see the sig below... i have no issues making 445 with NO TB yet through 2.5" from the collector back. i have changed my setup to the SW 3" X pipe to the factory Z06 exhaust to quiet it down some. i don't know what this will do for me yet but with the ported TB and exhaust mods i should pick up at least 8rwhp... there is something wrong... you will get it figured out... good luck!!

The high stall A4 is the only thing that saves the shorter headers. I understand that you have what you have, and you probably don't want to change, but that doesn't mean that you are not losing low end hp. And your package may not be hurt that much by losing the low end torque.
Our headers are what they are. They make more low end, and that is a fact. If you don't think that it would help your package, then that is ok, but just knowing that there are cars that go fast without some particular mod, doesn't "Negate" the value of a particular mod.
Thanks

Do a leakdown test on the car.
Think you will find cylinders at 10% or more cause of the valve seat problem with PP heads.
Pulled a set off a car this past week.Motor had 2 hours of run time and EVERY cylinder had +10% leakdown with a gapless ring.Turned out to be the valves leaking badly on random cylinders.
Just a hint for ya.

wow if you lost 2 quarts already you have a serious problem. its not going to be your major hp loss but im sure it does take away a bit. you should start another post about this issue to see how many come foward to see how common of a problem the oil consumption is. There were alot of pp guys pulling heads in the past year. i hope you can do it yourself to save $$$$.
