I can't seem to find a source for a b4 downpipe, a new one that is. Steel or stainless, doesn't matter. Anyone know of a fabricator who has the pattern ? Thanks.
Downpipe source ?

Downpipe (B4)(A3)
This downpipe, made by K&B Fabrication, the same maker as our A4 downpipes, is designed to improve on the flow and durability of the stock VW pipe on B4 and A3 chassis cars. Each pipe is made o...

Unfortunately, K&B hasn't provided a downpipe in a while, and ID parts says they have been on backorder for a long time.

- 98 Jetta TDI AHU 1.9L (944 TDI swap in progress) I moved so now i got nothing but an AHU in a garage on a pallet.
Imo go to a proper exhaust shop. Aluminized steel pipe. Take it to a ceramic coat company.
60% less than SS job and lasts as long. You can diy the ceramic with cheap bbq paint. Just do not wrap it.

Thanks for the suggestion. We need a cat here in Virginia, so I opted to purchased this one: https://tinyurl.com/4bh7nr3s

Lucky you. Communist state of NY is requiring inspection stations to upgrade their inspection computer stations to ones that have cameras that can see vehicle being inspected, supposed to be in by end of year, according to station I use for inspections....

That'll work on the B4 wagon? Hopefully the bends are same for the B4 compared to the MK3 Golfs/Jettas....After some fairly extensive searching, I bought this one but have not yet installed it.

I had a good conversation with DarkSide, and they were certain it was an exact fit. As I haven't yet installed the pipe, I don't really know just yet.

Weird. I must have bought the last one IDParts had, because I bought mine in late November and it came basically right away.

I received the downpipe I ordered from Premier_performance. Before someone else finds this thread let me announce to all, do NOT consider this pipe as anything other than a laughable excuse of cobbled together pieces and parts. The mig welding is so atrocious I wonder how long it will be before the joints rust or break apart. Mig weld splatter wasn't cleaned. The first joint after the turbo flange connection has a 1/2" piece of the subsequent pipe sticking up into the air flow, which must have horrendous effects on flow. It has arms welded to attach to the non-existent rubber isolation snubbers never found on a b4. All in all, this downpipe is just unimaginably poorly constructed and assembled. Save yourself the time it will take to return it. Pics are available. In plain language, this product is just tooefed.

We can get these made, we just don't stock them anymore because of low sales volume.
And the only difference between the B4 and A3 pipes are that the B4 has an additional hangar, which we don't include on the pipe, so it fits both cars.

The part numbers you provided didn't have pictures. I emailed the seller who did not provide the information necessary to get a warm and fuzzy feeling to buy their product. One of the numbers you provided was dead.

737-261 does not appear to be close to a 96 b4 with 1z/ahu engine. DEC VW3426 The seller stopped communicating with me after I asked for more details and a picture. Thanks for you help though.

I think you have that backwards. Odd decision that VW didn’t include the hanger on the more expensive German car, but included it on the lower cost MX Jetta.

I believe my B4 was assembled in Belgium.

My mistake there, but it still doesn’t change the fact the B4 had no type of dp support. The first hanger on the B4 is after the tunnel, leaving everything forward to hang off the turbo. The Jetta TDI got a support, at the beginning of the tunnel, mounted to the steering rack.
I’d imagine this lack of support is why many B4s had the flex joints fail and why it’s not an issue on the A3s.
