Post by: N2TRUX on October 12, 2010, 09:18:05 pm: Is your truck stock or modded? Is it lowered or lifted? A stock motor with a small 4 barrel is going to need a lot less than a bored, stroked and cammed motor. If it's stock height or lifted, long tubes are fine. If it's lowered you want to go with mid length or shorties.

Give more details and you might get more input.

Post by: Psycho71 on October 13, 2010, 10:03:43 am: I like Hookers myself. I generally run the straight comps with 2.5" exhaust. if I were to get more radical, the super comps with 3" collectors would be the ticket. I've heard good things about Headman too, just always bought the tried and true Hookers.

Post by: Swims350 on October 13, 2010, 01:09:30 pm: well if you buy the painted ones they'll rust and burn the paint off right away, so I'd go ceramic coated or stainless. ceramic is expensive, and you can buy stainless long tubes on ebay for about $160, that's how I'd do. I run the cheap headers all the time, flowtech, dynomax and summit brand. They work, they fit about all you can say.
