Default Looks like all my v-band clamp connections leak, why?

Hi, I pulled my exhaust apart and I can see exhaust leaks at all the v-band clamps. The system is stainless and I'm concerned about warpage during welding. Do I need gaskets?

WhatdoIdo??

pictures.

the flanges are pretty hefty and shouldn't warp. are you sure they're lined up in the clamp? some don't have pilot bores that line them up easily.

I've seen some of the cheaper vband assemblies leak, it's typically because the clamp is too big, generally by about hundredth or so of an inch.

Just weld it. Clamped exhausts are crap.

They have the "pilot bores", but I'll recheck to see if they're aligned. How much should I be tightening these things? I don't want to damage them.

they dont need to be too tight. you should be able to get them tight enough with a 3/8 standard size ratchet without straining yourself. basically just enough to keep them from rotating.

Fixed. Seriously though. He must be a looney. Sorry, I don't do v-band or I'd help. I still do donuts

Well, I have one at the end of the downpipe, one at the beginning of the cat, and one after the cat.

If there's a small leak, what's the worst that can happen?

you get pulled over, find out you have warrants, spend the rest of your life in jail getting raped by a large black man named "tiny" only to find out 8 years latter that it was just someone with the same name that had the warrents. but you have grown to love tiny. you brake him out of jail and you both run away to san fran, get married and spend your life together breading show hapsters for elton john.

that would be after tiny died from an rabbid escape hampster that would crawl into tiny's ear while he was sleeping one night and started to eat his brain. target (which would be flukes nickname given by tiny because of all the late night games of bun-darts) would start to collect ball-gags with his paychecks that he gets from working as a greater at the local wal-mart.
