Ok, it's a simple thing, but it's simple details that make the job better right??? So here ya go, when your building your next exhaust, and your stepping up the size, this is how I make the change from a small tube to the bigger tube...
You need something with a rounded off end. I have specific tools made that work for this, but honestly, you could probably grab yer broom out of the corner and use the end of the handle. Hold it in the vice, and insert it just inside the end of the tube, then lightly tap around, the idea being to tap the edge over the round, not to bash it into oblivion. It might all go over in one pass, or you might go around a couple times.

When you take your time and do it right, this is what you end up with. This particular pic was a 1 3/4" tube fitting up to a 1 7/8" tube.

And if there are anyquestions about just how much you can close up, here a couple shots of a 3" connected to a 4" (not for a bike of coarse). I closed up 1/2" of each piece to make up the entire inch. Hope this can help someone out. Mark.

Fantastic.
Looks like with a little patnence you could make a decent velocity stack too (assuming you didn't have a press handy).

Thanks for the tip.

I'm a total novice when it comes to shaping metal, so I appreciate it.

I saw the photo of the tube with the flared end and thought that would be a nice way to finish the end of the exhaust.

I like that step-up, tasty

I've done a similar deal, but I'm more "resource challenged".

I use the trailer hitch ball in the reciever hitch of my truck to do this with. It's sturdy and convenient and...... round..

Like I said, just about anything rounded will do!!!!

Your specific tool, first pic, looks like a VW 'nerf bar' - LOL
Whatever it takes to get the job done.

Good tech, Thanx.

nice tip.......thanks. I'm in the middle of making a set of pipes right now. Actually I just have the materials, but cannot figure out what I want to do with them at the moment

Anybody that wants to learn this stuff shourl get Fourniers book, or use the resources Covell and Fay Butler have out there. I bought Fourniers book in the 8th grade and use it to this day for reference. ( I better make sure it didnt go down in the flood)
