No need to worry about boost creep with 2.5" system.

The STI RA if it is a jap ( JDM ) import then it will be a 3 part exhaust like the classic design , a UK spec STI will be in a 4 piece exhaust.

Quote..Also, as I live quite near to H&S I'd like to drive down there and have the parts fitted. How much would fitting be for a decat down & centre pipe for a classic (MY98 Type R)?.


We would only charge for fitting the down pipe which is £75 the rest is free fitting :-).

i'm maybe putting in a late bid for de-cat downpipe and/or de-cat centre - but need to ask some questions since the search function is down - i have a MY00 classic wagon with an H&S backbox only. it's already quite loud at motorway speeds but i could bear a little more.
1. will de-catting either definitely mean i fail the mot?
2. if i only went for one option, which is the better to de-cat for power gains?
3. will noise be substantially increased with both? is decatting one pipe going to prove louder than decatting the other?

thanks for anyones help!

V4JDMSTi

iTrader: (2)

full decat will most likely fail the mot unless you know the tester and he will "pass" it. in the next few months it's not going to be possible to get a £50 pass. but if you keep the down pipe and swap it back for the mot and then take it off once it's passed who will know?

the downpipe cat is best to remove for power but leaving the centre one will still make it hard to get it through an mot. it's further down the exhaust line and you'll have to get it super hot. drive like you stole it for 1/2 hour should do the trick but might not help your licence

yes it will make it louder but you could go for a resonated centre pipe which will take the edge off it. as for which one removed or left to make it louder i'm not sure. with a decat downpipe you're likely to hear the turbo spool up whistle more.

i think what i've said is about right but i'm sure someone will correct if not.

cheers

matt.

Ian's reply on Page 1 Post 18 sums it up pretty well.

I am getting the high flow 100 cell catted down pipe that has only a 2 BHP loss over the decatted down pipe.Junk the centre cat & fit the straight through pipe.Then MOT is straight forward as the cat in the down pipe gets hot enough to pass with normal driving.

Saves all that hassle of flying up & down the road outside the garage till he's ready to stick the probe up yer back end.

Also saves the hassle of swopping down pipes or double cat centre sections that some garages use.The risk of snapping studs & getting a gas tight seal each time is not worth it IMHO for the sake of 2 BHP.Also if you fail a roadside check you have all the hassle of another visit to the garage to get your papers stamped.

Ian[/QUOTE]

the other two will help make a de cat pipe.

Im going to fit a 3" high flow cat somewhere in the center section or straight after the down pipe. 4 bolts no fuss swap in 5 minutes


Like the Evo set up.

mark, thanks for the advice. obviously cost is a factor in this, which is why i'm a little reluctant to go for the sports cat downpipe. having said that, i can't really be assed to change exhausts at every mot. final question - will simply having a straight through centre pipe but with std downpipe also fail the mot? is it worth doing?

thanks again

Hi m8

could you put me down for a Catted Down Pipe (at 5 price) its for a classic 1998 WRX TypeR JDM fitted - I need to confirm the size of the exhaust thats on at the moment, I think its 3" - if it is I would like 3" connection.

Can H&S wrap it and spray with heat treatment and I will travel from Worcester for fitting.

When can could H&S fit it - sooner than later I will take a day of work if in the week - I have the money ready.

Cheers

Sent you a pm.

Put me down for a Jap stlye back box for a 03 wrx

Ben v7

Removing the centre cat won't cause you any problems come MOT time with the standard downpipe - it will sail through. Is it worth doing? You should gain another few bhp (5ish) and an increase in volume. No need for a remap either.

FLAT ERIC

iTrader: (1)

luke m what he says above m8.

My choice was to either change car & spend a shed load on "cost to change" or keep what I know & play a bit seeing as the warranty runs out in March.Once my plumbing has been done then I will get Pat to Tek 3 & remap it.Not looking for pub figures,just a bit more torque without losing reliability.

Hi

Im interested in a 3" open neck de-catted downpipe for a classic STi5, I already have a 2.5" decat downpipe (dont know make) and from there back the system is a 3" HKS Hiper (resonator middle pipe and backbox), so the system from the downpipe where its mated to the middle pipe goes straight from 2.5" too 3", I measured both just before they join at the flange, there doesnt seem to be any reduction in size on the 3" system etc, so I assume making the whole system 3" will give alot better results.

wrx_rich - what do you mean when you say "to mate to hks hiper without linkpipe"? Is this due to you having the HKS aftermarket exhaust and would I need a linkpipe or not?? Is this what ive read about others buying say an extra 5" section of pipe in 3" diameter for adapting mating to the other system??

Also my car is currently awaiting an engine rebuild so I dont think i'd be making use of the free fitting, unless the saving could be used elsewhere?

Thanks.

WRX_Rich

iTrader: (5)

I don't know but I ve been told

that I don't need the hks hiper coverted ... my car is a new age wrx wit the 4 peice exhaust system

if I use the hks "link pipe" it allows the hks hiper to be bolted to a uk std size downpipe rather than a JDM - This link pipe goes from 3" to 2.5" ( I have it in the garage)

now if i just go streight from the hiper to a longer 3" downpipe with no link pipe I should be fine

but mine is a new age

http://www.brdevelopments.com/hks.html worth a read

if mine dosen't fit I will have to order ther link 3 " flange etc because I wouldn't swap my hiper for no one

Funny you should say that i think we need to put a date on the end of the GB now ;-).

MONDAY NIGHT IS THE LAST DAY TO ADD TO THE LIST.any objections ?????

SO Tuesday morning if you all start ringing up with your payment details and delivery address we can start processing.
CEDIT CARD there will be a 2% charge so if you have then a DEBIT CARD that would be better.

If possible can you ring better 10 and 2 so Dawn can take the details and saves me having to do it.........NIGHTMARE LOOMING :-)

i have amended the list as i needed a downpipe quicker so i managed to source one tonight

Ben v7

Assuming I get my sport's cat downpipe I will also be needing an up-pipe.

I will drive to H&S to take advantage of the free fitting on the sport's cat downpipe. How much extra to pay for fitting of the up-pipe? Any chance of getting it done for free considering you'll be doing the downpipe anyway? Also just want to confirm that H&S are happy to trim the dp heatshield so that it can go back on?

Thanks.

Up & down pipe & centre section for me as well.Spoke to Ian & as I am getting some related work done by my good friends Paul & Knowlesy @ Xtreme it was suggested that they fit it all @ their unit in Boreham.With some adjustment for not getting the free fitting of the down pipe.

I have arranged with Paul for Knowlesy to pick up my bits once I know they are ready as he goes by H&S daily ~ so no p&p.
