Exhaust questions - 1.8t

[McDub]

I'm looking at a downpipe, and am thinking of perhaps buying a complete system and selling the cat back part of it, basically because i don't want my car to grab too much attention. I would like the exhaust note more audible because all i can hear is intake and engine noise, but i think i'd probably regret it...

Question is, if i get say the full apr 2.5" system and just use the downpipe w/high flow cat (yes i realise you can get the downpipe separetly), do i need to get any hardware to connect it to the stock turbo and stock exhaust (cat back)?

Also, how much would the installation costs be roughly for just a downpipe (with high flow cat)?
And how about installing the whole lot?

And this is probably a stupid question, but is welding required?

Thanks.

Oh and reccomended exhaust shops around lower north shore area, or castle hill area would be good too for when i need to get it done

I have a full 2.5" APR system and although I can't say that it is to loud or to quite (as it is not a unit of measurement!) all I can give is my opinion which is it could be louder! The previous owner of my car put the full system on but took the cat-back off because it was too loud for his wife (it was her car...), but I had it put back on after I purchased the car. Don't expect any gain in noise with just the downpipe, mine was quiet as a mouse until I got the cat-back put back on.

Fitting would cost maybe 2 hours labour (for an off the shelf exhaust system) I think mine took?. No welding required with the APR system, it all bolts together, comes with a turbo to downpipe gasket. If you just get the downpipe then you would need a 2.5" to 2.25"? adapter to fit it to the existing cat back, but the exhaust shop would have these, you shouldn't need to buy it yourself.

most downpipes will mate up to the cat back system, i fitted an ebay 3"(cat less) one a few weeks ago , just used the joiner from the original system.(check my a3 build)

i could help you out with fitting and fab if you want??

Talk to Castle Hill Exhausts - they have a good reputation, and should be able to build something to suit your requirements.

Go and see Chris and Dale from Castle Hill Exhausts. They did all my pipe work. I think my 3" DP plus 100cell cat was $700 installed.

They do smick work to.

As others have said a shop should be able to build something just as good, if not better, for cheaper than an after market product. I found the custom cat-back for my car to be about $500 cheaper than the Remus

thanks for the offers/reccomendations.

i think i'll still get the whole exhaust but just get the downpipe and cat installed.

though is it just me, or does the cat look quite small?

and for some reason, if you select the downpipe on it's own, you seem to get a different one:

ECS ones arent going to be any good. Theyre made for the LHD's. Apparently theres a difference in the downpipe, something to do with where it clears the drive shaft I think. Check out www.awesome-gti.co.uk theyve got a few different types, blue flame exhausts are on pretty big special too atm.

Guys,

As silly as it might sound, I fitted a 'cannon'-type rear muffler to my 3-door GTI(one of the few times my wife has questioned my sanity)......yes it did attract the police on one occassion, but remember in Dubai, the law states "no modifications" (unless you're a local!!) the sound was great, performance no different...but hey it cost about $100 and is probably not much more over here!!

Go for it !!!
