Inconsistent burble/pops
Hello, currently driving a FL coupe. I have a RedStar downpipes and a 300 cell cats installed, plus a secondary cats delete. I was wondering why the burbles and pops on downshifts are so inconsistent? I usually downshift at around 3k rpm, and sometimes it gives great burbles but sometimes there is just nothing. Is there a specific RPM that I have to be downshift at?
What's weird is that I remember the car being a lot more consistent before, but ever since I had the car do the B service, the burbles became less consistent. Might just be placebo but did anyone else experience this?
