Test pipes< which brand???

I bought a set of non resonated fast intentions test pipes. I like them and the power gain was one of the best mods. I gained 20 whp and 15 ft lbs of torque in the mid range and 7whp on the top end. Well after a while I got tired of the drone. I also have the fast intentions 18 resonated catback. It would be hard to talk on the phone or to my girlfriend on the interstate but the radio could easily drown it out. So I switched their resonated test pipes. The sound was basically the same maybe a little deeper tone. As far as the small amount of rasp it had before, it was barely noticeable, it was now gone. The drone was entirely eliminated. I can easily have conversations with people and talk on the phone while going down the interstate but the exhaust itself, from outside of the car, is the same volume. I'm very happy with my exhaust setup now and I highly recommend the fast intentions resonated test pipes. Just my .02 cents.

If you can afford it get the Motordyne Art Pipes.

UPDATE: Ended up purchasing the Z1 non-resonated test pipes. All left on my exhaust are the resonators. Car is viscously loud. I know what loud cars are and this became loud. Also very raspy but IMO rasp is a signature of VQ motors. Finally audible at the racetracks and the downshifts can scare the living nuts out of other people driving alongside me haha :P Neighbors hate the volume of the car, cops think I'm racing under quarter throttle when I hit rasp at 3k rpm, and dogs think the aliens have invaded earth.
