Tri Z Engine Build

[El Camexican]

It never occurred to me that it may have been welded with a gas torch. On a second glance it probably was. I should be able to tell for sure when I look inside the pipe. The reason I assumed it was tig'd is the little pin holes that appear in a few spots (I'm not saying they are through holes) These happen a fair bit when TIG welding mild steel unless you're purging the inside of the pipe. The cause is heated impure air trying to escape as you complete the ring. If you purge the pipe then its full of argon and the weld looks a lot better on the back side as well. I haven't gas welded mild steel with anything but bronze for years, but I don't recall having pin holes like that.

Anyway, I want it made clear that I am NOT complaining about the pipe, or the welds (as long as they don't leak), I'm just showing ya'll what I received. You can be your own judges as to what you would pay for something like this, all I'm really concerned with is how the trike runs.

For the record my last DG pipe came with a pretty large pin hole in it that leaks pretty good. Nobody's perfect.

I looked, it's gas torch welded.

I was just looking at vintage pipes on line to check out the welds [yes I'm weird] and came across this . . look at how many sections it has . . it looks like an ancoonda has a carbon fiber silencer too . . must have cost a bundle.

Wow, I am shocked.

I have seen a few Jemco's and I don't remember them looking like that, I would give them a call and also check with Mike (Oscar Mayer on the boards) he had a pipe built for his son's race quad and said it was great looking.

Those pipes and many others are gas welded, but they are "flowed" meaning no filler rod is used.

If you keep it just MIG the brackets, years ago brackets were gas welded or brazed. Bill's Pipes were the first to MIG weld brackets and got some flack for it many years ago, now it's the norm.

You can just blow that dent out pretty easy, I hope it happened in shipping.

As for the extra spring bracket, I alway run two springs per mount with a piece of real rubber tubing a 1/2" long located dead center it keeps the springs from rubbing and vibrating and adds tension too.

My Jemco pipe has an large collar too, I guess that's the way they make them. How much did it cost to have a new pipe made? Did you have an option to buy a silencer from Jemco? My DG pipe fit so tight I had to sand the exhaust spigot a bit to make it fit.

An absolutely beautiful specimen! It looks like the work of Jollymoto.

I have sold many of those exhaust gaskets in the last 6 months but have had to put them on hold for a bit as my work where I make them has been really slow and laid me off job attached. Dont worry they are not gone forever just temporarily until I get a lathe at home

Uff. I was hoping this wouldn't turn into a pipe bashing thread (no pun intended) I recall the packaging was a bunch of cardboard sheet wrapped around the pipe with tape, but it was a month ago and I received a bunch of other things at the same time, so I don't recall the packaging exactly. The pipe went straight into the cab of my truck after that.

The one weld I can see from the inside shows part of the collar staggered from its mate and from the outside you can see that a few of them are offset to each other by well over 1/16", but less than 1/8". The gorgeous welds in the photo Barnett posted (by the way I did see that one before, so you're not the only weird one on here) are the way the welds appear on this pipe on the lengths of the cones, but not on the circumferences. As I look closer there was filler rod used on all of them.

That all said the pipe was $404.58 including shipping and paypal fees, so let's step back for a minute and remember that we get what we pay for. This was not a $900 custom job. Ask Billy what his pipe would have cost had he charged himself minimum wage and materials

On F1: I picked up a cheap little TIG/Stick machine the other day, so MIG, Stick, Oxy Acetylene are all options now

3WD: I told him I planned to use my DG silencer and provided the dimensions for the collar, have not tried to fit it yet though.

This guy builds amazing pipes. His website is down for right now but its mike at cpi racing. For future reference


Someone hand built the pipe on my Z. I think it really hurts performance all around. One day Ill buy a stock or dg to replace it. Ill have to get some pics of it. Awesome build btw!

Well, if it was shipped by UPS, they can in fact screw up a ___ dream . . I paid almost $2,000.00 for a NOS hood for my 69 Boss 302 and it was still packed in the orig Ford shipping box, and when it arrived, it looked like it was dropped off a 10 story building...and then run over . . Luckily I had it insured for full value but it was a hassle getting the money back.

As I look closer there was filler rod used on all of them.

I have watched Harry Klemm and my other friend Lee Scheffers make pipes and they both used some filler rod . . Simply butt welding a pipe makes the area thinner and weaker.

That all said the pipe was $404.58 including shipping and paypal fees...

Screw the ugly welds, that's still a pretty good deal these days as you mentioned.

...so let's step back for a minute and remember that we get what we pay for.

Well I gave her $20.00 on felt I only got $7.53 worth.

(by the way I did see that one before, so you're not the only weird one on here)

Oh goodie, does that mean we can talk about oil now? . . Your exhaust flange might slip on easier and be more resistant to corrosion and seizing if you use some, especially if it has high levels prefabulated amulite...

Yeah you might have mentioned the price first so we had some context.

I was wondering why he didn't sand off the fisheye pinholes.

That's actually a better deal than I gave it credit for .

That being said, pull that dent out. Its still ruining it for me

I'll get on that dent Chop Chop, but first I need to find a three prong 220V single phase plug for my TIG welder. Should be common as perro caca but I'm being told 4 to 5 weeks to get one in the industrial mecca of all of Mexico, WTF??? You guys that can mail order a hood (dented or not) to your front door have no idea how good you have it...

Hey EL . . actually we do know just how good we've got it, that's why we choose to live in the US instead of "Southern California".

Don't they have Home Depot in Mexico? or a welding supply store or commercial restaurant supply store.

[ironchop]

I can't believe you can't out three blades, jb weld the wires to the blades, and carefully plug it into the wall.

That's what a real Mexican would do
