Fabspeed AMG GT/GTR/GTS Sport Cat Downpipes (15-21) (FS.MER.GT.SC)Constructed from T304L high quality stainless steel, Fabspeed Motorsport AMG GT GTR GTS Sport Catalytic Converters offer premier quality catalysts by utilizing HJS Germany Tri Metallic 200 cell catalysts.

Constructed from T304L high-quality stainless steel, Fabspeed Motorsport AMG GT/GTR/GTS Sport Catalytic Converters offer premier quality catalysts by utilizing HJS Germany Tri-Metallic 200 cell catalysts. We perfectly match the sound expected of the AMG GT cars by dramatically improving sound and power throughout the RPM range offering a much-needed solution to the boring factory exhaust. Using only certified high-performance HJS components imported directly from Germany, our system eliminates all risk for black market, grey market, or counterfeit HJS catalytic converters from other companies. Increase the muscular twin-turbocharged Mercedes Bi-Turbo sound and reduce backpressure allowing for much quicker turbocharger spooling and transient turbo response. 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:

Optimized for maximum performance and sound, the rumble at idle is significantly improved and adds a much-needed pop and burble on the downshifts. Now, for the good part. On throttle, your AMG GT car is noticeably more throaty and alive with completely free-flowing sports car sound exhaust notes and completely drone-free.

POWER:

We dyno tested these Sport Cats on our in-house Dynojet. At the wheels, we saw max gains of +10 who and +10 ft/lbs TQ.

FEATURES:

  • Fits all Mercedes Benz M178 AMG GT/GTS/GTR (2015-2021) vehicles worldwide (Not Black Edition)
  • Faster turbo spool and reduced turbo lag
  • More power across the RPM band
  • The world’s largest high flow 200-cell Tri-Metallic catalytic converters for the AMG GT GTS/GTR
  • 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
  • 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


PURCHASE DISCLAIMER: Fabspeed Motorsport does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. Fabspeed Motorsport will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b). This includes software, known as tunes, that reprogram a motor vehicles electronic control module to alter engine performance and enable the removal of filters, catalysts, and other critical emissions controls.

 

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 won’t 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. If you'd like to learn more, watch our video about HJS catalytic converters.

 DISCLAIMER: This product removes the OEM catalytic converters from the vehicle, and as such, is strictly intended for closed track events and off-road use only. This product contains a High-Flow Sport Catalytic Converter solely intended for track and race cars as it is NOT California Air Resources Board Certified (CARB) and not EPA certified. You are hereby informed and warned to check your local, state, and federal laws before buying and installing these or any aftermarket parts to be sure whether usage is in violation. All installation-risk and use-risk is borne by the end-user and installer of these parts.

Fun ball for dog
Color: light blue
This is a great toy for the dog. So far the ball is still complete by chewing several days. I have to say it is perfect size for the big dog. The ball is light and also has a changeable light and models.
