Hi all, new member here
I already have a cat less UEL header installed on my GR86 and I'm looking for a cat back that's just a bit louder than stock but with 0 drone!!
Not sure there's such a thing (other than the stock one) as all that I've tested or heard so far had some level of drone/boom/raspiness.
Invidia Q300 (on my ex-GT86) was the closest to my requirements I could find, but the joy lasted until the first track day, after which it developed some "issues" (not really drone but a noticeable shift in tone/volume) around 2.5k rpm mark.
