I had leaks alll the way around the flange welds. The problem I had with my welds, was after I was done, I taped off all the open parts of the header, sprayed soap water on the welds, and blew air from my mouth into the O2 sensor bung. Probably to around $70 or $80 if not more. Its probably TIG welded and would infact kick the price up. Only because of the process of welding the flanges to that piece of pipe. My suspicion is that the price will be considerably higher than the $40 I paid for my kits. If you happen to find a company that sells them with the pipe already attached, let me know.

They seemed like a good company and the flanges I got from them look great. about the flanges and his info is what convinced me to go with them. The ones in summit and probably JEGS are from a company called dynatec.

I would like to order these up today so I may give the ones in Summit or Jegs a try. Sounds like I should look into getting that style rather than just the v-band itself due to the fact that I'm using a MIG to put all this together as well. I understand now about the pieces of tube and their purpose. Trying to figure out which ones are good quality and which ones are not. I'm still looking around for v-bands myself. I just ordered some 309L wire.instead of using the 308 that I was trying to use. no tig welder and no 220 or else Ide rent one. I WISH mine had pipe attached, because Im having a bitch of a time welding the mild rings to the stainless pipe. The kit itself would come with only the flanges and no pipe. I cant remember what company it was, but I called and they said it was for a picture reference only. Ive seen the ones with alittle bit of pipe attached. In most cases I get my parts next day without paying anything extra. You might be able to find them a tad cheaper, but Summit only has a $10 handling fee, and they usually ship that same day. The best place Ive foudn them is Summit.following the link I posted above. If they are good enough to hold boost and use in turbo piping, they are good enough for my y-pipe and will hold my exhaust pressure without leaking and without a gasket. Im doing for the simple fact that I like to over do things. Later looking into building the same setup from the merge collector back but utilizing a bullet muffler instead of the Flowmaster muffler to see how I like it instead. 2.25' from each manifold merging to a single 3.' Muffler is a Flowmaster 40 series and will have a single 3' exiting the muffler with about 36' of tubing and then a 3.5' tip. Don't know if it is worth justifing the cost of the flanges yet though. That way I can build and try different muffler/tip setups from the merge collector back without hacking anything up. The single 3' v-band I asked for earlier will be placed right after the merge collector where the muffler will bolt up to. With two, 2.25' v-bands inline, I'll be able to remove it in pieces without dropping anything. The way the crossmember is setup for the tranny/transfercase, it will require that I drop the crossmember to install or remove the exhaust. Jus out of curiosity but what type of exhaust are you building that would require to use V Bands?Actually, this exhaust is a custom front to back setup I'm building from scratch for my 79' Jeep Cherokee I just dropped a small block Chevy into.
