What Should I Do With This Down Pipe????
I got this from a forum member but it's not what I had in mind. It's going to take some fabricating. I'm just not sure what to do. It's missing O2 bungs and needs a flange to hook up to the cat. But I think it's to short to reach the cat. If it lines up with the stock DP should I just cut it, put a reducer on it then a flange? Or should I just move on. The only problem with getting a new one is I think the manifold is a custom job so getting one to match up with the wastegate might be tricky. Oh, I should mention that I have no welding equipment (one propane tourch) or experience. Help!

I think of ton of us here have installed DPs that didn't reach the cat and had to drive to muffler shop to get fixed.
Mine cost $75 for them to weld a 1' section, flange, and WB bung to complete the DP.

My solution - BeGI manifold and a GT250R turbo - was to have the muffler shop fab up a compleatly custom system for me in 2.5 inch exaust metal. I got them to make the downpipe a seperate piece with a 'ball and spring' type connection and then (no emissions issues here) a straight run to the back barrel (Dynaflow sports barrel). In the down pipe they installed a bung for the O2 sensor. I then heat wraped part of the downpipe and then painted the whole piece in heat resistant silicone based paint and voilla! One lovely system.
Oh, total cost which includes making the exit from the turbo (flange and design supplied), all weilding and parts, but not the final barrel was $475.00
If I can get the stupid car domain site to allow me to upload some more pics they will be there for your viewing pleasure!

Is the wastegate exhaust to close to the turbine exhaust? I've read in Bell's book about it being bad to have it close and a member also pointed it out to me but for 7-8 psi how big of a deal if it?
