Yahoo...welcome me to the 500whp club!
507whp and 556wtrq. Just look at the monstrous low end torque!


Thanks Eurocharged!

Seriously? I don't think I've even seen a low 500whp E55 touch 600wtrq.
Probably...but that would only make my first gear even MORE useless...lol.
BTW...my exhaust is 2.5" through an X-pipe all the way to the gas tank where it becomes 2.75". I wanted to go 3" but I just don't think it'll make a difference.



But, I think adding a 3 inch exhaust would add power over the 2.5/2.75... all about getting that gas out and gone
When I had my G35 supercharged...I had a 3" SINGLE pipe exhaust on and put down 417whp. I then disconnected the exhaust and put down the same power. After that...I put a DUAL 2.25" exhaust and still put down the same power.
I'm pretty sure a 2.5" DUAL exhaust like mine should have no restriction even at 600whp.

Too big of an exhaust will cause low flow. Low flow kills power
