Looking good Alex .
By the way the other thing that most of the big single tuners started doing a few years back was tapered headers and reported good results then they started messing about with power bombs (again )

I am finding your fabrication very interesting.
All those lovely bends in the exhaust til it got to the sharp turn into the end can.
That will be niggling at you until you engineer it a bit more.
I am very jealous of your all round skills and knowledge.

Thanks!
There's a whole world of stuff out there isn't there. TBH, I've not looked into tuned lengths or anything like that. I was planning to have the facility for removable restricters of different sizes in the mid section, just in case anything horrible comes up when it comes to dyno time. I would drop a few BHP off the peak power figure in an instant if I gained low end tractability

Sadly, although I could make it slightly smoother if I were to do it again, that sharp bend couldn't get much better as it has to make such a tight turn to clear the shock.

Before the frame gets painted it'd be good to have you cast your professional eye over my amateur fabrication and give me an objective opinion - My welding has got a lot better since I last made an MT exhaust...



... but I've still got plenty to learn from someone who knows what they're doing!

Are you MIG welding with stainless wire?
Its not the worst welding Iv seen! Are you using Argon shield?

No, it's all TIG, all pure argon. My early weld in that picture was done with my first TIG welder, a basic scratch start unit.

With lots of practice and a Kemppi set with high frequency start, thankfully the welds are a little tidier now...

[Yoof]

Certainly is compared to that exhaust!
Iv been doing allot of TIG recently welding an offroad buggy up at college, prefere it to MIG, just cant afford one myself

[Franc]

I have a small TIG welder here.....never gotten to use it, and if I don't soon its going the same way as the rest of my tools...........EBAY.

[Mr Kay]

Back at college I did gas, arc (stick), spot, MIG and TIG. Always enjoyed gas and TIG more than the others and when I could afford it I bought my first set. Now I'm getting better at it, I really love the control you have over the weld, I love the fact that it's quiet and there's no smoke. It's also very versatile - skill notwithstanding, my Kemppi will weld almost any metal that's weldable from wafer thin up to 6-8mm.
Ali is a bit of a different animal, because of the AC switching it makes a fairly aggressive buzzing noise and the weld behaves very differently. I've found that I can get everything set up and start running a reasonable bead then all of a sudden it'll turn to sh*te. There's quite a lot of ali components to make for this project so you can look forward to more photos of pigeon poo welds!

That looks like my old Guzzi project that you had off me Alex. I recognise the stop for the long Cali prop stand that I made on it. Plain and simple old stick welding that was, on my old plant.
My new "inverter " stick welding plant is a revelation, super smooth, I can tackle 16g without fear, and with stainless rods it does a fair job on the shiney stuff.
I would still love to graduate to Tig though. Never have liked Mig. Ok for some things, but never looks pretty, and difficult to get any real penetration.

It is your old T3 Pete though the Le Mans wears an identical item.

As I said, I never got on that well with stick but did find that the stainless dissimilar metal rods allowed me to get reasonably strong and neat welds, they always seemed to run better than the normal rutile iron rods. The slag chipped off far easier as well.

I'm afraid your stand stop will be going as I've changed the arrangement of the stand slightly

The main thing i have found welding Ally is to make sure it is spotlessly clean.
Use a zirconiated tungsten to get a good ball tip.
Ally soaks up the heat so you need a lot of power at the start, gradually decreasing as the ally heats up. Any large parts its best to pre heat before welding.
Sorry if i am telling you how to suck eggs.
Your welding is looking great mate.
Oh, and if you need any rods ect, give me a bell.
