Which mid section to get???
#1
Hi folks,
Just a quick question on mid section for MY99.
Already have a SS backbox which is great.
I do not want to do too much to the car as it is still under warranty.
I was thinking to fit a mid section and ITG filter
Does fitting the mid do anything for performance or is it just for noise.
Also what one is recommended, SS, Scoobymania or Magnex. The SS is approx £30 more than the other two. Is it really worth the extra expense.
Any advise would be appreciated.
Cheers
Kwack

You should have *** mid section, as it is the same diameter as your back box.
essentially they are all just straight stainless steel pipes, not muc in it.
Performance wise I would expect nothing.
Might make it a bit louder but not a lot, since it wont ave a resonator cavity which quietens but restricts a small amount.
If you had a cat there it would improve performance, but I have no idea if you do or not.

KWACK either magnex or ssport will do the job nicely, i have ss downpipe magnex mid ss backbox, got the magnex c/pipe because it was cheaper than ss item,and i could get it that day in nottingham.tommy

Kwack,
Cheers for the wheels!
Mine has the full Magnex, downpipe on the way soon as well. The Magnex centre has a resonator box which will reduce noise if you are bothered about it. Its pretty quiet in the car. Both are same grade of stainless so there really is little in it, apart from wedge. Might be nice to keep it all the same though.

Are you getting a Magnex down pipe?
If yes, when you get it installed can you let me know how it goes. What extra performance you feel or if you go on a rolling road the figures and how much noisier is it.

kwak,
You DO have a centre CAT as standard in your MY99, so replacing the centre section will help slightly with performance.
Magnex seems like the most popular choice among Scoobynetters, so I'd probably go for that.

Can anyone confirm that I can put a P1 centre section onto a standard UK MY00 without any problems?
I just want to loose the cat in the centre section and this seems to be a cheap way of doing it.

Cheers Mellow - you know I'm easily confused! Thanks for the mail btw - I now have a shiny new "****". The wife will be pleased.....
Whilst I'm nearly sold on the P1 pipe can someone quickly talk me into a Magnex one? Does it have a resonator or is it a noisy bugger? Will it just fit straight into my system? I must admit I thought the P1 centre pipe was the one Prodrive used in the PPP upgrade. Anybody know for sure?
Cheers chaps.
PS. You can get P1 centres from main dealers with a bit of "gentle" pressure! They're about £120 - how much is a Magnex?

Simon, definately...definately....definately...that's a yes in case of confusion
It fits exactly and apart from the "cat" it is identical to a MY00.
Hope you received your "****" ok, recorded delivery yesterday lunchtime.

Chris

Don't waste your time with P1/STi mid' sections. They may well be cat' free, but are still very restrictive.
The Magnex gave circa 10bhp/ftlbs over the standard STi mid' section, on my, and other cars.

Is it only the magnex that has a resonator or do they all come with one?
Is there any benifit for not having a resonator?
Can someone list the ones that do not have a resonator.
Thanks
Jamie

Kwack,
A Magnex will cost about £110~120, and yes it does have a resonator. It's pretty quiet, and gives very good results. I ditched my STi4 mid' for one (same as a P1).
If for some strange reason you must have the P1/STi mid section, ask around, you should be able to pick one up for next to nothing, from someone who's already changed theirs.

Magnex do two types of c/c. One with resonator c£100, one without c£55. I've got the one without and am pleased with it. Not noticeably louder, but slightly better pick up and runs more freely at high revs.
Overall Recommended
Send me a mail if you want details of a supplier (I had trouble finding one - a lot of suppliers are only aware of the Magnex c/c with resonator)

Just to support the other people who say don't bother with a P1 centre section.
Posted by Pete Croney:
"Centre Cats fitted at factory...
All UK.
All WRX (import)
All STi up to part way thru Version 4 production
Most 22B (can't tell without looking into the pipe)
All 22B UK
All P1
All WRX01
No STi 5 or 6"
As you can see then, there IS a CAT in the P1 centre section, so it would be silly to get one of these instead of a de-catted (as well as stainless steel) ScoobySport or Magnex example.

Sorry Scoobysnacks,
But there is not a cat in the P1 centre section,if that was the case why would the P1 need a d/pipe cat with higher precious metal content(quote from Mike Wood)sounds more like Broquet being added if you believe the hype.(Flame suit ready and primed)

Scoobysnacks,
I'm 99.99% certain that a P1 does not have a cat I don't even bother to look any more when I'm changing whilst working at Scoobysport 3 days a week LOL.
By my reckoning if the P1 is based on a Version 5 which does not have a cat why would they go to the trouble of fitting one when they can't even be bothered to remap the ECU?
I'm sure some P1 owners on here have their old centre sections around (Arron Bird if you are still out there) and can confirm this.
Also the 99MY PPP uses a STI 5 centre section which they could be taking off all the P1's when they fit the cat....very unlikely.

I was at a rolling road session about 2 years ago.
A car ran with a standard backbox, and then an aftermarket one. The gain was about 2-3 bhp, although heat soak may have robbed a few more bhp.
As I was told, if you want to buy an aftermarket backbox, buy one you like the sound of!! If you want more performance, lose the cat(s)!!
Andy
PS - I have a ScoobySport downpipe and backbox, along with a Magnex centre with a resonator. And it is quiter than a full SS system. It's also quiter than a car with ScoobySport backbox and downpipe, along with a Magnex straight through section.

Didn't I start a great debate here.
Good point Peterperfect, why does a SS pipe cost alomost twice as much as Magnex, Sccobymania. Could it be to do with the 25 years warranty ???
Who knows, anyway thanks for all the advice going to pick a SS mid on Saturday and fit the ITG at the same time.
Thanks

When looking at 25 year warrantys, always look at whats backing them.
If its not backed by an Ins policy, its not that much of a guarantee. If the company folds, so does your guarantee if they are covering it themselves.
Some companies (none that I know of on Scoobynet I hasten to add) work on this. They produce shoddy "guaranteed" goods and services, then fold the company and start a new one.

p.s. I love my Scoobyport mid and backbox.
Apart from when crusing at 80mph when I think its exactly the resonance frequency.
(Not that Ive ever hit 80 of course officer!!!)
