Audi RS4 B8 Catalytic Converters replacement

The customer first brought his Audi RS4 to us for a Walnut Blast and Dyno run, The results of the dyno run showed heavy timing pull at high rpms and nearly 100bhp down on power!!, Further Investigation we found the catalytic converters had failed and turned in the casing of bank 2 causing a restriction in exhaust flow. Removal of the Engine and gearbox assembly is required for the replacement units.

New Audi Catalytic Converters fitted and Engine and gearbox re-fitted into the car we then went on to the dyno for another power run, +74bhp more over the previous dyno run with failed catalytic converters! no timing pull and revs to over 8,000rpm no issue!
