MONSTER SERIES :Ultra High Flow 5" Catted Downpipe


  • Get rid of that nasty smell that you get with catless downpipes and that  awful "rasp" that comes with no cats on turbo engines

  • Ultra high flow metallic 200 Cell catalyst substrate ensures you flow 98% as close to catless

  • Monsterous deep aggressive tone, better than a full exhaust in some cases

  • Smooth out your exhaust tone compared to catless and enhance the      sound of your stock setup, sounds amazing!

  • 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

  • little to no horsepower or torque loss compared to going catless...why compromise?
