I know Stillen was not one of your choices, but it's the only one I have any experience with.
The Stillen SS exhaust is a little heavier than the others, and a little quiter than the OEM exhaust until you add test pipes. Out of the box it has good performance gains. The dual wall tip looks like the OEM version. It is aggresive sounding at lower RPM and no droning at freeway speeds. True dual/cat back design.
i have the injen ses td straigh tip and love it. again, similar to stillen its also one of the quieter ones out there. i have rt cats on the car as well, and my exhaust note is nice and deep. even when you open it up, she doesn't scream really loud...i love it and wouldn't change it for anything else
although i like the way the stillen exhaust looks, i don't like the way it sounds. i want something alittle deeper than stock, but not much. i also want a light weight exhaust. arn't there 2 differant versions of the injen?
