Ok, so Stans, and Sourceautomotive have 4" Downpipes right? Which downpipe is better, and if it is stans, which one should I buy? I have an hx-35, with a similar flange to the h1-c.

even though sourceautomotive's downpipe is about $210, it does have a 3" v-band flange and they have a good rep throughout these forums. if it were me, i'd buy from them.

i bought mine from scource and the quality is top notch. I couldnt be any happier

The only reason source has their down pipe with a flange is because stans came out with their's all welded with a flange. I got mine from source before this so I had to weld my own flange on there.

If you ever think you might upgrade turbos you ought to get the DP with the 4" hx-40 type flange.

I got Stan's a year or so ago, top quality work, couldn't complain, could only recommend!

I have a source auto, could`nt be happier (well, mebbe a 4in outlet turbo to go in front it perhaps).

Yours came with the heat sheild? Mine was $190 from Source plus almost $60 shipping . Very nice though, and my adaptor was welded on. SHould have gotten the 4" though since I now have the HE351cw to put on. They want over $50 for the adaptor, but the local diesel shop had a fleetgaurd one under an International parts number that was under $11. The same Cummins one was about $30.

Home made is cheaper and just as good. Bad pic, sorry. Just sold the truck today, so can't take any better pics.

Do you have a part number?

So The Stans HX-40 Downpipe has a 4" flange, and I can buy an adaptor to go from 4" to 3"? Is that correct? Will I still have clearance between the turbo and the firewall? (hx-35 sits about an inch farther back than the h1-c.)

Thanks guys! Good Info!!!

i don't know if you could buy a flange from them, but wherever you get it, you'd need 2 v-band clamps. i'd say buy the downpipe for the h1c for now. when the time comes for an hx40 or any other turbo with a 4" outlet, cut off the 3" flange from the downpipe and have this welded onto it...

Flared Flange for 4" Exhaust

That isn't the right one for the HX-40 style.

you need this one:

my apologies. i have see that one there before. i was in "nascar mode" and just went under the exhaust flanges and found the first 4".

Bottom line is you cant go wrong with rip. He offers them with the hx-40 flange and the hx-35.

Ok guys thanks for the info. The stans or the source auto pipes will both clear the firewall on my hx-35 right? Is there one that clears better? Thanks again guys!
