These are high flow catalytic converters to suit the VE-VF Holden Commodore 3.0L and 3.6L. The stock cats are 400CPSI, installing these will allow for less restriction and opens up the engine for higher horsepower potential. Bolt on upgrade will give you a 10-15HP increase.
These are essential in our Stage 2 Tuning Options, especially if you want that really nice crackle tune we do. Please see the below video. These are true bolt on, no welding/cutting required if pairing up to an Xforce catback or other similar brand.
We can fit these starting from $200 in our workshop.
We do custom tunes starting from $600 for these and $50 for the Crackle add on. Contact us today for a performance package.
