Got a my00 uk scooby. its got a standard exhaust with both cats in it still with a remus back box. looking at changing and getting rid of the standard one,but dont want a non legal one that i have to put the cat back in for the mot,not to loud either.
Been quoted:
back box £250
centre 1 £90
centre 2 £90
downpipe £450
all gaskets £80
up pipe £125

with vat an labour on top it woirks out at a whopping total of £1827
is their anything else that is cheaper? that will also give me more bhp??

Also what performance air filters are best? What bhp gain would i get from this??

Any help and advice would be great.

I thought it was only the newage models that have 2 centres sections.

Scoobyworld do a much cheaper Cat downpipe for £299... http://www.scoobyworld.co.uk/catalog...products_id=76

A straight through centre and back box is around £90 and £250 respectively (inc VAT). Again I think it is just the newage models that have a cat in the uppipe so you may be able to save some money there as well.

I got my exhaust from Hayward and Scott... http://www.haywardandscott.co.uk/res...sp?category=13 and they reused my old gaskets without any issues.

As regards filters, I'd look at either an STI one or a Green panel filter, and as the green one is cheaper I'd go for that!

superd thanx for that, that is a big price difference! hmm,as with regards to how many centre sections on a my00, i have no idea, thats what i was told at the scooby specalist
what sort of bhp power increase would i get i i were to change to a green panel filter?

Hi, the newage Imprezas have 3 cats, and as you say the classics have 2!. Try ebay for a exhaust system they go quite cheap on there, and you could probably get any old garage to fit it for you. Personally I would only remove one of the cats it will still give you a BHP increase, but you wont have to mess about at MOT time. Also if you de cat the whole car you are wondering into the realms of a re map, otherwise you may find you have cel issues.

With the scoobyworld sports cat d/p mentioned above there are no mot problems.

o right, so what one is better to replace the down pipe and section that is shown on the link, the ninja, or change the other sections that is shown further down the page on the scooby link (ninja)??

With a classic you have the back box a mid section cat and a downpipe with cat the mid section can be changed for a straight through pipe or one with a resonator if you want to keep the noise down both options remove the cat then you have the downpipe with a cat in which can be changed for straight through no cat or sports cat (100 cel ) which will pass MOT if you can do the lot mate some will quote 20-25bhp gain and better spool up.
