better off without one
of course a sports cat will give you better gains than a standard downpipe

Why are you better off without one?

For a start you won't pass an MOT unless you still have the restrictive centre cat fitted & a proper Sports cat will only loose you a small amount of BHP over a completey de-cated version.

If you can afford a sports cat then I would fit one and keep the car legal. At least that way you won't have all that grief at MOT time.. I honestly don't think you would feel the difference between a de-cat & a proper sports cat.

i have a RCM sports cat down pipe, as i didnt want the hassle of changing th epipe over every year for an MOT.

Car sailed through its MOT a few weeks back, so very happy!

Plus as Phil says, you dont lose much power over a full decat!

danog

does your de cat down pipe also replace the centre cat aswell or have you still got that fiitted to your sports cat?

ffs Pimmo why won't you take advice from people who have had the 1st stage of modding done already, like myself! Get the feckin 100cell downpipe!

Well perhaps fmp & myself will finally convince him to do the sensible thing... Spend the money & do it properly

see below ..

I'm getting loads of conflicting information.

pimmo2000

iTrader: (6)

See what I'm trying to balance up is the money to worth while.

If I get the downpipe, I lose the fuel pump and my new windows.

Is the down pipe with sports worth it ?? Will I see that much more from it??? or is it worth leaving till I get the more expensive mods.. turbo and such and the 2nd remap

Ok Pimmo I'm done with trying to help you. You can either take advice from people who think they know or from people who have actually done it. My 100cell DP passed MOT 5 times for me.

pimmo2000

iTrader: (6)

because you say you know doesn't help me .. everyone says they know..

The garage is telling me different ...

I'm listening and trying to understand, research reason and make a decision.

If you don't want to help that's fine, thank you for your advice so far, much appreciated.

bioforger

iTrader: (1)

If the garage is telling you not to bother with a DP or are trying to sell you a DP at £700 then they aint giving you correct advice or are trying it on imo. As I said before a remap is worthless without a decat, be it with a decat DP or a 100cell DP with a centre decat.

Ok after reading your other thread I have voted yes. The fuel pump is not essential for the state of tune you are going for.

Instead of repeating what has been said in the other thread I would strongly suggest you listen to Bioforger and Alan.

no offence intended but I am also struggling to understand why you are struggling with the concepts of stage 1 tuning with 5 years on this site and well over 7500 posts?

You will hear differing opinions regarding how to tune your scoob but the basic concepts for breathing mods and an initial remap are pretty much agreed accross the board on here. I would have thought you would understand this given your time and amount of participation on SN.

I hope you follow the advice and enjoy the car once its been done

There's been several people on here who failed an mot with a sports cat. They need to be really hot for the emissions test. But, there are a lot more people who pass with them with no bother.
I don't know of any garage who knows what they're talking about that will say not to fit one before a re map.
But, if you say you're going to be fitting a bigger turbo in the future, then you could do the cat then, as you won't be loosing any money in the long run, it'll still cost the same.
If you fit the cat later, it would give you some time to research what one to buy, which passes mots, maybe pick up a second hand one cheap(i got my whole Magnex system, including sports cat for £100!).
You need to think of time scales, if the second stage wont be for a while, you could be enjoying the sports cat on the car while you wait.
Decisions decisions!

is that aimed at me ?

i put that it is not guaranteed a pass as my car never with one fitted so i do know and dont just think i know

but as said by another member this depends on car, conditions and mot garage

Prodrive sportcat. I researched on here and couldnt find anyone that failed their MOT with one, whether it was a factory fit or secondhand.

Mine just sailed through the MOT with a prodrive one. It did also have the other standard WRX ones, in the uppipe and after the sports cat.

Sports cat, panel filter and remap made a big difference.

As bioforger above, I have had a Ninja Sports cat for 3.5 yrs and it has sailed through 3 MOTs no problems at all. In fact it sailed through each time when the car was cold also and I have no other cat on the system.

With the above Sports cat and a Magnex centre and backbox I achieved 273/273 with an Ecutek remap.

Recently swapped turbo and fuel pump, remapped again by Bob Rawle and achieved 325/320.

However, I have read some posts over the years with people who have had problems with Sports cats and MOTs - I would say the vast majority though like myself and bioforger have no problems at all.

Oh, and you don't need an uprated fuel pump unless you are running 320+ bhp. People do it running less power 'just in case' as it only costs 70 quid and its easy enough to fit yourself (I know as I did it on mine and I'm a numpty with the spanners).

That's no good its got a 200cell cat in it, very restrictive, that's why it's cheaper.

dnc

Agree here, 100 cell is better. Reliable ones are from Prodrive (though don't know if it will fit yours and may not be quick to get hold of) and I think the ones from Scoobyworld (from same manufacturer of the Prodrive one). I have Prodrive one and its always sailed through MOT even after a re-map. This is the only cat on my car.

As another poster said, if you intend upgrading turbo you would need another re-map then so will not cost any extra in the long run.

If you're quick you should get one by early next week (Scoobyworld - I've used them, very reliable, helpful and quick), sure someone will fit it for you - there is G Walker in Chester, Dyno Demon in Neston who specialise in Subarus plus Dave Ms mate in Liverpool (JGM GB thread). If you are able to do this in time for JGM visit, I'm sure you will be chuffed with the result; also though I'm sure you'll be happy with re-map of standard exhaust (until you go the whole hog later!). Have you got an after-market back box?

Agree with others' comments about £700 from your local garage.

Mine has a 100 Cell in the centre section (Powerstation/Miltek spec C) and no others and it will pass a MOT but only when very hot!

SirFozzalot

I managed to pick up a new Prodrive sports cat and the seperate (centre?) de-cat pipe (same as fitted for PPP) for a bargain price in the for sale section on here.

I personally couldn't be bothered with the hassle come MOT time of a full de-cat.

I run a RCM sports cat (100 cell) and has passed MOT x2 since fitted no problems.

Running 400bhp too.

I have an H&S sports catted downpipe and my car failed the emmisions test spectacularly and with flying colours. Good job there was another impreza they to do the test on for me.

lockley

mine just passed the mot without the cat and no sports cell i found removing the cat gives a get noise and releases lots of power with spool increased also

I found that with a bit of research i didnt need one as mine is an import and has no match on the vosa database so just a basic emmissions test is needed.

hes the info straight from vosa.
