Hey guys, x-posting from driver since i figured some of you would be interested in this

Alright guys, we 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

UPDATE 2: Ive had them installed for about a week now. sound has definately gotten deeper and throatier. car is more responsive and has a smooth low end grunt now and screams in the higher RPMS. interior volumes have remained essentially the same. most that ride in my car didnt notice any increase in Drone within the cabin, but when i get on it thats when the comments start

 

Im down if the price is right!

 

If Tony sees enough interest he might do a group buy on these. no promises though. il try and post vids after install. it would just be the cost of the resonator added onto the regular HFC plus weld time.

 

Those look really good and the J tube is good enough to avoid any CELs... Do you know how many cell that HFC is?

Post impressions once installed!

 

300 i believe. FI guarantees Zero rasp on their HFC coupled with the FI catback system.

 

Dude...this is WAYYYYYYYYY old news????????????!!!!!!!!!!!!!!!!! Search man, I spoke to TOny about these like 2 months ago

 

oh sh*t////my bad, didn't see this was for a sedan, lmao. Good call on these though, will be ordering them for my coupe!

 

lol no worries. yea i ran across the coupe version a month ago trolling the forums and that was what pushed me over the edge to get them.

 

If I didn't already have cats and some crazy numbers from my dyno last night I would be jumping on these!

 

Kudos to Fast Intentions. I love my set up.

 

Any chance of a before and after dyno or no?

 

I might have to pay Tony a visit...

 

No i have yet to dyno my car, but tony said on the coupes adding the resonator to the setup didnt change HP or Tq numbers at all. im assuming its the same for the sedan.

 

Noob question can I fit this on my stock exhaust, do we have 2.25" factory piping? Also is it worth it on a stock exhaust?

 

yo can fit it on a stock sedan exhaust, and the gains should be felt going from stock cats to this for sure.
