Does this sound right? Stillen HFC & CBE

ben1620

I got my stillen cats installed and I wasn't expecting any rasp. Stillen CBE has been on the car for a year or so. The cats were used but look great. I'm just wondering if someone with experience could give me their opinion. I've been reading posts about it and have heard people say they didn't have rasp with the same setup but I'm not sure what I'm listening for. Its quwithin I'm gentle with the throttle. Any more than 25% throttle will produce sound at about 4600rpm. 50%+ throttle will produce the noise at any rpm


Also wondering if a y pipe will help. I also read that the stillen y pipe isn't the best choice. Any input is appreciated. I also hear some noise while decelerating around 3k that is not in the vid; to describe it i would say it kinda sounds like an AC hissing sound. I may try to get some driveby vids if I have time today. Thanks

UPDATE: THANKS for all the help. Im convinced this sounds like it's supposed to and I LIKE IT.
