AMG GT downpipe and midpipe

This Mikes Custom Cat-Delete Downpipes and Midpipes eliminates the catalytic converters for maximum exhaust flow for the AMG GT/AMG GTS with M178 engine.

Key Features:

  • 100% hand crafted in the Russia from premium French 304 Stainless Steel - flanges and O2 bungs included!
  • No Questions Asked 5 years Warranty!
  • Mandrel Bent 84mm-76mm piping. Smooth transition to the exhaust system
  • 100% TIG welded for better quality welds
  • Precision CNC V-Band flanges and quick release clamps
  • Exhaust hanger like factory that helps support the exhaust system
  • Compatible with the factory or aftermarket exhaust systems
  • Includes all hardware for complete installation
  • Torque gains of 80wtq average (stock boost) up to over 300 wtq (software upgrade)
  • HP gains of 25whp average(stock boost) up to over 180whp(software upgrade)
  • Better throttle response and faster turbo spool up times
  • We do NOT grind/polish our welds as some other manufacturers do. Grinding welds compromises the strength of the weld, and can lead to weld failure!

Restrictions in the exhaust system robs horsepower and torque especially on turbocharged cars. Thus, removing as much exhaust flow restrictions will increase horsepower and torque significantly. The factory catalytic converter found in the factory downpipe is a big culprit of this and is a major exhaust flow restriction. The factory catalytic converter is made up of catalyst material formed into "honeycomb" weaves. Exhaust gas must pass through these tiny "honeycomb" weaves on their way to the exhaust system thus causing a major exhaust flow restriction. It also causes turbulence after the catalytic converter which causes the exhaust flow to slow down (which increases restriction). By replacing the factory downpipe/catalytic converter with our Catless Downpipe amd Midpipe, more power is unleashed! You will feel the difference instantly.

Our Catless Downpipes and Midpipes is constructed out of 100% 304 grade stainless steel and utilize mandrel bent piping. They are 100% TIG welded by our in house fabricators and built in the RUSSIA. The factory turbocharger turbine housing utilizes a V-Band flange which we have duplicated and CNC machined cut out of billet 304 stainless steel. Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods. The O2 sensors is positioned at the factory location.
