Tarmac Sportz Nissan 350Z VQ35DE (03-06) High Flow Cats HFCs Sports Cats

Tarmac Sportz High Flow Cats, Sports Cats, HFCs, Catalytic Converters  

Whatever you want to call them they are here and they maximize air flow to give your DE more power, our HFCs are a Euro 200 Cell Spiral Wound Metallic Substrate for maximum air flow and performance.

You will notice an increase in noise when fitted to your car, they become especially lively around 3k revs, they can be fitted with forced induction vehicles however no warranty is provided and we would recommend decats.

Our HFCs come with an extra 02 sensor bung should you want to run wide band gauges, on average you should see gains of around 15bhp with HFCs, check out our power packages as well, Plenum spacer, panel filter and a set of HFCs will usually see around a 25bhp increase

They come with a 2 year warranty against product failure, but please note this does not include failure of emissions test as there are too many outside factors that can affect the outcome of an emissions test. HFC's are on the borderline of passing emissions and are primarily designed for off road use. 

As with all HFC's they will need to be red hot prior to a test and your car should be remapped to make sure they are working to the best of their capabilities and the 02 sensors are reading correctly to avoid any over fuelling.

PLEASE NOTE: As with all HFCs, there is a possibility that HFCs will bring up an Engine Management Light,

CEL Eliminators usually work but this is not always the case,

We recommend getting the car remapped after fitting to remove the light if the EML persists.

PLEASE NOTE: These will not fit the HR Engine, please see our other listing HERE
