  • Get rid of that nasty smell that you get with catless downpipes and that awful "rasp" that come with de-cat pipes. Unleash a deeper, refined rumble: This is primarily due to the fact that engine pulse waves can expand in the barrel of the main catalyst body providing

  • Near identical performance to de-cat Downpipes, along with a throaty sound and without the smelly fumes.

  • turbo spools up quicker for better throttle response and unleashes up to 20 HP and 20 TQ

  • Quicker spool allows the power to come in earlier with being able to hold it longer

  • can allow you to go stage 2 on a tune to allow up to 30-40 more HP and Torque

  • re-map using JB4 data log and take advantage of the higher flow for that push you back into your seat thrust around 2500 rpm

  • Over engineered construction for years of use
