thats gotta be without cats right, cats make this car sound weak :( great setup u just reignited my kooks exhaust setup now :)

whoa what? you got a 100hp from headers and a cold air intake.

ya i prolly got around 60 with intake and exhuast and if you have someone that knows how to tune this car right you can also get more out of it when its done right.......

eh... i havent heard of anyone breaking 400 RWHP with just headers/intake/tune/catback. the best numbers ive seen there dyno around 375 RWHP, from a stock 300.

So there was 100 hp lost from the engine to the wheels???
