well, you could keep the resonators and just replace the mufflers. flowmaster delta 40's can give you a nice throaty sound w/o an annoying drone.

i'm using a NX kit on my GS 300 with only a 35 shot for now, just to test and make sure all the connections are working. the only problem is, I can hear the solenoids engaging, but no change in engine sound is present. any ideas as to why that is?

thanks.

did any of your guys cars have this symptom. the car idles at like 1600 rpm when starting it when the motor is cold and this lasts for a few minutes, thanx in advance

yeah, i have a 98 GS 300 and when it hasn't been started for a few days (or just overnight) and the temperatures have been around freezing, the RPM's idle around 1200-1400. It doesn't seem to cause any issues. I tested it once and noticed that after the engine gets to its normal heat range operating temperature, the RPM's drop back down to a normal 400-800 RPM idle.

hope this helped!

what year is your GS 300? I have a 98 and built my own custom cold air intake. the car has about 61k miles on it and it still runs fine. you can definitely tell a performance difference in the engine at about 4200 RPM's. It's a pretty easy install as long as you know what you're doing. my friend and i did the one on mine and i've loved every minute of driving it.

yeah, i have a GS 300 with flowmaster mufflers and they sound much better with the resonators removed. lexus puts in some pretty large resonators and with those gone, people will definitely know that a V8 is coming. i think magnaflow may offer resonators that you can put on if you want a real bassy sound.
