k guys made my choice for the headers im gettin just wanna double check a couple of things w/ u guys first. ill be getting the headman long tube 1 5/8 w/ three inch collectors part number HED-68460 on summit. first question is the long tube r better for torque correct. second do these come w/ all the brakets if i need any for mounting. and probably the most important two questions... will this cause me to run lean (no new cam or heads just headers w/ no smog and exaust no cat) and the other part will these go on w/ my stock replacement platinum plugs and msd 8.5 super conductor wires?? oh and is the ground clearance gonna allow for a daily driver since i dont have it lowered any i dont see me having a problem as long as i stay away from large speed bumbs but just wanted to double check... thanx guys!!!

Hmm, well I just helped my friend install his new Hedman's on his '00 Trans Am yesterday. Man those suckers were alot lighter than the old manifolds. They don't come with the header bolts that you'll need. You could use the regular bolts that came off your old manifolds, but I'd say your better off in the long run to just get new bolts. I'm not sure if they come with the gaskets, I think they come with the flimsy little cardboard ones, but I'm not positive. I never really asked my friend, due to the fact that he just reused the stock manifold gaskets which worked fine. I see no reason as to why they would not go on because of your plugs and wires. If those happen to get in the way, then simply remove them. I know my friend had two spark plugs in the way that we had to remove to get the driver side header in. The one problem we faced on the passenger side was the engine oil dipstick, you'll have to remove that. His just twisted right out. Might be different on yours. Also, my friend had to grind a small portion of the engine block to get the driver side header in. I'm not sure as to how any of this will work out for you, but I thought I would try to help you out where I could. But all in all, the results were awesome. Right now my friend just has the headers on, and then those run into 3 ft long pipes which have a turndown tip at the end. So technically, he's running true duals right now, just slightly ghetto. Only until he has enough money saved up to buy the rest of the exhaust. But good luck with whatever you choose to do. And I hope this helped some.

1. yes long tubes are for torque
2. contact headman to ask what is included in the kit
3. shouldnt make it run lean, but it might, just something you have to find out.
4. shouldnt impact your sparkplugs.
5. and im not sure about ground clearnance.

ground clearance will most likely be reduced. Might wanna get a y-pipe too to make it all fit. If its a cheapo gasket get a new copper gasket. New bolts. All of which are easy to find. Would he need to rework his pipe given that they are long tube?

k thanx all....just hope i dont run too lean after the swap id hate to put on headers and them hurt more than they help but i dont see that being the case. and yeah im gonna spend the money to get a custom y pipe bent...anyone here had to go to a negitive or reverse egr or what ever it is after a set of headers is on??

theres the thred that lists the part numbers for em if ur interested...they say alot of people use them w/ exaust that would cause a real low back pressure

i have headman shorties 1 5/8 primaries and they came with the all the hardware except the bolts. from what many have told me, long tubes will extend down further than the bottom of the car, and will be the first things to hit the ground when close enough.
i had to cut away a small section fiberglass that is part of the A/C system (on the passenger side) to get the pass. side header to fit without touching anything. you may/may not have to do this.
