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 worlds 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 system's.
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 freeflow 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 rpm's. 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!
De-cat variant, 48hp gain @ 6500 rpm
73nm gain @ 3800 rpm
