenches in the right angle. I would just use the ramps to pull the muffler then do each side one at a time on a jack/jackstand.

[@stevencahill3628]

isnt a tune mandatory once you install the oap? gives a better sound, better for the engine but prly voids your ecu warranty

[@JetFuelOnly]

Your points are valid but negligible. Definitely not mandatory. Generally nobody tunes after OAP unless they are in Europe and have monitors and want the CEL turned off.

[@mannysingh6618]

Are there temp sensors that connect to the OAPs?

[@JetFuelOnly]

No sensors on the North American car OAPs.

[@Bennbeckmanz]

gi guys how do these senmsors look like i cant see if mine has any ..

[@JetFuelOnly]

You mean the OPF filter sensors? You will see a pretty obvious cable and 1” diameter connector in the side of the pipe after the filter.

[@Bennbeckmanz]

@@JetFuelOnly thanks appreciate it, doesnt have em

[@MrGB1999]

Ummm we didn't actually hear the new set up with any revs or on a drive? 🤷🏻‍♂️

[@JetFuelOnly]

Sorry, I see your confusion, at the end of the video 16:43 the lower title says stock pipes but it’s the after market pipes as mentioned in the voiceover. You can hear more on my other video comparing the 718 to the 981

[@richardly438]

Does it feel faster than the oem?

[@JetFuelOnly]

Average go rating is 5-7 hp. Most people can’t feel that. But a good sounding car always feels fast!

[@angrydwarf6563]

Another great film/post. Now need to get I’ve axle pipes for mine! Really informative and the time / effort piecing together is appreciated. Enjoy the car.

[@richardly438]

@@JetFuelOnly thank you! I watched your video and bought 2 sets of bucket seat cover for my cars from Mr. Saadi. He is a super nice person and very knowledgeable.

[@BJSolutions]

Actually you might want to call it 982 GT4 instead of 718. The 718 is a name, not a nomenclature like 981. It's 981 Cayman GT4 VS 982 718 Cayman GT4.

[@JetFuelOnly]

Thanks, I’m aware and hopefully other viewers are too but 718 seems to have become the most common way to identify the new generation. But you are right!
