i like the ws2 too, i know with my same set up how it sounds due to i built my boys car....we both bough the same defective evo2's when his muffler fell off he replaced it with the apexi and i like it it sounds very clean, it is for sure quite and has been the muffler i have been plannin to use till i came across the vibrant....reviews on them are very up and down so still on the fence, i havent lookd at the cats and i do hav an old stock one...sooo idkQUOTE=Berta;39419437]I'm really enjoying my ws2. Using a vibrant metal race cat and it is the quietest setup I've had. And sounds really good. I've used vibrant muffler before and it was just alil to loud for me.[/QUOTE]
