Got this dump fitted recently and upgraded to a Stage 2 tune.
Volkswagen Golf 2.0T GTI Turbo Dump Pipe - Empire Performance

Runs great, however I'm getting noticeable fumes coming from the exhaust.

Any recommendations for a CAT to retrofit?
Found this one based locally in Perth:
Performance Car Parts - 3" Inlet/Outlet 4" Core SS304 High Flow Metal Cat/Catalytic Converter (100 Cell/CPSI)

Not sure if 1 x 100cel CAT would be sufficient to reduce fumes being that the stock dump has 2 x 400cel cats.

Cheers
