downpipes
« on: April 11, 2012, 04:58:28 pm »
Anyone making downpipes for Mk2 anymore, i have a k24 turbo and looking for 2 1/2 - 3 inch downpipe with a flex at the end, i would attempt to make my own but lack the welding skills and tools. Really down feel like running stock. Just let me know.

$170 flux core welder from ebay, + a flange, and pipe of whatever diameter you want. Total cost, ~$225 (assuming you either already have or can borrow a welding hood), but you own a welder at the end. It's what I did for my rabbit  ;D
Or, alternatively, find somebody in the area who'll be your friend and let you use their welder. Beer does wonders.
Stock dp's just suck soooo much.   ::)

I would make you one, but I don't have YOUR mk2 handy for test fitting. At least for me, exhaust systems are kind of in the 'cut to fit' category..

correct ;D ^
Yeah, im in Pa(USA) dont know if someone in pa has the tools to do a downpipe, i was thinking of attempting myself after getting the supplies. Now would i just make something that is similar to stock setup? same-ish layout and bends?
Little off subject but i just clocked my turbo and i am curious if the compressor side is to close to the exhaust manifold or would there be no issue?

I got all my supplies from Colombia river mandrel bending all 2.5" and even the t3 flange.  Whichever flange you get it may have to ground down around the edges. 

i used the following
1 u-pipe
1 - 18 degree bend
3 - 45 degree bends
1 - 90 degree bend
Approx 10 feet of straight pipe

Then remove all your stock pipe and use it to mock up all your cuts and wells away.  I have a bunch of pics at home i can upload later today.  I missed the flex pipe for some reason or another. I knew i needed it but i just got carried away.

an issue you may have with "clocking the turbo is clearance with your intake manifold

where you loacted Trips? i would assume somewhere in the 503 since your referring to columbia river mandrel..
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

Negative, im located in the 604  :) Vancouver, BC Canada

Everything here is way overpriced, also not being able to drive meant that everything I needed had to be shipped.  Colombia river had decent prices and shipping, as well there customer service was very good.

OP, definitely do a test fit with your intake manifold before you torque up up turbo.  When I clocked my turbo for my IC piping I had the grind the intake mani and a/r housing.

As well make sure you use a high quality silicone coupler on your a/r inlet as its pretty darn close to the exhaust mani

do you mean getting the manifold to fit on the head or the piping to go to the compressor? Because i'm foing custom intercooling piping.
And thank you for the info on the piping, the ten feet of straight pipe was for downpipe back right? Pictures arent needed if its a hassel, but would help. Thank you guys, i have decided to do it myself, turns out my wife's uncle runs a rent-a-center and have a welder, so i should be able to do it. Will have to practiace a lot though.  ::)
