Looking For Mild Steel V-Band's...

This is pretty close to what mine look like. But alittle different...

Gave up on trying to MIG weld them. Got some .023 309L stainless wire. That didnt help things at all. Just cant make a nice enough weld that either wont leak or doesnt warp the flange (ruined a flange from warping it...not a cheap mistake).
Took them to a local machine shop. Cut some 2" long pieces of pipe to stick in each one and had the TIG it. $60 for 6 flanges. They look perfect, wont leak, and they told me they would TIG the entire y-pipe when I was done. I can MIG the pipe to pipe easy...but for another $60...Ill have them do it.

Cool man. hey..if you can afford it, get a couple extras. That way JUST in case one gets furbar'd, you wont have to wait for another like I did.
If you dont mess any up, you can easily sell the left overs to someone. I wish I would have gotten an extra...then again, I wish I would have just had them tigged in the first place. haha.
You still gonna try to do them yourself?

Mild Steel 2.5 V bands
Or Youngs Performance
Also a quite a few on ebay. I've bought some from this company, they ship fast and have sizes from 2.0 to 4.0 and all stainless.
Stainless V bands
But if doing exhaust work and not doing any fancy turbo work, stick with pressed flanges. They come in all sizes and in MS or SS. Nearly the same as a V band but more economical especially if you opt for the MS. 2.5 to 3.0 should cover anyone doing some true duals.
Pressed flanges and clamp assemblies

If exhaust work is all your doing then pressed flanges will be absolutely fine for quick take down at the track or where ever you need a quick detachment point.
I'd only use an expensive V band on a high pressure tube like a turbo crossover that really needs to be leak free.
I usually run pressed flanges from the downpipe back, no issues at all.

Well I went ahead and contacted the company in the link your provided. Got a few things figured out and a few new questions as well. First off, the pressed flange is what the guy there recomended for my application as well. In fact, he has one on his truck and is doing the exact same setup I am. He measured one over the phone with me and told me they are measured ID (inside diameter). So, that means it slips over my 3" tube I'm using. So that solves that. Now, I asked him if I really wanted to use a V-Band flange I could, right? He said no because they are only used in a turbo type application and something about both mating surfaces have to be in a v configuration to get a positive seal. Apparently that doesn't apply for normal exhaust type tubing??? Still don't understand that part as I see others using v-bands on normal exhaust setups. Either way, I'm going to give this pressed flange a try and see what happens. They don't make them in 2.25" so I'm going to just get a single 3".

I have a Jeep too, and made a custom exhaust out of all mild. Ive had it all submerged in water and mud almost up to the hood and the pipes are still in good condition. Just clean it off after you wheeling trip.
I asked about rust on those flanges when I talked to dynatech, and they said it wasnt really an issue. The guy told me I could tape off the sealing part of the flange, paint the back side of it, and that would help. Because the sealing sides fit so tight and flat against each other, that they dont easily rust. So Im going to hit all my weld areas and the back sides of those flanges with the highest temp paint I can find and just hope that it works out forever. haha.

So, I noticed that they make these "pressed flanges" in both carbon steel and also stainless steel. I would like to get the stainless steel as it is only a $3 difference however am I going to run into welding issues with trying to weld it to my current aluminized tubing?

A clamp like I am using will work just fine on exhaust...as will the stamped ones I imagine. Its amazing the amount of compressive force you get with the two flanges and the "V" shaped clamp. Before they are even all the way tight you cant even rotate the two flanges anymore. These things are great.

P.S. Its so nice to have clearance again... and an easy way to connect/disconnect the exhaust, without dealing with slip fits...
Sorry Im kind of pic whoring...just figured Ide show ya an assembled pic or two...
