Hi all,

so I recently took my car in for an emissions test and the results were not too good, I was too high on NOx. Everything else we pretty bang on, just high on NOx. Basically suggesting my cats are not doing their job. The cats I used are just the ones FFR supplied with the kit, and I am guessing they are prolly not the greatest sets of cats to ever grace a cobra.

So for all you guys who have passed emissions, ideally with an LS3 or similar, what cats did you use? And were they good enough that you were happy to leave them in afterwards?

Thanks

Tim
