what are the best induction/filter and 3" exhaust system to fit to a jdm t/scroll sti 8 please

im struggling to find a t/scroll 3" decat downpipe especially



any feedback welcome

 

K&N panel filter - don't bother with an induction kit.

Miltek sell the ts exhaust systems - Litchfield Imports should have them in stock.

 

spoke to them, they want phone numbers to have work carried out.....way too expensive imho

 

going to be expensive for a twin scroll system

as above miltek or roger clarke

think thats about it

cost my mate £1k recently to de-cat his system with a roger clarke system

 

Few people wanting twinscroll exhausts systems the now - what about a group buy

 

Hayward & Scott make exhausts for Twin scroll cars.

 

What's way too expensive.... the exhaust?

 

I don't know if you are interested in a second hand exhaust system but there is I believe one up for sale at the link below

https://www.scoobynet.com/private-fo...oll-setup.html

I have bought a few bits and pieces from the seller and he is a top man, everything arrived promptly and well packaged.

 

Hayward and Scott, Milltek, RCM and TSL are the main 4 to look at for twin scroll exhausts.
Oh and its not an STI8, its just a JDM twin scroll or MYxx as if you had an STI8 it wouldnt be a twin scroll anyway (if they retained the numbering that is)

If the new Miltek system is too expensive just buy a centre pipe from a classic shape impreza and see if you can pick up a 2nd hand backbox??? The downpipe is already decatted.

 

de cat downpipe around £400 so thats just under £2000 from litchfield for fuel pump, panel filter full milltek and map...thats obscene imho

 

seriously? i didnt know that

ive been quoted £600 for a remap so if filter/pump which is cheap anyway i only need a cat back then? that may help my sums somewhat

 

Ebay, 668 quid inc the backbox, dont know why your after a fuel pump, you wont need one, panel filter, depends what you get, remap at 650quid if you dont already have a mapped ecu for uk fuel, works out about 1300 quid to me.

Tony

 

both places ive spoken to say need fuel pump changing, been offered 2.5" cat back decatted for £250 fujitsubo jap spec secondhand so may do that instead

car is stock at the moment and is fast imho but want 350/350 if possible

 

You dont need to, they do it because its cheap to do, the standard pump will run 360bhp as it has the flow capacity to do so, though "IF" it were me and they said change the fuel pump, i would be looking at a bosch 044 as these seem not to fail like some others do....!

Tony

 

so get the fujitsubo then mr Burns?

 

It will do you for the 350 your after, if your car is stock then you will have to decat the downpipe, check out tsl and hayward and scott for decat pipes.

Tony

 

Is yours also the standard GL/KL (I take it your car is a MY03/04?) or is it a Spec C?

Tony

 

see post #10

 

jdm dec 2002/jan 2003 non spec c

 

If its standard then you will have a cat in the downpipe, its also not recommended to run these (or any new age STI) decatted without a remap as the spike and go pop
You should be ok with a sports cat if you dont go decat (tsl do one on ebay thats quite reasonable ) though they still need remapping anyway.

Tony

 

The GL has the dccd and drivers pack (quick rack steering etc) the KL is the poverty spec that doesnt have the A-DCCD or the quick rack

Tony

 

plan is, get mods fit them then remap the same or following day

so general feedback im getting is decat d.pipe for t/scroll is £400 and thats where i need to decide what to do

 

well that ebay one includes the decat downpipe, centre and backbox for 668 quid, just go on and browse, guy has 100% feedback

Tony

 

Hi i have just fitted a roger clark 3" system including decat downpipe and have up for sale the standard twin scroll downpipe that is 2.5" and the exhaust is a full system fujitsubo right back from the downpipe one piece with two resonators built in which is 3" and bottle necks at the end to 2.5" to mate to a 2.5" downpipe catted or not. its up for £250 for the fujitsubo and i am looking for £100 for the standard twin scroll downpipe and they are rarely up for sale. regards rick 07773279732 ps im in middleton manchester m24

 

he lists for £668, resonated decat front pipe, resonated center section and rear silencer so thats the downpipe included, sounds good

 

I am getting a price for RCM for a twinscroll system as seems one of the best out there - you want to see if I can get a group buy price as few people are wanting twinscroll exhausts

 

How much better are the twin scroll set up's over the single scroll set up's?

Would there be much in it going from a single scroll set up with GT headers and Harvey up pipe to a full twin scroll set up?

 

ordered the 668 deal but got it from Litchfield same price including delivery and all the gaskets, and they say will do me a cheap deal on re-map now

 

RA Dunc........AFAIK the twin scroll has different bends and you have to change the sump as well. Might be wrong though!
