Any strong opinions on which aftermarket system to get if I am looking for one that is not too loud and adds a little HP mid / high range with No Drone at low RPMs and is of high quality. Thanks.

 

Carson Tuned.

 

What is carson tuned?

 

This is the exhaust that was modelled after the L-Tuned exhaust but exclusively made by Kimura and only sold through Carson Toyota/Lexus Parts. The construction of this exhaust is much more detailled than it's L-Tuned counterpart.

Here's more info on the Carson Tuned. I also have a post on IS300.net under the Go Fast forums.
