  • Thick 8.5mm welds to prevent leaks or cracking

  • Argon gas back purged welds for penetration and seal =Long life

  • CNC T304 flange and V-band ensures a tight factory fit

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

  • 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 25 HP and 35 TQ

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

  • 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

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