    my s366 turbo's have a 3 in o.d but the id is more like 2.5. so should 3 inch or 2.5 in pipe be used
    to go to the merge .the merge will be 4 inch to go to the inlet of the intercooler

    Nope not off hand but I'm sure if you Google a little you can find one otherwise pm me and I'll get you in contact with a guy who can make you one . It's a shop so I don't want to toss up ad when they don't advertise on here .
