ATS 3-piece manifold

[RADdodge]

They do look good, but I’m starting to see some rust come out on mine. I had it Jet-Hot coated. I called them up and they suggested using Mothers or some type of paste metal polish. I haven’t tried that yet. Maybe this weekend. If it doesn’t come out, they guaranteed another coating, but I hate to have the truck down waiting on that! I had the bosses coated too. It was a tight fit. I had to heat the center manifold up to about 500+ degrees to fit the pieces together. Here’s a picture of the finished results. There are a few more pictures of it in the "Truck Pictures" below.

P. s. I would strongly suggest drilling and tapping the pyro sensor hole before getting it coated. I also lightly polished the casting to sooth it out before having it coated.



P. p. s. You will also have to modify the heater hose support bracket.

Anybody had theirs port/polished? Joe says there can be a 15% increase in flow in one of the recent TDR mags. Just wondering.

Does drilling and tapping for a pyro tend to chip the coating?

Should it be drilled and tapped before coating?

I had no problem with the Jet-Hot 2000 when mine was drilled. No deterioration on the coating either. I have the flat black coating and it stains easy with silver antisieze thread coating.



PS, gotto get my gripe in. I just had the front section off this weekend for the upteenth time trying a different sealant for the bell. The stainless shim stock I hammered into shape had held up the best.

I contacted Rob at NWBombers as he recently installed an ATS, but only applied high temp stove paint before installation. He replied the same paint lasted on his stock manifold for 3&frac12; years and another NBombers' ceramic coated manifold rusted in less than a year.



This is the very reason I detest chrome plating. Once the base metal oxidizes, you're screwed.

Thanks for the feedback, I will use a stove paint. <blockquote> <em>&quot;...

Don't they use a vertical lap style compression ring seal to prevent exhaust leaks?

I can remember reading about the "bell" fittings in a review. About how they should be snug perhaps requiring tapping with a rubber mallet, etc. I have one that is sloppy. I thought it would snug up a little over time as I have seen three piece manifolds on larger diesels do. Over time, whatever I put in the joint breaks down and the soot starts blowing. I know of at least one other person who had the same problem.



Part of this is my fault. The manifold sat when I recieved it, was sent for coating, sat some more until I had time to install it. I had never tested the fit. The reason I gripe though is I had contacted the company but got no reply. I also want to make others aware and to test the fit.
