Fabspeed sport cats replace the restrictive OEM 800 cell catalytic converters with HJS Emissions Technology catalysts guaranteeing NO CEL (Check Engine Light) (on US cars only).

SOUND: Aside from the factory catalytic converters, the Audi RS6/RS7 has an extremely free flowing exhaust. So the best way to get more sound out of it is to replace the restrictive factory catalytic converters. These Sport Cats will make your Audi RS6/RS7 sound much more aggressive. It really brings out the V8 sound from the 4.0L powerplant. Pops, bangs and crackles will be much louder and sharper. Best of all, there is no interior drone whatsoever.

POWER: We dyno tested these Sport Cats on our in-house Dynojet. At the wheels, we saw max gains of +21 whp (or +25 hp at the crank) and +42 ft/lbs TQ.

FEATURES:

  • Fits all Audi RS6 / RS7 (C8) (2019+) Worldwide
  • Faster turbo spool and reduced turbo lag
  • More power across the RPM band
  • World’s largest HJS high-flow 200-cell tri-metallic catalytic converters guaranteed not to fail HJS German Imported H.D. Euro 6 Catalytic Converters 
  • Proven to support over 1500 WHP on McLarens No CEL (Check Engine Light) Guaranteed 
  • Laser scanned and CAD designed for perfect OEM fitment using AMETEK HANDY SCAN 700
  • Street & dyno developed and autobahn endurance testing
  • Constructed from high quality 14-16 gauge mandrel bent T304L stainless steel
  • Simple bolt-on installation, no cutting or welding required
  • All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

 

Why We Choose HJS Catalytic Converters:  HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the "straight pipe sound" while still being able to provide enough emissions scrubbing to prevent a check engine light.

    I know, I know, it's an RS6 how could one need more life in this car? Trust me, you just do. These downpipes on their own will do just that. They bring the car to life. Hearing the turbos spool and the engine growl as they should will bring a smile to you or for that matter anyones face. My car was equipped with the sport exhaust option but it just wasn't cutting it. Luckily fabspeed came up with a solution. The quality far surpasses the other options on the market and I really can't be more satisfied. I highly recommend this product, you won't be disappointed.
