hey all,
i need some help with this


i have a N54 e92 with AR DP, BMW PE and need help getting rid of the RASP we get at about 4k RPM and up,...below that , it sounds beautiful
the AR Down Pipes are catless, and the secondary cats are still there, but i just cant get over they nasty raspy, ricer sound above 4k, i have to admit, i like it sometimes, but for a everyday thing ,no .. im looking for a deeper more refined sound, ive heard people say add resonators, ....
what im not understanding is if i need to remove the secondary cats, and replace with resonators, or add the resonators, in conjunction with the secondary cats. ( id prefer the latter )

ive checked youtube for sound clips but only get them at cold start or cars at stand still, which..doesnt really help me,

can any one clear this up, along wth getting some sound clips as well? would really appreciate it ,

also if its adding resonators with the secondary cats, which resonators are the best to get

A resonated x-pipe may do the trick.
