    Heat wrap downpipes

    Hi guys, I just installed my downpipes and wrapped them. I look over the web and found different reactions about heat wraps. Basically most peoples said it will corroed pipes but my dp are ss so that argument is null. Other thing is that the excessive heat will fatigue the metal and break the pipes. I believe that is on headers, on dp is ok to do it.

    What is your take on the subject?

    Here are my dp's

    You should be fine.
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    On a side note, one of the downpipes is not align flush with the 2 bolt flange. Would be bad to tight it like that?
    I thigh it all the way and it close but I se the pipe moving while thight it. Im worried that might mess up the turbo housing. I could try to rotate it but there is not much space there. The bolts align ok but the flange is at different angle. Like 10 degrees off.

    I've still got my AR dp's on the shelf, but just sent my turbo headers and dowpipe to swaintech to get coated for my trans am. Wrapping is ideal to keep the temps down and should help with spool. Ceramic coating does this as well, but usually wraps are a bit better. If you are interested in coating the best i can find(albeit pricey) is swaintech. Just didn't want to wrap my pipes and worry about trapping moisture in.
