That is all you would need. As for emissions...it is supposed to pass them according to them. Might want to check with them and see what happens if you fail emissions.

i gotta break it to you gruntly2006, my stock CAT went last year, but instead of buying a mazda one, i've got a TVR Race spec CAT, and a full custom stainless system on my 231bhp model, but mine fails the emission tests miserably, but it all depends on who you know and where you go whether it'll 'pass'. You gotta remember rx8's are 'high emissions' car to start with. I've had mine on for about 6 months now and its great, backfires like hell (like flames an ****!) when i give the throttle a poke, sounds awesome too, and if you do buy a custom exhaust/CAT or De-CAT it altogether the engine management light may come on warning of excessive emissions, but just buy a ECU scanner off ebay to solve that prob, My advice would be to find a local performance specialist and let them take care of your exhaust/CAT, my place is called Urban Racing in St Helens (Merseyside, UK) the finished job looks great, great after sales service too, hope this is of some help :-)

hi gruntly

my CAT went at 62000 odd miles, 16 months ago. happened a few weeks after i bought the car so used car dealership replaced it under good will as mazda charge £1100 for an rx8 CAT.
my engine light came on driving home, i had just got it MOT'D and it wasn't crackling as normal as i have a motoria stainless steel cat back exhaust which normally sounds great.

recently my coils went and i got them, plugs and leads replaced, car drove like new for a few days, but i noticed some hesitation slightly at 4-5000 rpm a few days after. as i red line its like the CAT feels a bit stuffed, then the power comes on at about 6500rpm to 7000rpm and above as normal.

not getting any dash lights, my scan gauge II says no recorded codes, dunno what it could be. i did have to get the car tow started as the mechanic doesn't really know rotaries but could change the plugs,coils and leads ok, may have got flooded and this is not good for a CAT either. My CAT has only done about 10000 miles so, if they go that quick then they are ***** no harm to mazda and yes they should be covering them like the USA.

I emailed honest john motors about if there is a warranty like the US's 80,000 mile warranty, but there isn't any as its part of the exhaust and most warranties on cars don't cover them.
I have signed up to warranties direct who sound very good and for a bit more will cover the CAT. I like the sound of this super CAT and would see about getting one if someone in the UK can verify it will pass the MOT etc. this part is too expensive to keep replacing and mazda should have a CAT that can cope with the high emissions/heat etc of the rotary. alot of people don't have bags of money to pur into a car, I for one am very disappointed with this and they should be covering their CATs with a suitable mileage warranty, when its bought new etc.

Look about a breakers yard to see if you can find one as the US CATS may do as their emissions laws would sound like they are quite strict and so would get you through the MOT.

let me know how you get on.
