Stainless Steel "Tube connector Stack-Breaker"
Looking for peoples opinions on these that have used them or are using them on your exhaust.
Thanks, Chris This "tube connector stack-breaker" makes it very easy to separate two 3" pipes. Used on agricultural equipment when you need to remove a stack to get a piece of equipment inside a shed, and in racing when you need a quick take-down method. Carbon steel for easy welding to standard exhaust pipe. This assembly consists of two special mating flanges and a quick-disconnect V-band clamp. https://us.st11.yimg.com/us.st.yimg....4_1983_8643239 |

Looks flimsy to me..... I like these - same concept, just beefier.

Looks like a v-band connection to me...

Yeah, wouldnt you be better off just welding v-band flanges on already existing pipe? I have seen these set ups on tractors and the like, but take into consideration the EGTs of a diesel motor compared to a rotary.
|
I was just using these as a example. Yes, v-band clamps is the term I was looking for.
|
What gauge stainless is the tubing and how much can you get them for? I've seen 2.5" stainless v-band assemblies for around $25 online.
|
Yeah, how much are those things?
Summit Racing sells better looking ones. Be warned...all of the guys who have them on their cars complain the v-band always leaks. :( -Ted |

I would not recommend the ATP V-bands. I found the fit on standard tubing to be very loose so I had to fill a lot of void in with the welds. Also, they are mild steel. For the cost I would expect stainless.
The Vibrant V-band assemblies seem to be better and have an inner lip which helps prevent leaks: http://vibrantperformance.com/catalo...8e970022188745 |

Are you very happy with them? I can see the difference in those compared to others. Not Cheap either! CHris |

Thanks, Chris I'm using 2 3"er's on my setup. They fit nice and the clamps are sturdy enough. I used them at the bottom of my DP and right before my cat back so I'm not really worried about EGT's. I did use different nuts on the bolts. |
Aaron, those vibrant ones look nice!!
I didn't have any trouble fitting the ATP ones my piping though, they slipped right over and I just ran a bead around them. To be fair though, the bends I was using in that case were also bought from ATP. Mine don't leak (yet, crossing fingers lol) either and that down pipe had been on and off a couple times during the end of the season. |
So are the v-bands worth looking into or are flanges still the best way to go?

I have all v-bands on my exhaust, and it's a GREAT setup. The part pictured here looks a little flimsy to me.
FWIW I make "permatex gaskets" by running a small bead of exhaust sealer on one side of the v-band connection before I bolt them up. Stops any slight leaking and doesn't make a mess. |

CHris There's nothing really wrong with the standard v-band setup that ATP sells, but they could be better. When welding, pay close attention to heat and check for warping. Clamp the assembly tightly closed during welding. If they are a little warped, you can flatten them with some sandpaper on a small plate of glass.

They are great as long as you take the band off the right way.
V-bands were designed for quick removal for those who do this often. I've seen instances where they seize and basically need to be cut off. They were not meant to sit under your car for long periods of time (i.e. years) without ocassional removal. Maybe you can slather some high temp grease or anti-seize for this? I'd prefer some 1/2" thick flanges for street use myself. -Ted |
V-Bands tend to seal better when there is a flex pipe in the D/P
