A cat will be the biggest whistle killer.
I say don't put a muffler on unless you want to get rid of the full throttle v8 sound when your going full bore.
Throw a cat and leave the muffler off and the sound is only really loud when you floor it.
I was trying to get my turbo to whistle so when I bought the 03 one and had it out on. Inwas heart broken to hear barely any whistle... So removed the cat and muffler. But I might put cat back on too because of whistle but I'll leave muffler off and suggest you do the same for great sound and minimal whistle
