The Sound

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, allows the engine to reach its full potential.

The addition of a 20 degree x pipe to the center section, raises the pitch of the exhaust, complementing the inline 6 scream, with a more visceral sonic experience. we also offer the option of a resonated (silenced) or non-resonated center section, to suit sound requirements.

The rear silencer section, working with the cars stock electronic actuated valve system, becomes completely freeflow on valve open, bypassing the silencer 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 either, F1 grade pre preg, carbon fiber, or Inconel double walled tails.

THE SPECIFICS

Cross Sections

Center section, 70mmOD dual.

Rear section, 70mm dual pipe (valve open), dual 57mm (valve closed), chosen for a balance of fast turbo spool, torque, and peak power.
