    Well, this will start a shit storm, but I prefer tuned length long tube headers, that is why I decided on my ceramic coated Hookers. However, I think the difference between them and unequal (non-tuned) is less than 5 HP. I think it is better to have equal length exhaust tubes as well as equal length plenum runners, eh? There are a lot of cheap headers out there, and they will make a big difference over stock manifolds. Can't remember the name of the current favorite non tuned headers, but I will post later when it comes back.

    Avoid the SLP headers (either pair) at all costs.

    When I was doing my research on headers, this was one thing that made my decision to buy the Hookers, them being tuned length. Maybe not all Hookers are tuned length? I know the set I bought are.

    unless you are going to be pumping massive h.p the difference between between the two styles of headers wont net much h.p.
    stay away from slp product.

    Strait from Thunder racings website:

    Hooker's 2253 is a tuned length 49 states emission legal long tube header for your LS1 F-Body (Camaro and Firebird). All emission control devices are accommodated with this header. This header is built with 18 gauge 1-3/4" primary tubes that improve the engine ability to breathe over the stock manifolds. Tuned length primaries and long transition 3" collectors increase exhaust velocity for huge performance gains. Part number 66-2253-1 comes with a Metallic Ceramic Thermal Barrier Coating, This coating provides improved thermal stability reducing the possibility of header cracking. The high luster finish is rust resistant and acts as an insulator resulting in higher exhaust temperatures within the system to increase performance while lowering the under-hood temperatures.
    I don't care what they say, anyone can look at the #2/#8 primaries and tell they are not the same length. Marketing at it's best.

    I think we should change our motto to LS1.com helping noobs steer clear of SLP since 1998.

    Did you drop a piece of string down the pipe to measure the lengths before your install? A 2D picture won't show the curves/length of pipe like looking at them in reality. So, you're saying I bought the marketing hype, eh?Maybe I'm wrong about tuned length. Maybe someone should call Hooker and ask them exactly what they mean by "tuned length". Could be that the tubes are designed for optimum exhaust pulsations to scavenge better, and maybe that would be optimized by tube length differences.

    At least we all seem to agree to not recommend SLP headers....
