I need a 4 inch v-band clamp. Right now for temporary fix till I can find the right v-band clamp i have a band clamp holding my down pipe onto my turbo.

What is the measurements of clamp. Ive ordered two online now and neither of them are the right size and they say they are 4 inch v-band clamps but they seem to be a half inch too big but im positive the flange from OD is 4 inches. I just dont understand.

Could anyone lead me to some place to get the right v-band please.

The turbo is an HX40 with the 60mm compressor 4 inch wastegated outlet.

Im using a second gen downpipe which didnt take really any mods. I just cut a 1/4 inch pie outta the pipe and bent it a little more and welded it. saved me 100 bucks. Didnt have to move my trans dipstick or anything

Hello Dean, you need this:

The hx-40 v-band is not a 4" v-band or clamp... Leave it to holset. You have to get hx-40 v-band stuff...

Nope I've already bought and used that one for my Hx40 down pipe and outlet on my 4" turbo. It woks FINE.

I went through the same thing and ordered the "4 inch" clamp and it was too big.

Pape, I have also just bolted my new HX40 up. I can't find a weld on flange that matches up to the turbo flange. I bought the 4" flange and Vband kit. The flange is so big it actually slips completely over the turbo flange. where can i get the right flange? So an HX40 has a 3.5" outlet? the specs say 4". Help!

Yeap, It is smaller than your typical 4" Exhaust V band. guess you could call it 3.5". The vband I linked from air flo is for the HX-40...
