Performance Kits and Exhaust

[imruninl8]

Thanks for the info...seems that I"m starting to narrow it down. All the ads are claiming 15HP or better performance increase on the exhaust change, and another 14 or so for the air filter change. Right now, I'm guessing that the Zoomer or SMA's may be the best choice for me, as I'm not looking to get a loud exhaust, but something with some tone to get rid of that Toyota feel that the truck engine currently has.
I did drive it before I bought it, but not at 80 MPH...where you can really hear the engine's tone (or lack thereof), and feel the loss of edge in performance that comes at that speed. Thanks again...
