AUDI RS5 2018

The RS5 with a 2.9 litre v6 biturbo engine, producing 444hp is a beautiful example of modern engineering. As with all turbo induction engines, the potential to improve the sound, and power response through exhaust tuning is substantial!

Kline Innovation

Replacement of the stock 600cpsi catalysts, with either high flow HJS cores, or de-cat pipes, opens up the sound significantly, as well as drastically improving turbo spool for increased power, and reduced spool time. This coupled with the twin 70mm dual oversized down pipes, and 89mm oversized center section, as well as flow optimized pipe free of compressions, allows the engine to reach its full potential. An additional laser cut aluminium cross member is included with the exhaust, to allow for the oversized center pipe.

The rear silencer section, working with the cars stock electronic actuated valve system, we crafted a set of light weight, valvetronic rear silencers. on valve open the system becomes completely freeflow, for optimum performance, and aggressive sound. under valve closure, exhaust gases are diverted through a series of chambers and acoustic filled section, tuned towards low rpm torque, and a very quiet volume at cruising speeds.

The rear section is finished off with a set of quad carbon fiber tails, manufactured in house from pre-preg F1 grade carbon fiber, with inlaid branding.


The Specifics

Downpipes 70mmOD dual, and single 89mm center pipe.
Rear section, 70mm dual pipe, and quad 63mm, chosen for a balance of fast turbo spool, torque, and peak power.
