Alright guys, i finally figured out the problem to the age old issue of getting HFC without all the drone.
Tony at FI makes Resonated HFC for the Coupe guys in the 2.5" variety but hes never done it for the sedan guys in the 2.25" size. this will line up perfectly with my existing FI Catback system. Gains will be the same as the non resonated HFC but the interior drone will be cut in half. Exterior sound will remain essentially the same as a regular HFC. He is ordering the 2.25 resonators from the supplier right now and assembling my system sometime late next week.
. Tony said if he gets enough interest from everyone he might start offering this as an option.

UPDATE: They finally came today pictures below. overall first impression:extremely high quality. Expect nothing less from FI. My Catback was the same way. im going to try and get them installed after work today. will keep all of you updated

 

Nice job, subscribed to hear after results/video!

Awesome, I would be interested if I heard it on a stock exhaust.....

 

Yup.

You're not the first

 

Looks like Tony lied to me then.......
