have these been proven to actually add any noticable power to the 400's?

Yes, they have been dyno'd and shown a average of 11HP increase and 5ftlbs of torque. Granted a dyno is just a tuning tool and cant really be held for dead accurate numbers.

Friend of mine installed them on his LS400 tho (needed some slightly modification) and noticed an average of .1 to .2 decrease in overall 1/4 mile times over a 16 run day


these paired with a high flow cat ( or no cat) and a nice flowing exhaust system, you should feel a little more power

Wow... I guess you'll be busy pretty much the whole day this weekend.... Please do take lots of pix and necessary step by step for everyone. Every installation is different and there always seem to be something that gets in the way sometimes ..... Looking forward to your update.

nice mods...installing them is not so fun though. one reason i passed on headers was due to the installation.

headers are always going to show a gain over stock exhaust manifolds b/c it's 4 pipes running into a collector vs 1 pipe with exhaust coming from 4 ports into a collector........
TYPICALLY lol
