RS2 Milltek

[rs2jay]

Just fitted my cat back system and thought I would post a bit of info:

I had read about how far they can stick out so worked with the mechanic to set it perfectly - we ended up taking 40mm off the back of the centre section - you can't mod the front as the centre box then fouls the dif mount. The inner tail pipe now protrudes about 1/2" with respect to the bumper.


Sound wise, a nice deep but unobtrusive noise from idle and throughout the rev range - no booming at any point.

Performance; hard to tell but the turbo does seem to spool up a bit quicker and acceleration at less than full throttle seems better in the 4000rpm area.

Thanks to Pete Reeve for supplying it.

Got any pics of the work that was done to get it to look correct?

[A80Avant]

yes pics would be nice

my rs2 setup was quite boomy for my taste up to 3000rpm,then it became quite quiet!

Not much to show underneath, but I will try and post a picture of the final result at the back. The biggest problem was the rear bracket on the centre box which is bent at 90 degrees so it hits the LH front wishbone mount. There is bags of room for the box to go forward but only if you move/cut/bend this bit. We set it as it came rather than risk damaging the silencer, and cut the end off the outlet pipe instead. The next limiting factor is the position of the hangers for the rear box - with the tips in the right place the rear hanger is only just in the rubber bung.

I'm having a few problems getting the Milltek onto the car the CATS do not want to connect flush with the milltek is there any tricks/tips/hints when bolting the 3 bolts on each pipe together? I was going to use the spacer tubes and springs similar to the OEM set up but only seems to work on a OEM exhaust?

[Smith_S2]

I guess to make this a bit clearer. The exhaust i took off looks to the original one and when i removed it there is 2 bolts missing that hold the bracket onto the diff near the cats, see pic part no 27. The holes do not align up properly and there is a bit of rust inside the holes so it has been like this for sometime, i would like to put the bolts back but i'm really struggling to get the bracket to align up with the holes on the diff i'm using a lot of force trying to align the holes but dont want anything to break on the turbo side of the exhaust and DP?

Thus these bolts missing is causing the exhaust to blow at the join between the CATS and milltek!

Any input would be a great help

cheers

I can't quite picture your issues, but when I fitted my second hand Miltek to my ABY Coupe I loosened off ALL the joints and put everything together finger tight so that I could align it.

I don't know if you have tried this method already, but I found if you start at the back of the car first you won't be able to align the front section of the exhaust with the CATS...

HTH

Cheers,

Steve.

Finally got the system on tonight and not blowing, not as loud as what i was expecting but has a nice burble, i'll try and get a few pics up tomorrow.

[Fat Audi 80]

Well done!

What did you have to do?

[Smith_S2]

A bit of trial and error really just adjusted the tension on the nuts and bolts until it stopped blowing, let it heat up took it for a test drive a little more adjustment whilst bloody hot, added some locking nuts and worked fine, dont know why i got so wound up about it last night. My hands are a bit burnt!.

[Smith_S2]

I also did what you said get the exhaust on just hand tight, worked a treat!!!

[Fat Audi 80]

Glad to hear it...

Looking forward to seeing those alloys after powder coating.
