These high-flow cats are direct replacements for the OEM catalytic converters on the Audi TTRS. They are constructed from 2.5" mandrel bent 304 stainless steel piping and Magnaflow stainless steel catalytic converters. Flanges are CNC waterjet cut from 304 stainless steel and TIG welded for perfect fitment. Piping is slightly reduced to fit OEM band clamps. Catalytic converters are 200 cell/inch metal core in spun stainless steel bodies. Gaskets & hardware included.
Fitment is identical to OEM catalytic converters. Installation is simple. No permanent modification necessary.
TTRS test pipes deliver a deeper exhaust note and mild horsepower gains throughout the power band.
