Ahh, I see... Still annoying that they shoy they are more than capable of pushing 170hp out of a 2lt lump yet they de-tune the Fez to meet insurance demands

Crispy is correct on alot of those facts. unfortunately crispy the ST170 engine is quite different from the one in the fiesta. the ST170 engine had VIS and also has VCT which where used to create the 170 hp, in the ST170 if you do the full exhaust and intake + tune and a tunable exhaust timing cog and Under drive pulley youll see the 200hp area easily and this has been proven... so unfortunately the XR4 engine is actually a 2.0 Duratec alloy enigine where as the Focus St170 has a cast iron block with an aluminium head. its the sam cast iron block used in the original escorts i do believe from what the mk2 escort club tells me.

REALLY!! the old pinto block still getting around

so can this vct head be bolted onto a duratec??

i happend to be looking into a milltek flexi and i saw the bestmufflers site and wasnt to sure but seeing people are happy i have booked in for saturday.
it saves waiting for it to arrive and the aussie dollar is a killer.
once i get this ill book it in for a custom tune to get her running right.

Hi guys,

Sorry to add to an old post - I've decided it's time to bite the bullet and get myself a decent exhaust system for the Fez. Can anybody recommend an exhaust shop in Brisbane?

BTW, the Fiesta just had its first motorsport experience on the weekend - a tarmac rally/motorkhana/navigation rally sort of thing. Think it went pretty well, but no results posted yet unfortunately (damn this thing does well through chicanes!). Will post an update when I get results and pics.

sent you a PM mate

im also from brisbane should go for a cruise sometime man

i have a silver xr4 no stripes.


id buy exhaust from overseas and get it shipped

go to A1 exhausts to get it installed.

A1 are great.

i have a milltek flex pipe and eibachs on mine.

looking at getting remus muffler from best mufflers.

and might get K and N 57i filter.

eibachs have given me bad camber so tyres wearing out fast.



are you also on fordxr4.com ??

I have a full millitek system ( curently have the cat in place)

Not sure that you will get huge HP increases, and it is a bit quiet.

I am actually thinking of selling the back millitek muffler if anyone is interested.

Anyone try a set of Mazda 3 extractors????????????????
Duratech engines in both cars. And looking at the engine bay of mum's Mazda3 and the GF's XR4, I think they may just fit.

Anyone tried it yet?

Wouldnt be much point, the mazda makes less kw's than the fez.

The Mazda ones would still only be tuned for economy/cost.

Perhaps, but I am sure some tuning company would have made extractors for a Mazda3... So in theory it should fit an XR4?
Pure numbers of cars sold would suggest there would be some decent aftermarket support. Could be wrong though.

But there are plenty of options for the XR4/ST150 already...

Piper
Milltek ( 4-1 and 4-2-1 still available some places)
SWA (South African - very well priced and two piece for easier fitting)

I think there are also ones by Blueflame, Inox, Simpson, and a fair few others...

Plenty of support in the UK so why not buy something you know will fit and perform rather than worry if sensor locations and bolt patterns are compatible let alone the shape needing to match up with the rest of the exhaust and clear everything in the engine bay. Doesnt make much sense imo

I would just buy the millitek headers and flex, and get the rest custom made.
Save on freight. Plus you can decide how loud/quiet you want the rest to be.

Don't think fitting the headers is that easy. You have to undo the engine from its mounts, tillt it forward etc etc to fit it in. I had my mechainc fit mine and it was all pretty tight going.

was thinking of buying a mongoose exhaust kit with the flex. but just got my outside calipers and did an eternal pipe measurement from stock. i dont think doing the mongoose system is worth it, the mongoose is 2inch, and the external for stock is 2.16". i think it said on milltek that their pipe was 2.36", i think.

is it really worth replacing the whole catback? or should i just buy 4-1 headders and straight through muffler and de resonated? XD

Go to a decent exhaust shop and see what they think.
But from what people have been saying on here, the standard system is fine apart from the flexi and muffler. So if you were to get decent set of headers w/flexi and a good muffler you should be right.

mmmm yeh, that sounds the go. i like the sound with headders and no hotdogg, as i like to call em....

im also woried about drone in the cabin. :s my biggest fear. but exhaust dude said it shouldnt but if it does, we will put the old back on. just need an rdo to come up when i can book in

I am very keen to get the backbox replaced with something Staineless Steel - XForce or Magnaflow from Best Mufflers. I already have the Stainless Flexi + K&N Apollo CAI, so i think a new exhaust will complement it. I understand a few peeps have changed theres so just after some advice.

Would you recommend replacing the cat with a high flow one? 2.5inch both sides??

Is the existing piping 2.25 or 2.5 inch??

Would it be too loud if i removed all resonators, regardless of what muffler I have?

i just want something that is a bit louder than stock, nice crakles and pops when backing off...

Any advice will be great.

Id just change the muff, keep the resonators, other wise it will be ridiculously loud inside the cabin. Best mufflers (like other good zorst shops) will tell you the current system is fine apart from the flexi and rear box, its stainless and 2.25 inch, going to 2.5 will only make it go at high rmp, your low end power/torque will probably drop a little.

IMO

Went and saw some exhaust shops today.
Requirements were - 100% stainless, flanged, not a cannon, no drone and not loud. I want it to bring out the exhaust note without the whole neighbourhood hearing me leave. My main aim is something free flowing.

First stop was Exhaust Technology. He was pushing the JunBL muffler pretty hard, had a look at it and not overly impressed. It reduces in pipe size considerably inside the box. $640 fitted :S
Also offered a cannon and not once looked under the car. Grrrr.

Next went to AAA Exhausts. Was greeted by Jim, top bloke. He got me to put the XR4 straight up on a hoist and had a good look underneath. Spoke about what he proposed to do and how it would sound. I got the feeling he knew what I wanted.
Jim suggested the Genie stainless straight through muffler fitted at $460 and as we talked more he had a rethink and suggested I might prefer the sound of the Magnaflow box at $520 fitted. Both mufflers are a quality item, the Magnaflow being better presented with the polished look where as the Genie is a brushed stainless finish.

Then stopped at D&T Salisbury. Bloke there poked his head under the car. Had a quick chat and suggested a Supercat reverse flow muffler fitted at $450-500.
Not overly keen on a reverse flow muffler. They don't give as good a note in my experience.

Think I will stop in at Everlast too when I have a chance, but am definately leaning towards AAA. I've had them recommended to me by numerous people and was impressed today.

keep me informed on which place gives you the best price fairmont1998 as i'm looking at getting a new rear muffler for mine but i only went to exhaust tech and yeah don't really get much of a choice there its either lukey or jun bl

He bagged Magnaflow too, lied about them being mild steel internally, when they are 100% stainless.
Not interested in people who instead of talking up their product, resort to bagging the opposition.

yeah personally i think exhaust tech have gone downhill the last few years...people will say anything to sell there product

Booked in with AAA to be done in a fortnight

cool...wat sort price did they give you? love to hear it when you get it done

He said on the phone he is confident he'll beat the quote he gave me. I'll post up the price once its done and will get some vids of how it sounds.

Had the rear box done today
Took half a day and its fitted with flanges, as well as the original so I can swap them at home if I need/want to. All up cost $460 which was lower than the quote Jim gave me.

Jim's workmanship is supurb, everything is done in stainless and the new tip (I supplied) sits perfectly in the bumper cutout.
Has a nice very deep note, will get some clips as soon as I can.
