Been wanting to free up the exhaust a bit without too much noise
has anybody tried this set up before!?
If so hows the sound!?
And does it rasp or drone!?
Thanks for any info

 

There were 4 orders for them with our last group buy to pair with OEM exhausts. The shipment should be in the mail by next week for those people to post up their reviews for you.

 

Getting mine installed tomorrow so I will let you know how it sounds. Excited to hear the sound. It is a daily driver too.

 

I DD a sedan with stock exhaust, and once its back from the dealer I will be installing my RHFC's so ill let you know
Basically, I was told that it will keep the stock note, but a bit louder. lets hope

 

I had the FI RHFC on OEM exhaust. There was zero rasp or drone. I recently purchase Invidia Q300 CBE and I'm thrilled. It's just loud enough for me to hear with the windows up but not loud enough to irritate the neighbors or cops.

 

Performance motor sports in St. James, NY (great guys) installed my FI RHFC on the stock exhaust. One issue is one of my O2 sensors was stuck no matter what was done. I had to get a new one. This was not cool but that's life. Apart from strong exhaust sent car sounds the same at idle. Things I noticed:
1. Slight vibration at idle but no rasp or drone
2. Loss of low end torque in D, DS and M modes. Car is noticeably sluggish in gears 1-3 but rockets off in 4-5 at higher RPM. My friend driving behind me noticed the lag. DS is the choice of driving now as it is better than D or M.
3. I only hear a difference in sound at acceleration over 50 mph.
4. ECU is learning the addition of FI RHFC
5. No CEL (day 2)
6. Will add a CBE in the future and do a tune to have the car run at its best.

 

I only know one person that did it but every time i see him i never seen him drive his car.

 

Did you have any other questions about the RHFCs? Otherwise we have a GB on the RHFCs as well as a first for catbacks! Be sure to check them out!

 

When are you thinking the catback group buy may be happening?

 

Here's a 2 week update on my Gigi:
- no CEL
- driving in all three modes are getting back to normal
- slight vibration when idling
- you can still hear VQ sound while accelerating regularly
- at 3K rpm car sounds a little high pitched idle sound. Just started hearing that .. Not too bad.
- at WOT, sounds awesome. I can hear the stillen Gen 3s screaming too.
So far, sounds good.

 

I ran this setup for about 2 months while waiting on my catback to arrive. Sounded great! Added a little bit of sound when you tromped on the gas. Around 2500-3000 there is a really nice throaty sound. During mild driving hard to tell that much was done. In the cabin with windows up most people that drove with me couldn't tell anything was done but going under a bridge (windows down) with the throttle down everyone said they noticed and liked it.

No drone/rasp at all with just the cats. I had stock exhaust rattle when cold which was apmlified by the addition of the cats.I didn't feel like I gained much from doing the cats alone, but as soon as I put the full FI catback on I got a nice boost in power. Was very noticeable. I'm loving my setup, cant go wrong with FI's.

 

Awesome, I'm installing my FI RHFC tomorrow and I'm thinking about the Q300 in the near future. Do you happen to have any sound clips of your setup?

 

Damn good info.. Deff. Gonna check out to group buy..

 

Just installed my FI HFC as well.

Installed last week and finished with a tune from UPREV. When paired with my ARK exhaust and Stillen Gen 3, I smile from ear to ear! Sound is clean with no noticeable rattles. Low end suffered some but great mid and top end power! This I can live with!
