How to make 2-1 Exhaust Merge Collector

[@marshallmazzarelli8797]

Where can I get that clamp jig you using

[@Smffab]

i got mine from Gizfab, check them out on youtube or instagram. other people do make them tho.

[@trainwreck170]

The blue tool you have to lay out your marks. Did you make that or can they be purchased? And how many degrees do you bend those two pieces?

[@Smffab]

They are sold by a guy called Gizfab. Has a youtube and a website where they can be bought. those bend were 15 deg.

[@wtfftw24]

Again, how do you weld the inside of the "y" which looks like Tig can't reach in? Thanks

[@Smffab]

The way to do it is have more stick out with the electrode and it can reach and get a decent weld.

@@Smffab thanks for the advice buddy 😎👍

@@wtfftw24 happy to help

[@makantahi3731]

i tried to weld 2 in 1 at 10 deg and could not, i had to increase angle to 15 deg, and i barely made( to have hermetic-no leak)

[@Smffab]

These are 15 degrees bends

[@makantahi3731]

@@Smffab i cut pipes at 15 deg and it has more space in the narrowest place than yours-it looks as 10 deg cut. i did not bent pipes, i just cut straight pipes at 15 deg and welded 2 in 1

Very nice work 😄

[@Smffab]

Thank you 👍🏼

[@Ghettocowboy33]

Do you sell these?

[@Smffab]

no, where are you based? There are fab companies that do sell them premade, like Fabco in the uk for example.

Were did you get that cone for the press or whats it called for forming that last part i cant find one lol

[@Smffab]

I had to get one machined, as I couldn’t find one either

[@davinmillington9090]

Is this dual 2" to 1 2.5?

[@Smffab]

[@justinschell2584]

what did you use or where did you purchase the expander mandrel for your press?

[@Smffab]

Just had a friend machine this for me, as I couldn’t find one to buy.

[@romanleal3499]

i use Lisle 32000 for expanding and shaping

[@Jonhenrysneip]

Very nice done 😊

[@Smffab]

Thank you! Cheers!

Hi, where can i find the mold you used?

[@Smffab]

Hi, I got mine from gizfab.com

[@wyattleonhardt3624]

What company makes the blue jig you used for the template?

[@Smffab]

Giz fab. You can buy off his website

[@kathysarmcandy1992]

@@Smffab Late reply, which angle jig is this one? I see there are several.

[@justinschell2584]

I’m in the same boat. I guess I’ll have to do the same. What did you have it made from?

[@Smffab]

This is just made from steel, but should really harden it or make it from tool steel as the stainless steel chews it up a little bit, but it’s fine for now.

[@BlueSkyInt]

Will you sell it?

[@Smffab]

Yes

[@BlueSkyInt]

@@Smffab how can I order it and what is the price?

[@Smffab]

@BlueSkyInt where are you based? Uk?

[@BlueSkyInt]

@@Smffab , no I am in France and would like to have same « Y » but for a 1977 Honda CB350 twin engine. Do you think you could do it if I give you the in-and-out Ø of the exhaust tubes?
