Here at Kline, we felt that the factory Aventador exhaust was not special enough, it does not live up to the raw nature of the supercar.
The basic Kline sound requirement was to create something that would truly scream at high revs, while being almost stock quiet at cruising speeds.
Under valve closure, the exhaust gasses are diverted through a series of chambers and acoustic sections to completely remove any drone. At valve open, the exhaust becomes completely free flow for optimum performance and sound, the gasses only passing through our trademark tight radius x pipe, to effectively raise the pitch of the exhaust note. The exhaust note on valve open is seriously incendiary; the x pipe raises the pitch of the exhaust note into a raucous aggressive vocal for that "demon screaming" sound!
Removal of the catalysts, and addition of a completely free flow system under valve open, results in optimum efficiency from the exhaust, and some moderate power and torque gains. 23hp and 29nm power and torque increase. (The gains listed, are after air fuel ratios have been compensated via software for the exhaust upgrade. To experience the full performance potential of the exhaust upgrade, an ecu tune is recommended.)
