    The tti's are probably the best bet all around.
    If there a bit much for you now, wait on it.
    The 1-5/8 headers will do. Just keep the exhaust as free flowing as possible.

    As a member here once said about this;

    Of course, everything is in the combo. What is yours?

    It's over 400 ci, I would go 1 7/8 minimum regardless of use, on the advice of my engine builder.

    Are you talking the 5116 headers?

    they hang very low and will scrap on curbs and speed bumps. Eventually the low pipe will become over 50% crushed and when it reaches only 30% of what it used to be, it will be leaking from the pipe getting worn through...

    Other than that, they're great....

    a 1 7/8 header over a 1 5/8 will make more than 10 hp. we changed from 1 3/4 to 1 7/8, gained two solid tenths and two MPH across the board!!!! figures to be about 20 hp.

    Look to Hedman.
    Yes, headers are expensive, at least the kind of headers where you actually make power from. Real headers cost money. Custom headers should out perform OOTB headers and will cost 3X's the price easy of those expensive $700 headers you want to avoid.

    The best header for you and the compromise are tti headers into a 3 inch exhaust.
    It will perform well.

    Right on rumblfish360 well said, that's everything I've been told. Spend the money on good headers. No one likes to spend that much money on headers but from what I keep hearing it's money well spent.

    I hear ha! Was way back I spend 3X's the money plus when going from normal headers to Hooker Super Comps for my E body. The thought of (the then expensive) $300+ headers was killing me. But once in.... Ohhhh boy! Never again will the one size fits all be used, NEVER AGAIN!

    The A body isn't as lucky as the B & E body. It's Doug's or tti.
    Doug's for the general and high performance engines.
    TTI's for the high performance engines and they can really help with the higher HP search mills.

    It's so worth the money!
