718 Spyder / GT4 Gets LOUD KLINE Full Exhaust: Headers, OAP, Valved Rear Section

[@marcusedwards8248]

Softronic tune is a game changer. No regrets on my GTS 4.0

[@BuyYourBuild]

Cant wait for mine!

Looking forward to ECU upgrade feedback. Shorter 2-5 gears + lightweight flywheel would be a great addition to your build.

[@Zuffenhouse]

Throw a tune on that setup and you are nearly GT3 numbers

[@robertgregory1927]

Great job on the video! The exhaust sounds great. Is there an option just to change the mufflers on these cars? I have a 2021 Spyder but I want to keep it easy.

[@fullthrottle718]

Looking foward to hear your thoughts on tune. Are you planning to do a before/after dyno? I think the gains would be pretty significant since you already have the full exhaust system.

[@BuyYourBuild]

Might be worth testing. The tune usually takes a couple hundred miles to fully settle in from what I’ve read.

Not a fan of porchse but heard one near me and know obsesses with the spund of these i fotnto drive a 718 and didnt like the knotchy shifting and the weird auto rev thing it does, also in 1st it like assists tou and its not something im used to . But dang car sounds good

Starting to notice how unfriendly servicing that car would be 😅 9:22

Well you still won’t see me at the dealer paying $500+ haha

[@TarBoysWorldWide]

Yes, Kline sells just the rear valved section - shoot me a DM for a price quote!

@robertgregory1927, Kline muffler and over axle pipes must be changed as a set. Kline has the large pipes on top which is switched from the OEM configuration. Porsche OEM has the larger pipe on the bottom. I have had both stainless steel and inconel systems on my GT4. Changing both muffler and OAPs is not difficult. If you go with a different after market muffler you can bolt that to the OEM OAPs. I chose Kline because it mixes the exhaust from both sides of the engine with valves open or closed. I think this is what gives a very refined sound. OEM and many other after market mufflers only route 3 cylinders out each tailpipe when the valves are open. This does not sound good in my opinion. The following video is a few years old but does a good job explaining different exhaust options for 718s with a 4 liter engine. kzbin.info/www/bejne/Zp2yaYWghsmVf5o I hope this helps.

@ Ed, thank you so much for that information. I really miss my previous 981 exhaust sound but I think between cost and installation I’ll just keep it stock.
