Going turbo soon and I'm talking to a member on here about buying his treadstone dp and manifold setup. If he ends up selling it to someone else, I will have to make my own. Even if I DO get my hands on his I still want to see what other people are running.

So post up pics of your downpipes, on or off the car, and give some details. Where'd you buy it, or what material is it made out of (if you did it yourself). Does it hit the AC compressor? Does it replace the cat or bolt up to it? Any type of helpful info that you can give would be appreciated. But a picture is worth a thousand words.

3 inch piping, 14gauge mild steel. However, I will switching this downpipe within the next couple of weeks. I will be fabrication a new downpipe from stainless steel, relocating the dump tube into the pipe to another location, and welding on a 3" vband onto the turbine itself instead of using the 5 bolt flange. I will also be welding on a -16AN male fittings onto the thermostat housing and into the radiator to use a braided hose to with stand heat better then the new OBX hoses I have on it, and also will be elimnating the heater hose pipe and heater hoses since this car is no longer a daily driver...

I wish I didn't. IMO, the extra weight doesn't offset the gain in temps. I gained right around 10* when I pulled the heater core on the NA. AND, of course, I threw it out, lol.

I know it will raise temps, however, I always have some thing up my sleeve to fix that issue

hard to see, but it is an ATP turbo 3" v-band. I love it, and i dont think they make it anymore.

98rs eclipse- Mods: BC2, C/F hood, custom turbo system consisting of a PTE SC50, turbosmart ultra gate (10psi), star FMIC and pipes, SFMU, HKS SSQV, 3" V-BAND downpipe from ATP, Zeitronix Wideband LCD displaying boost, egt and 02. *** SOLD and will be missed***

2006 gsxr 750- jardine gp1 exhaust, -1,+2 stealth sprockets, DID 525 chain, JD products pro TRE. 0-60 in a sneeze. ran a 10.8 avg 1/4 mile my first time to the track on street tires, stock swingarm and unstrapped.

3" SS v-band from turbine housing. 3" OD, 0.065" wall SS mandrel bends and pipe. I give the exhaust gas as much straight pipe as I can before the turn (trying not to hurt spool-up). From there, it sweeps down under the manifold. Wastegate dump follows, going under the manifold. Everything is wrapped, to keep heat where it should be.




The downpipe is split with another v-band. That angle is actually not cheated. It is welded to a thin slice of mandrel bend (from before I had this joint). The wastegate dump merges in at a low angle (to minimize disruption of main exhaust flow). I've got bungs for the stock front O2 and wide-band O2. A bracket bolts to the block. A short flex-joint, a couple bends and we exit at another 3" v-band (the remaining exhaust continues with 3" OD, 0.065" wall SS pipe and v-band joints all the way to the muffler tip).




The pipe is wrapped to keep heat out of the oil pan and keep the cat hot. I put a SS skid plate to keep from tearing up the wrap and flex-joint on the lovely VA roads. I did all the work myself. Many, many hours were spent cutting, fitting, and TIG'ing it together.

Corbin, that's an awesome setup. Very impressive. I was looking for more typical setups but got more than I bargained for. Did you weld the manifold yourself, too? I need a lot more experience with welding to get to that point but I do have access to a MIG & TIG machine as well as a plasma cutter. Hmm, maybe one day

grrrrrrrr corbin

You call that a downpipe? Ha, now this is a downpipe, lol.



J/k about the Dundee line. I just like to use that line. Here's another pic of the business end;



That would be 3" straight back (all the way to the axle, at least). my own design and fabrication (tack welds only. I can't weld, lol)

That is what I call a pipe.

Haha, thats great

Ordered my IC, IC piping, wastegate, bov flange (maybe I'll TIG that myself), MBC (Hallman pro, woohoo!) and all the gaskets I'll need yesterday. One step closer.. Just need oil lines, bov, boost gauge, and a few miscellaneous fittings and of course the manifold and dp from the 2gnt member and I'm good to go. Look for an install thread soon

I started with the POS Hahn Downpipe...which is basically just the top portion that fits over a stock DP. Since the stock DP is crap as well, I decided to craft my own for my s16g application.

I used the basic Hahn 2-1/4" piece with the 16g flange connected to a 2.5", 90 degree elbow piping and a flex section. Then used 2) 45 degree sections to make the upward curve. Matched the flange to the Cat delete pipe, drilled and welded on the 2) o2 bungs (one stock, one for the WB A/F gauge) then had it Jet Coated with their 1500 degree coating. Done.

Here are a few pics of it off the car.









Here it is coming under the car once it was installed...you can see the factory o2 placement.
