I know this has probably been covered, but I want to make sure. Bringing my 93 golf 1.9 td into the muffler shop tomorrow, will catback 2.25" piping (non-mandel bent) be enough? or should I go 2.5"? I don't want it to rattle either, also putting in all new hangers to make sure. car is lowered on h&r cup kit.
thx guys.

I have 2.25
I have H&R Sport Springs
No problem
PS: you will not see any improvement with the bigger pipes unless you change the tiny stock turbo.

well the boost will be upped, not sure where etc, that's for my mechanic to decide. stock I'm peaking at 14psi and doing 11psi sustained how large is the stock piping?

Have you considered making a mandrel bent exhaust? Any decent exhaust guy can make it using mandrel U-bends. I plan on doing 2.5" on my 1.6TD. We ran all of the airflow requirements and with boost around 20 psi it was moving about as much air at 4500 as a 16v (I don't remember if it was a 1.8 or a 2L) would at 7500. You'd expect to run 2.25" on either of those engines so I would expect thats all the 1.6TD really needs (therefore I must do MORE than it needs). So, being as though the exhaust is going to be crush bent and you're probably referring to a 1.9 I would recommend ATLEAST 2.5".

I think the stock pipes are 2"
but its the turbo that chock's off the air flow.
The exhaust gases have to push true a 1" opening when going true the turbo

A turbo from a 1.6TD would be a nice upgrade (then the 2.5" piping would be worth it)

that is probabyl what I will end up doing. thx, if the shop can fit 2.5 without rattling, i'll do it.

the 1.6TD came with two difference turbo's
the better one if you have a choice is the KKK K24
which is slightly bigger then the Garrett one but both are a great upgrade to the puny stock turbo
(get the manifold it bolts right up)

I am runing a 2.25"-2.5" Downpipe it converts after the first bend, into a 3" exhaust with a dynomax race "bullet" muffler and out. It is all mandrel bent no rattling. I would recomend as big of an exhuast as you can get 3" is a bit of a pain but on the other hand I can't get my egt's over 1200 pre turbo, no matter what I do, And my garrett turbo will hit 20psi in first gear. somthing to think about anyway. That and the out put of the holset I am going to twin it with is 3" so I will be all 3" in the near future. :twisted:

got 2.5" non mandel bent, fits fine, i heard a clunk once or twice, but no anoying rattles so far. Instead of the power dieing off near the top of the gears, it pulls the same to fuel cutoff, feels like a good improvment, little deeper than it was before, not unbearable or loud inside the car. paid $150 canadian total.

That seems like a fair price.
Did they give you a quote for mandrel bend?

nope, figured it wasn't worth it, i can't see any restrictions with the current setup.

for those who are wondering, last night my car was stolen, had the exhaust done on friday, cop said it didn't look like the locks or ignition were damaged. ONyl peopel who have had access to the keys is the muffler shop i went to.
-------------------------------------------------------------------------------
Someone called it in as a suspicious car this morning, was parked in a residential neighborhood in front of a house, the turds put the club back on the steering wheel that they cut in half. Yay, faux security.
Spoke with the officer that was there when they towed it, they put it up on dollys, said the door locks and ignition looked unscathed. No visible damage, everything there. Front door handles with no locks will be going on when I get it back, as well as a high end pager alarm, professionally installed.
So either someone got a copy of my key, or they are very good lockpicks. I'll see the car tomorrow, after they fingerprint it, the morons left their hacksaw in the backseat. (oh how i'd love to use their own hacksaw to cut off their theiving fingers )
