Does this sound right? Stillen HFC & CBE

ben1620

Thanks for the help all.

Heres the best i can do on new audio atm. You can hear the rattle from 0:10 til about 0:14 but I need some help to see if both cats sound the same. It is MUCH more distinct while driving, like in the first vid, and will do it at any rpm with enough throttle. This may be evidence suggesting it is normal but if u don't know it's "right" then it sounds "wrong". I want to make sure there are no obvious issues with the install or cats. Also i found posts discussing the same issue with the same setup, im which ppl have said they hear zero rasp and rattle.

I can deal with it if it's normal, but will try wrapping it and will get a Y-pipe if it helps. Or would consider resonated cats down the road. I need someone to drive by or next to me bc all I've heard is from inside the car.
