I need a 182 mani and cat, but cba the 10 hours labour getting one of these fitted!! Even though they are epic :) I think I have a de-cat mot sorted now, just gotta leave the car with him for a week to do that, fit my matched inlets and fuel line so its no longer held on with cable ties :/

switching 172 cats is just disgusting work for people with childish hands. imo it is worth the hassle to upgrade to a 182 mani, cat/decat exchange is about half an hour then...

You can't just use a 182 cat though can you? You either have to buy the K-tec sports cat or decat.

The limit for mine is 0.20%...mine was 0.17% and that was at the 3rd attempt I think! Pulled the sensor out a bit.

Seems mine is poorly and running very rich :(

IT should only be about £40 to change it...Dont you remember how much we paid when we swapped Yozza's and Stealth?? £90 for all that I think?? :S

That's a seriously strict limit!!!! doesn't surprise me in the least that it's hard to achieve. Seriously rich sounds like quite an over-statement though. Remember it's not that long ago that cars didn't run cats and the MOT CO limit was 3.5%. If you have a big exhaust, you're probably just getting gas reversion causing oxygen to be sucked back in. Wet rag up the tail-pipe at the same time as the probe to reduce the exit apperture can sort this out and give a true reading

Il double check my MOT thingy me bod but I swear the limit said 0.20%. Good job I put my cat back on otherwise I would of been well over!

Exhaust is an HKS Superdragger off a standard evo8 so yeah its not small!
