so, im going to remove the cat on my exhaust, to improve efficiency. as i cant afford to loose money on some bullhonkey environmental theory.... and while im at it. is there anywhere i can get complete stainless systems? has anyone made compelte stainless systems? or even non stainless? i hear it can add some power
cheers in advance

in holland we aren't allowed to remove the cat; that's MOT failure. a so called cat-replacer can be placed to fool the MOT man there is a cat under the car while it is a piece of hollow pipe instead.

i run stainless on my 340 turbo. lovely material to work with, with TIG you get really clean welds and after a few hard runs it gets a beautifull gold finish. it is quite expensive though, be prepared for high numbers if you start with it..

In Germany people do this (usually to old Mercs) once the 30 years "flat tax" threshold is reached and there is no financial gain from a cat any more. With newer cars it would be an MOT failure too, especially when the emissions are tested.

i looked it up online before hand and found out a car that is registered before 1st of august 91 doesnt need a cat. mine is h reg making it the latest possible registration date of 31st july. so it wont be a MOT fail

i'll have to ad to my post that it is a failure for any car from '88 or younger; or a car wich has a catalyst code on the vehicle documents. on cars from 87 or older there is no problem to remove it.

Yep you'll be fine to remove the cat on your car here int he UK when it's that old.

Indeed, it's in the MOT tester's manual HERE

There is a company in the VOC who do full stainless systems for 300's. Not ricer spec mind, AFAIK they are very close copies of the stock system in stainless

A man called Nev from F1-Moto does this kind pipe and his shop is near Brands Hatch if that helps.

thanks for the info mate you dont mind telling me the price? pm if you wish

You do not have a cat fitted to pass an MOT in the UK. The only thing the car has to do for MOT is pass the emissions test.

Sport exhaust systems - I'm sure I'm the only person offering full systems for teh 300 series in stainless.

If all other things in the system are changed to increase performance, and the exhaust is not, then it will restrict power.
Is probably closer to the truth!
