Efi has done this using the IA performance flange and invidia dp's a hand full of times. Works well

It can be had a little cheaper than that if you shop around and get price matched. I paid $450 shipped.

I think that's a reasonable price to pay for a quality made DP that is the proper size and fitment for a setup that is not even OEM (TS turbo + USDM catback).

Mine came with a catted stocker too. Heres the plan though, I have a HKS flat face crap DP(3in ID) laying around and I just finished hacking the JDM stocker(its 2.5in ID). Im no metallurgist, will these two metals weld nicely? If so, Im off to find a competent welder. Pics of the 'hack job'

u can buy a jdm style upper 1 ft of a downpipe off ebay for like 90 dollars. thats what i did. if the elbow is bolted up and the rest of the exh is a shop shoudl be able to get it pretty darn close. we got mine laying under a car on jackstands tacked up in 20 min and it works great. its 3" too. no reason to pay someone 500 dollars for a damn down pipe. waste of money!

So I take it that there's already cheap down pipe options for anyone who has a JDM length exhaust already?

Agreed.

I'm running this thing mated to a 3" USDM downpipe at the flange.

Granted, I bought it used. Someone else did all the hard work!

You could order aftermarket used dp from a importing company. Or order new from any jdm company

Where did you get that sexy DBC manifold to DBW throttle body adapter plate? Is that custom? Whoever designed that must be a genius.





PM me if anyone needs one of these throttle body adapter setups or adapters for USDM rails to JDM manifold.

This. And then this again. It's the easiest and cheapest option and I have no clue why everyone chooses more expensive options and acts like the downpipes are impossible to make/find.

The formula is deal simple!
1) Buy Kinugawa/Tamak twinscroll bellmouth piece on eBay for $100
2) Use old USDM catless aftermarket DP or order an el cheap unit off ebay
3) Take the two to any semi-competent welder/exhaust shop and have the put the two together for $30-50.
4) ????
5) Profit.

Because it is a "hack job" when you cut pipes up and weld them together. We all know that when you buy a nice expensive downpipe it was CNCd from a single pristine block of stainless steel forged billet designed using CAD.

I mean what kind of idiot would pay 200$ for some SS tube and a flange that are just hacked together using a TIG welder operated by a mere mortal. Sure it works the exact same but that's not the point.

I'm sure this has been covered over 9000 times already but this weekend my version 6 207 swap will be done in my gc using the power fc as its ECU. The mechanic won't be able to get it tuned by this weekend and I am in dire need of transportation at this moment. How do I go about getting it to run without worrying about detonation? Or am I just going to have to suck it up,wait, and get a rental?

The casting has real thick walls at the lower end and necks down to below 2.6" inner diameter. So i cut it to the oval section and the circular equivalent diameter of the oval crossection rose to 2.7"

The cheapest ebay downpipe does not have the mounting bracket/ear in the horizontal section. I found that out the hard way. I bought an OEM bracket to weld it there, but my total price grew from around $90 to 110-120 for the downpipe and the bracket with shipping for both.

Most ebay 3" downpipes are 3" outer diameter. The one I got (cheapest), was around 2.7" inner diameter.
The bellmouth was welded into the oval pipe section so I was able to fit the Kinugawa bellmouth after quite some time hammering and busting my knuckles (i felt it was a constatnt reminder about working with stainless).

I don't recall the Kinugawa coming with any gasket, I think I bought a gasket and they don't sell just the one by the turbo, but a kit of two, whichever the second might be.
My rule of thumb is that you can re-use gaskets in the low-pressure section (after the turbo), but only if neither of the two components is replaced (meaning neither the turbo, nor the downpipe in this case).

IAP sells OEM and individual, best quality, but you get one for the price of two.

Now upto 150

Now keep in mind, with each step there is shipping and sometimes even tax.

Now I realized I did not have enough bungs. There is the one in the Kinugawa for the front TS OEM O2 sensor and the one in the ebay at the bottom for the rear O2 sensor.

I bought a S/S bung for my wideband

Now upto 180

I don't have in-house welding and spent quite some time finding someone willing to give a shot welding stainless.

Finally a guy from Midas told me to come in the weekend.

Let's add the Kinugawa bellmouth price at this point

$ 120+ shipping, let's call it $150.

Now upto $330

Now, in preparation for Midas, I had to mock up the misc segments.
I used steel weld, my favorite. 1 tube is around $10, I think.

Now upto $340

Midas did the welding for only $30, huge surprise for me, but left some pores in there, probably to make sure I come back...

Now upto $370

Add some consumables, such as a box of dremel cutting wheels and a set of stainless cuting blades for sawzall, I found that one blade was good for 1.5 cuts, meaning I had to go to the next blade at the second cut. And this had nothing to do with cutting the 2mm thick cast stainless of the Kinugawa, that's where the abrasive discs went.
Roughly $400 ...

At this point, I mocked up everything on my car and ...... It fit !!!!!!

Make no mistake, the 3D orientation of the bellmouth vs the rest of the downpipe is not that easy, I had to go under the car at least 3 times, to get the incline of the downpipe vs the incline of the bellmouth right, so I had every reason to open a bottle of Warsteiner when I saw that it fits..

Then I decided that I wanted to make it into a catalized pipe with a high flow metal substrate, cut the pipe wrong for the converter and shelved the project...

Oh jeez. Sounds like a good experience. Save time, hassle and runarounds and buy something that's quality and known to fit. Unless of course you can do everything on your own with the tools and time.
