We have 3 gas analysis machines at work and the emissions are better than original and well under the specifications. I spent allot of time on fuel atomization and tuning to make that happen and also to make the CAT's live.

On that side I only use SMB & Performance Weaponry Catalysts, this has been a long term test project between us on this and their offering has delivered in power and durability and ultimately measured performance against known iconic cars it's nice to have the real engineering data on their abilities too showing the effect of pressure and turbine response and to a greater degree the power restriction in running such a device in a car of this proven power and performance.

Last time I checked the CAT it was excellent, I believe the only thing that kills these types of things is long term running on non ideal *chemically correct* mixtures at low speeds (especially cruise) where the rich mixture has time to react in the body and thus overheat and kill it. Full throttle and high gas flows dont kill cats as there is not enough time for the reaction to happen and thus little more temp build up apart from what is in the system at the point anyway *and this is reflected in the beginning and end AFR value you measure*.

Glad you like it I absolutely love it was always my goal to equal Ferrari F40 performance, infact its better than allot of modern day alternatives... even the famed ZRI that only generates 0.48G accel at 81mph or 130kmh V's my RICESP @ 0.52G
