    Mid tube headers + 02

    My friend has an exaust leak on the right side of his car's manifold... So he was thinking of replacing both manifolds with mid tube's

    this is the link to the mid tubes.

    Do you think that he will run into any issues with fitment and will any fabrication/tuning need to be done?

    or do you think he should go with shorty headers?

    I dont believe that there will be any placement issue and no tune is nessary.

    Shorty's are a waste of money IMO... Tell him to go with long tubes and an off road Y pipe. The catback will bolt right up to that. And a tune will probably be ideal if you get rid of the catalytic converters.

    I was thinking that. Which long tubes should he go for? Will he have to dyno it or can it be tuned just by computer?

    A mail order computer tune should be perfect since it appears he is mostly stock.

    There are tons of different companies that make headers for our cars. The #1 rule for header selection is get stainless steel. The # 2 is do NOT get SLP's. They are excellent tuned length headers, but your under body clearance takes a nose dive once installed. I bought mine off of Ebay a few years ago. They were brand new OBX long tubes and they were cheap compared to whats out there. Everyone is going to have different opinions on headers, so do some searching around on here and you'll come up with what's right for you.

    Both links you posted up are shorty headers. Don't bother with them. Get long tubes. All long tubes make roughly the same hp. Go with what your budget will allow. Personally I recommend stainless. Kooks or American Racing if you can afford. There are some decent stainless ones on Ebay but if they do not include a y pipe you may need a custom one fabbed which would negate some of the savings to be had there.
