    I did headers, and they made a HUGH difference. I did it with the exhaust,. and I was really happy with the outcome. I'd bet I gotta 30+ hp improvement with the 2.

    Well headers can be bought for under $100 depending on what you get and want.... then you can go from there and spend way more. I spent $325 for Edelbrock TES headers with AIR and the Y-pipe... Some people say they don't do a thing, others say they do.... I'm one who says they can add horses and do more then that if done right... not to mention they could greatly improve the over all air flow which could increase performance. But anyhow at the very least they look cool and sound cool! [​IMG] [​IMG]

    i would recomend headers for anyone looking for more performance from their engine. They flow better than the heavy stock cast iron manafolds and improve the sound of your vehicle. Some people complain about leaks but it hasnt really been a problem with mine. You can get a set of headers for less than $100 from summit or dynomax or you can spend a little more for a set that are made a little better or coated with something to keep the heat down. Headers are especially good if you have or are planning to do other mods to the engine such as and intake manafold or cam change.

    I got hooker super comp headers, and I paid little over 300 for them from summit, but there are cheaper headers on the market.

    I have had excellent luck w/ any Hooker Header... you can get them for pretty cheap... like 130 and then either wrap them or have them dipped somewhere and you will be set. I also had a pair of dynomax headers that were pretty decent, but suffered from some leaks and need a ding and bang here and there to fit, but I believe they have coated ones for about $200 or so if I remember correctly. I also looked into Flowtech Afterburners and they look decent too... I still haven't decided what way I'll go, but I'm gonna use manifolds till I swap the motor next next spring anyways.

    Don't wrap your headers if you live in the rust belt. I've heard that they hold moisture and salt and rust out your headers very quickly. Most header companies won't warranty their headers agaist rust through if there's evidence that they were wrapped. [​IMG]

    Personally I'm going to go with a set of stainless headers/exhaust. I don't care how much they are because the way I figure is that they will never rust and will literally last a lifetime so I won't have to spend money on them again. Any disadvantages to stainless? (ie heat?).

    You don't really want to get the cheapest ones you can find. Chances are they won't be a good fit. I run Heddman headers on the blazer. Awsome clearance! And the camaro has edelbrock. Both fit really well and you can get to the plugs pretty good.
    People who say that they don't offer an improvement are prolly running cats. But they've improved everything I've ever put headers on.

    I've got a mind like a . . . a . . . what's that thing called?

    Had headers put on mine, dynomax, same as the mufflers, however I have no idea if it made any difference it was done at the same time it went from a single to a dual, by dual, i mean dual cats/etc... not just a Y pipe. I also had my pipes turned out behind the tires, however I did leave more than enough room there so I can go up to maybe 38"'s if I ever get daring...

    Ture Duals have two cats !
    Jump the neibors fence and get you some cats.
    Or go to the back door of the resturant, and tip'em good.
    Tests have proven headers will loss low end torque, its up to you spend money and lose power.
    Good luck

    i was under the impression that "cats" were catalytic converters, and that they had nothing to do with wether an exhaust was dual or not. I thought that to be true dual exhaust you had a seperate exhaust system for each side of the engine, (no y pipe connecting). are you saying a vehicle with no cats can not be considered true dual exhaust?

    Yup Harry you said it... there are a whole bunch of things that people frown on w/ the wrapping, but the way I see it is if you buy cheap headers well you can always replace them down the road... although that wrap is pretty spendy too.
