    Think that definatly justifys a rediculous exhaust as that cars mental!

    Can't believe that they rev over 10k as didn't think it would take it

    That side exit is mental but think it would be a tad to loud ;)

    I can see anything bigger than 3" fitting past the propshaft on the S3, its bound to rub or knock somewhere in that area.

    Got to admit I've never heard of anything bigger than 3" on an S3 but also not sure if it has been tried?

    I expect it would be a challenge if even possible to get anything bigger past the prop?

    its got to be impossible. there is about 10mm room all way around a 3 inch. it would never work without touching with engine movement.

    Exhaust Resonator De-Cat Silencer Universal 3.0" Turbo | eBay

    Like that. A lot of Jap systems have those.

    Could have that in the standard center box location and a proper box where the standard cat would be. Didnt think of it looking like a cat so thats a cheeky plus lol.

    It may need some strategic dents placed :laugh:

    But saying that my H&S downpipe had dents and flat spots all over it in the end to stop that rubbing and that was only 3"

    Cheers mate think it will need a good couple of boxes/resonators like you say to quieten it down, but suspect on boost it should still sound pretty good

    Suppose an ideal solution is an exhaust valve and then can have best of both worlds but that's just a pain in the arse

    Aye easier just to stick a few boxes in it. I think with a front box in place of the standard cat, resonator in the middle and a backbox it'd be alright. I remember a similar subject on driftworks years ago and soneone said they knew of 500bhp+ cars that sounded almost standard because they'd run loads of boxes and it never really effected performance either. Only one way to find out though and that's to get it build, let it soot up and see what it's like. If its too loud change a box. Also different packing in the boxes can make a difference so could be worth looking at which does what.

    Will when i get some free time ring around for some quotes with a cat back with a ****e load of boxes lol

    Little update although nothing major, mainly just been connecting lots of stuff up

    My rear springs have eventually shown up as one of mines currently in 2 :faint: wasn't impressed with the state of the package from the couriers

    [​IMG]

    Mocked up what the tip should end up something like

    [​IMG]

    A pic that gives you an idea of the size of the pipe, Mila's got a thing with sticking her tongue out at the mo lol

    [​IMG]

    Couple of pics of where its up to at the mo, pretty much everything is connected now with just the charge pipe to do

    [​IMG]

    [​IMG]

    The coolant hardpipe that had previously forgot to take pics of

    [​IMG]

    Coolant lines which were an arse to get round the tip

    [​IMG]

    Pretty much all got left engine bay wise is charge pipework, tip and fuel lines

    I have decided for now to run just the 044 inline and see how it goes? It may well be a nice future project

    Looks awesome dude !! Great work.

    Is that a hemi TB on the IE mani? Does the TB harness reach the TB plug, or do you have to extend the wires?

    Cheers mate :)

    Yeah 80mm hemi tb and the harness just reaches but may extend a touch if feel its under to much tension and may have to rotate it yet for better clearance to the bonnet

    Iirc you've got the same tb? If so how did you find the connector as states on IE's website that it may need minor modification but doesn't say in what manor? The plug goes on half way but didn't want to be to forceful with it...will have to look at it in a bit more depth on Monday

    TBH I cant remember modifying the plug when I fitted the TB, it was a tight fit and needed a good push for it to click. I would have a look at it first if I were you, because I had 2 hemi TB's. One was made in Canada and the other in Germany. Canada one didnt work so bought a German one. They were slightly different in some areas but were both made for the same car.

    It's a compact housing he has so I guess 3"? Unless that 90 bend has 3" one end, 4" the other?

    Lol tip is 3' to 4' 90 silicon and 4' there on, the maf is a rs4 unit with a 90mm OD but have machined a plastic sleeve to press on to it to bring it up to 4'

    [​IMG]

    Pic of the part no

    [​IMG]

    The billet velocity stack then takes the size up to 6' and will be looking to get the biggest filter can get in between the stack and the headlight ;)

    [​IMG]

    This is the filter I originally got when still had the battery but now have got some room over that side will be trying to get near enough the biggest one I can fit in there ;)

    [​IMG]

    I also fired off an email to IE and they said there's a little tab that I need to shave off on the tb plug then shall fit nicely :)

    Mine is 3inch inlet aswell. I want to run a 90mm tip with 4.2s4 maf housing which is what i was looking at. If i can find an rs4 one then thats even better. The s4 one i believe is 87mm o.d. 90 would be better obv.
    Where did you get the maf housing stace?

    After some suggestions for exhaust places guys? Have got quotes from blueflame and pipewerx but are miles and miles away from me


    Have also tried Jetex who said don't do custom and piper exhausts said the same but am waiting on a phone call back about possibly making a 3' system as an off the shelf option like Jase had previously been discussing?


    Anyone reconmend any other reputable people preferably in the south east area?


    There's always the likes of powerflow lol

    I might be in touch about that filter then. Does it need a velocity stack?

    Know any good welders around your way? Just buy the bits and get it welded up by them. Dunno about companies around your way. Everywhere is miles away like you say.

    Few meters of 3" pipe on ebay isnt much, just be the boxes that`ll make up the cost. Im going to be buying some pipe and a backbox from ebay after holiday and fingers crossed me and Jon are going to make one similar to the one he`s just built himself which is really good quallity. His is 2.75" catback but im going 2.5" and building it from the center box back. Main bit i want to get rid of is that nasty squashed section under the diff and the heavy backbox.

    He`s got an MIJ japcan like i had on the A4 and im going the same route again as i love S3`s with nice cans out the back like all the greek 0-400 cars and unitronic beasts. Comes with bung that i`ll use if needed for track days and its only 38quid or something. Going to cost me about 80quidish for a 90 and 45 bend, 1m straight 2.5" and the backbox

    He might still have a race cat. It screams more "look at me my cars modified", which is why I like the Milltek. Reasonably OEM looking rather than ricer.
