    you would have to check the laws in your area.

    some times you can as long as you pass the sniffer, and other times you can't have LT's at all even if you have highflow cats

    Depends on how much you want to spend, i personally think the American Racing Headers are the best to get, but you pay a price for them. I was fortunate to get a good deal on mine that why i got them.

    If i were you i would stick with getting Stainless Steel Headers and Tuned Length

    I think the only tuned length headers you can get are the SLP's, and everyone knows how bad those are for fitment and ground clearance. Not to mention the price, and its not even quality stainless.

    I recently bought ceramic pacesetters LT w/ y pipe from LMP performance. I did all the searching and they had the best deal. You can also get the o2 extensions from them. A lot of people are using the ceramic pacesetters. I plan on getting them installed in the next couple of weeks. I hear stainless steel is great too. Just don't get the painted ones. They are way too hot and will evenetually rust no matter what you do. A guy I know has ceramic KOOKS and loves them. They r very expensive!!!

    I talked to a guy from American Racing and he said that all there LT headers are Tuned Length Headers, including the LS1 Headers for the Camaro/Trans AM

    I hope hes right lol

    Interesting. I wonder if they consider "tuned" lenght and "equal" length two separate things, because equal length headers are quite large and restrict ground clearance by a ton. Just look at SLP's long tubes for the LS1, you'll see what I mean.

    Tuned length must refer to the primaries being designed to optimally carry the exhaust gas pulses and maintain maxinum exhaust gas velocity with each cylinder firing.

    Ya i have no idea if he thinks they are the same or not, i thought tuned and equal length meant the same thing, my fault for giving misleading information.
