Kline Innovation – Cat-Back Systems. Fits Audi RS5 B9/B9.5.
The Audi RS5 is a beast that perfectly balances elegance and raw power. With its 4.2L FSI V8 engine churning out a thrilling 444 horsepower, its a marvel of modern engineering. But lets be realtheres always room for improvement. Thats where the Kline Inconel full exhaust system comes into play. If youre looking to enhance your rides sound and power response, this setup is a game changer.
What really grabbed my attention were the factory manifolds. Honestly, they felt a bit restricted. The crushed and stunted primaries, along with the lack of a proper performance collector, were holding back the true potential of this engine. And lets not even get started on the 400 cpsi catalyst sitting right in the power-sucking scavenge zone. It was clear that a significant upgrade was needed. The factory design is understandable, given the tight space between the heads, block, and chassis, but it also meant there was a lot of untapped potential waiting to be unleashed.
Swapping out the stock cats for long primaries and motorsport-grade collectors was a game changer. The difference in torque and power response was immediately noticeable. Plus, the sound? Its like the car finally got the voice it deservedbalanced yet aggressive, with rev response that puts a grin on your face. Kline even offers an option for fitting 100 cpsi cats to the downpipes for those who want to push the limits even further.
Next up was the center section. Adding a 20-degree X-pipe made a world of difference. Since the RS5 has a cross-plane crank configuration, relieving those pressure spikes from the uneven firing pattern really amps up the power. You can choose between a resonated (silenced) or non-resonated center section, depending on how much noise you want to unleash. Trust me, its worth considering.
Now, lets talk about the rear silencer section. Kline crafted lightweight, valvetronic rear silencers that work seamlessly with the car's stock vacuum actuated valve system. When the valves are open, its a free-flowing, aggressive sound that makes you feel alive. But when you close them, the exhaust gases take a detour through chambers designed for low RPM torque, keeping things quiet during cruising. You can choose between a mild sport option thats not too loud under valve closure and a stock-quiet option for those peaceful drives.
This exhaust system fits various models of the Audi RS5 from 2011 to 2024, including the Sportback versions. If youre serious about upgrading your ride, this Kline Innovation Valvetronic Catback exhaust system is a solid choice that delivers both performance and that exhilarating sound you crave.
