Cracked SS Tubular Mani. DSM

So, I have 1G DSM with a SS tubular exhaust manifold that was sold to me as a DNP. It doesnt have the DNP plate on it but its also 7 years old. I noticed its leaking at the welds to the flange to the head on 2 of the cylinders. The thing is this car gets VERY FEW miles put on it, 200 a year, and its a stock turbo housing so theres not a bunch of weight hanging there.

Is this fixable? Just weld more over top of whats there? Who could do a good job? I don't want it looking like crap.

Has anyone ever seen this before on a $600 manifold?

the last 2 pics are to help determine if its a real DNP. I know the plate isnt there but all the reinforcments are there under the cylinder tubes and where they collect.

 

DNP's warranty is 1 year. so either way i'm screwed.

Im still gonna say ebay,cause even is the logo fell off you'd see where the tack welds were plus i've never seen a dnp discolor that much,And look at the welds on a real dnp (#1 runner to be exact)theres 2 seams as where yours only had 1 seam.

I have the manifold off the car now. Can't seem to get ahold of anyone to weld it for me. Heading that way next weekend. Help please!

 

We can fix it for you no problem (If you still are looking for someone). Call or email the shop anytime :)

looks like they used the wrong filler rod to me. they welded cheep 304 stainless to mild steel. turbo headers should be made from 321 stainless to reduce the chance of cracking. i could weld it for you but i don't have any of the filler rod you need at the shop or the house.

Exactly what I was going to say...
