So i just put in a 3 inch apexi noir cat back on my s14 and it’s been rattling pretty badly when decelerating, I tried shacking it and it seems it’s smacking the rear sway bar. i even put cs hanger bay bushings and it still smacks so i am wondering if this is a common problem with putting a 3 inch cat back on a s14 and would getting a adjustable sway bar fix this problem.
Put a piece of rubber around the sway bar and zip-tie it down… had the same problem on my s13
thanks ill try that and hopefully it works
