I bought Kooks. Because they are the best headers you can buy. My Saleen supercharger on the other hand............is a different story. Soon gone(thank god )

The HP gains appreciated with Kooks LTs about the same as what you will see with the Chicane Intercooler. Torque isn't as strong with the LTs though. Figure Kooks LTs will cost you about the same or more than a Chicane Intercooler and install on the intercooler (in the hands of someone that knows what they're doing) is the same, if not a little less than the LTs. In summary,if you haven't done the intercooler upgrade yet....don't mess with the LTs .
Almost forgot mention....if you're a fan of noise....forget everything I just said
I love my Kooks headers. A very clean install and I actually have more clearance on my 05 than with the factory manifolds. When I first installed them, I was running a 3.6 pulley. I actually lost horsepower and torqueon the dyno. As soon as I switched to a 3.4 pulley I gained 52 rwhp! It's almost like the Kooks made the exhaust system so efficient that I needed a little more boost on the front end.
Yellow is just mad because he took his car to his world class tuner that is the best at what he does, and with all his mods he managed to put LESS RWHP than a STOCK S281SC, and then refused to get a tune elsewhere to correct it. Hope your tuner has more luck with your cobra engine!
