Oh yeah, the flat spot I had at 5k before? I think it was just an FI artifact. It's not there so much anymore.

And the peanut oil treatment: it gave the pipes a nice coloration, but after sitting awhile there is light surface corrosion forming. It's so light you can wipe it off with your finger in places, but not everywhere. Maybe a second oil rubdown is needed.

Surface corrosion of exhaust pipes isn't a big concern of mine anyway; they'll erode from acids on the interior before exterior rust takes any toll in my dry climate, but I know it's a big worry for people in wet and salty environments. It'll be ceramic or powder-coated mild steel or else make them from stainless for the final product.

Just thought I'd share some pics of the system ceramic coated and built up on an engine that is being shipped as soon as I can arrange the customs clearance to Canada (if anyone is familiar with doing this I would sure appreciate your comments. PM me).

Image may have been reduced in size. Click image to view fullscreen.

I made up two copies that were presold, and had the prototype coated as well. The proto is back on my van, sans cat in the short collector configuration.

These are of the long collector version which I do when the system needs to have a cat. It comes with a new universal cat and stainless Magnaflow round muffler:

Doing the copies I altered the design in a few ways, as you'd expect, to make it a bit easier for me to reproduce, and I added actual flanges instead of slip joints where the collector bolts on to the two primary paired pipes, front and rear. Flanges add a lot of cost but slip joints always leak a bit no matter what you do.

I also refined my hanger system so it is versatile enough to be used in either configuration and allows a lot of variance in the actual position of the muffler and cat. I consists of brackets welded to square tube that can be slid along over a square bar to attach to the sleeve clamps that attach adjacent components. It breaks down in pieces so it should be easier to install and position as well:

I added nuts welded to the short square tubes on the two stationary brackets so a short bolt can be tightened against the square bar to keep it from sliding once installed. They're not shown in these pictures.

The goal is still to find a manufacturer who can bend up the tubes, at least, which would hopefully lower the final price of a system, but I've worked out a process where I can faithfully duplicate all the parts by hand and weld them up at home, so they are now officially for sale. Then they get ceramic coated in Santa Fe. The coating is Insulkote inside and out, and a satin aluminum color coat over the outside. The coating is good-looking and amazingly durable.

We did try to fit one up on a 1.9 engine, though, and although it can be put on if you trim one of the fins off the thermostat cover, the cover's outlet pipe is practically touching the #4 runner only a few inches off the head where it would be very hot. The ceramic coating should help a lot with that, but until I take some actual heat readings there I'm not recommending it for 1.9's. Next time I make up some sets I'll see if I can alter that runner to have it come off the port at a different angle to leave some clearance.

That pic with the desert in the background is the finest piece of WBX porn I've ever seen.

Hmmmm, then you'll love these, with my lonely Syncro as a backdrop:

Awesome pics and work! So clean!

I like the setting around too. Rust free environment... I was under my van, and while it is considered as clean, you can still discover new spot of surface rust here and there...

I still have a question for you TC, I was quite surprised by your piping design.

I am pretty sure there are good reason for it, but here is my question.
Why is it so long? It exits to the right, and it also collects to the right. hence a long pipe over the muffler.

Why did you not make it collect on the left side, and just connect it to the muffler?

Interference with mount? Oil filter?

Of the "elbowing" would not work well, either taking to much room or either creating low restriction?

Just curious.

Amazingly clean work otherwise.

beautiful work...
and beautiful surroundings to do all that work! I wish it looked like that outside of my house.

what do your prices look like at this point?

Click on my ad URL in my sig line. Prices are near the bottom of my ad.

So far, the system is only going to fit 2WD that have the 2.1 cooling system. Don't have the front runner to clear the skid bars for Syncros yet. Those other versions will be forthcoming, when I have time to work up the changes. Only so many hours in a week.

Crughy, if you review this thread I did some explanation of the reasons the pipes need to be a certain length. The long 2.25" collector pipe that goes across above the muffler is the optimal total length for the collector on a full-wave tune, nearly equal to the total length of primaries and secondary combined (a few percent less to compensate for the gases cooling and moving slower by that point). The Magnaflow is a straight-thru round design, which would be very loud if used with no cat, but the cat quiets it some to keep the noise volume reasonable. Only a round muffler will fit well in the remaining space.

Due to limited muffler selections (can't find a 5" round performance chambered muffler for a reasonable cost), I do a half-length collector for non-cat versions that results in the muffler being mounted center-left and the tailpipe exiting the left side of the van instead. That way there's room to use a chambered oval muffler, which is needed without a cat to have a nice sound that isn't obnoxious.

It's all the result of a mind-warping complexity of balancing one need against another against some restriction against some other need. Maintaining ground clearance is high on the list. If that didn't matter, the system would look very different than it does. At a glance there appears to be a huge space up in the muff attic, but try stuffing a bunch of pipes in there and see how little there really is!

Thanks TC.

I read it as it was going on. I did not remember all the details, especially the sound ones.
I know it's not an easy task. clearing all the parts, clearance.

It's nice looking. looks well balanced too: like a "natural" OEM well thought system.

Please make versions for the 1.9.

PLEASE?

There's the syncro! weird that you'd show it just hours after I was asking about it. Wow it is beautiful there, nicer than NYC thats for damn sure.

Please make a header for the Tiico. The crappy one from Mieneke (PO's choice, not mine) on my van is cracked again. I gotta buy me a welder.
