HI,

I think the best way to make a down pipe to make sure its not in the way of anything,

Is Custom make it out of old or used exhaust, even an exhaust shop can weld it up 4 u.

Unless u can find a very good deal, then go for it! :thumb:

We snailed a D15, and used a small IHI turbo, and the downpipe was hitting the OIL pan, so we just found some old exhausts from junkyard, with the bends we want , and cut and fit it together, then welded it.

GOOD LUCK !

Then put the downpipe there were you have to bend it as less as possible, more bends = bad.
And use stainless steel, weld-turns are available everywhere here in Holland, so I guess they're as well in the US.

Spend some bucks on your exhaust plumbing, it's worth it doing shit right the first time.

- Wed Sep 10, 2008 6:22 pm #69159 When I decided to go boost this was a decision of mine as well. I also found it more economical and had better flow if the compressor housing was facing the drivers side.
After that all I did was take some welding rod to get the correct angles, bought a coulple 3 inch 45* and 90* bends and welded up my D/P. Took maybe 2days at the most, and that includes mounting and adjusting time. To save from buring the oil pan I just got header wrap and wrapped the entire D/P with it.
No worries after that. I can bolt any exhaust with a 3 inch triangle flange to the end of the D/P and call it a day. If you are going to try this, make sure you place some sort of flex pipe in between the exhaust and D/P. This will aid in breaking bolts, welds and other components due to engine vibration. Wleding the flex pipe is a little more involved, but if you are skilled with a welder, or have someone who is skilled its not to difficult.
