I know this is an older post but when you purchased the FI CBE did you go with the resonated x pipe and resonated mufflers initially? Do you have a pic of the install of these other resonators?Ever since I installed the FI LDPs the droning and overall volume increased tremendously, it sounded crazy but it was too loud and raspy. Too muh of a screamer for my taste. It already had a bit of droning just with the FI CBE, but with the LDP added it got bad. I was quite disappointed with the FI exhaust which is so highly praised here in the forum.
Spoke with Kevin @Fastintentions and he said I could try to get a local shop to install resonators (voiding the warranty though) or order a new mid pipe but I decided to go ahead with the local shop.
Ordered these from Z1:
Picked the 12', was afraid the 18s were going to be too quiet.
Got a local shop I trust to install them and ****, it sounds freaking amazing now. It got a deeper tone, its less loud but still very noticeable, especially from outside. The guys in the shop did a great job.
Also had them do a transmission fluid change and indeed the car shifts smoother now (66k kms). New spark plugs too in preparation for a Specialty Z tuning later this spring. Also new belt (indicator was getting close to edge) and new brake fluid (5.1).
Anyways, I digress. Moral of the story, get resonators unless I like a screamer![]()
