However, we at Kline take perfection very seriously, and as a result felt we had to take our GTR exhaust to a whole new level. How could we achieve this? With a combination of elegant design, uncompromising materials, acoustic, and fluid dynamic modelling.

THE INNOVATION

The 3.8l v6 engine being mounted at the front of the GTR, designing and building an exhaust with a high standard of sound and performance might be considered a fairly easy task. However, we at Kline take perfection very seriously, and as a result felt we had to take our GTR exhaust to a whole new level. How could we achieve this? With a combination of elegant design, uncompromising materials, acoustic, and fluid dynamic modelling.

Setting the benchmark, the world's first GTR exhaust made entirely from Inconel 625 formula one grade material. Inconel is very light weight, our GTR system being one of the lightest resonated 89mm system in the world. Inconel is also incredibly durable, with high thermal and chemical stability, and will not fatigue and crack over time like titanium systems.

THE SOUND

Removing the quad 400 cell catalysts, and replacing them for either de-cat pipes, or 100cpsi catalysts, increases and enriches the sound, as well as improving torque and power response. replacing the resonated y-pipe for a free flow variant further accentuates the sound as well as lightening the exhaust. enlarging and simplifying the rear silencer section, we were able to essentially consolidate the volume of the 3-silencer factory setup, into a more efficient twin rear silencer design, further lightening the setup. the rear silencers have been volumetrically tuned towards removing bass drone at cruising speeds, while giving a rich aggressive vocal at high RPMs. Built from Thin sidewall Inconel, with high latent resonant frequency, the sound is accentuated in the treble frequencies, giving a higher pitched more aggressive sound when you need it. The Inconel sound really is quite electrifying!

PERFORMANCE

De-cat variant, 48hp gain @ 6500 rpm
73nm gain @ 3800 rpm

Excellent pillow. Soft but medium support. Fell asleep on it right away and it stays cool. Like sleeping on a cloud.

A Good Night’s 💤
Size: Standard (Mid Loft), Number of Items: 1
I’ve bought many pillows over the years and this pillow is by far the best for me. I am a back and side sleeper. Finally wake up without a headache or neck discomfort. I bought the medium standard. Just the right consistency. Not to soft not to firm. Stay cool pillow.

Confortable

Excellent support. Always fluffy. It does have a smell but as recommended I let it air out for a day. I also washed the cover and had no issue.

So comfy
Size: King (Pack of 1), Style: Standard Loft (4" - 5")
I spent time looking up/watching videos on pillows for neck pain and this one comes up a lot. I’m someone that used to wake up every few weeks with a stiff neck so bad it could make me cry at work. I haven’t had that happen once after months of using this pillow. I look forward to laying my head down on it every night. It’s a luxury experience every time. I think what it does so well is maintain its shape. You can really squish it up how you want and it stays there even after hours. Moldable but somehow still firm. It’s expensive but to me the value is there because I no longer get crazy neck pain from sleep. Worth trying it out for sure. Btw I was stuck between this is and Purple brands couple top end options. I never got around to trying them because I tried this one first and was very satisfied! Feb 2026. Still use it every night and it's still protecting me from neck pain I used to get from sleeping. It's held up amazing. Hope to use it for many more years.
