maz77 Posted December 25, 2009 Posted December 25, 2009 just vouching for experience from members on universal 100 Cpi Motorsport Cats I came across Hoffmann's universal 100 cpi (cells per square inch) Motorsport Cat. I know they are not MOT friendly but is there anything with better flow thats track/motorsport approaved. thanks in advance Quote

Ian Posted December 25, 2009 Posted December 25, 2009 kinetix, berks envy's own brand. are all racing cats all with similiar CPI's Really? Theres no mention of the rates on the Envy site Maz, I had 100 cell race cats on my car & passe an MOT with no problem, they are now on Nurrishes car They were a lot more expensive than the other makes but well worth the money Quote

I am looking at 100 c as they offer the best flow bar decats I believe Quote
Ekona Posted December 26, 2009 Posted December 26, 2009 A 100c cat will pass any MOT without a hitch, I've run them on previous cars too In my experience changing the OEM cat to lower CPI ones makes precious little difference as OEM cats flow sooooo much better than they used to; however I believe it was Adam who corrected my statement last time by saying that there was a noticeable difference on his car when he swapped over, so perhaps Nissan have used more restrictive cats on the Zed than other manufacturers use.
