Hi all,just want to pick you guys knowledge,is there any advantage on de-cat my mr2 NA,and any advice on whats best way for me to go about this,including what to buy,and where from,will do work myself,if it gives me any advantages,dont worry about nct ,fresh one on car,and happy to convert back before next test.

Also fitted braided hoses yesterday,deff sharper brake feel,and easy to fit,only thing i learned on the fitting is on the rev4 the design is different on fitting them on the back,i needed to make a bracket on each rear,to have the breaklines fit snug,seems the rear original breakline has the brackets built into them,not a big deal just wondering if this is the same for all revision models,picked up brand new in packet brakelines for 55 euro delivered yesterday,off a lad selling his unfitted ones on adverts.ie,they where matt lewis racing breaklines.

Thanks for any help on this subject.

Putting a Decat in will do nothing you would notice in the butt dyno dept. I had one on the roadcar and there was no difference in or out. Then put it in the trackcar, again no difference power wise.

Little bit of noise difference but nothing noticeable or nice about it either. Now an induction kit will get a good roar going but most likely lose a bit of power due to taking air in from the engine bay, again it is so little that it makes no difference.

Braided hose wise, I got ones from Fensport and they had the right connections to fix into the strut properly.

Thank you for the advice and reply,good to no,as saves me a few pound finding out the hard way,was looking at the cat today,bolts holding it on,have magically disappeared,would have been fun taking them off to find out i was just wasting my time lol.
Thanks slipsliderg.

I've had a rev4 NA with decat and induction kit before and I don't know why but the celica st202 jap import 3SGE with just and induction kit and Stainless backbox on it feels a good bit sharper.

Possibly the hot air the mr2 would of took into the intake may not of helped and the jap imports usually have a few more bhp. I've been debating taking the cat out and would prob still pass the mot up here but as mentioned i don't know if I will gain anything and the induction noise above 4k is just hard to beat I don't want the exhaust noise to drown it out!

I had a rev4 n/a ... many years ago now that I think of it!! But it was completely standard apart from an K&N induction kit, the noise was awesome
