its probably you....almost impossible to have less power with the mods you have....sounds awesome doesn't it, I should know...Check the sig...

Do you have the tubes and K&Ns to round out the package?

You'll want to list your particular year model & make; also, which brand of cats. Sims?

Wouldn't he have to get his supercharger retuned after switching out his system?

R Hummer - on my C5, after freeing up exhaust via long tube headers, my car definitely felt as though low end diminished. Dyno proved that the power increased at the top end. I would rather have the SOTP low end power/torque vs top end. I am now sure if cat back and high flow cat would do the same.. I hope not.
