hmm... i dont know still leaning towards an HFC tho.

seems like FI is winning 100% here. but i still need to research and see if anyone is having CEL problems! many of the threads are out-dated about this topic and i dont know if that CEL issue has been resolved with newer Gens of HFCs.

It's not an either/or. I was just pointing out that the $85 difference (which is off retail, not what a vendor can get you) may not be as dramatic when compared with the cost to get it installed.

i see your point! i am just sayin i am probably going to stick with the FIs (probably)

Absolutely get the cats. Just make sure you're done adding parts before you get tuned.

yah cats uprev tune and i am all set till my tires are worn out. but thank you for all your help much appreciated.


i am going to probably call FI for more info about the CEL issue. i will post it here anyway just in case someone down the line had a similar question.

If you're getting tuned, who cares about a CEL? That code will be turned off anyway.

The Non-resonated would be louder, but how much louder that I could not tell you. I would suggest that you call Tony at F.I. and ask him what the differnce in sound is. You will get the same hp either way. My exhaust is already extremely loud, but the RHFC gives it a deeper sexier sound in lower RPM's & at a cold start. The higher RMP's would just be insane. I wanted to make the sound even more exotic/sexier.

LOL touché. BUT!!! if i can get it without a code i will be one happy Z driver. :rolleyes:

Any of the HFCs with the "J" extended O2 bung shouldn't have any CEL issues.

lol you killing me!!! thats exactly how i want my car to sound not lound rather a tone to it!!! do you have any youtube videos up for your set up? i am curious and would love to hear what your set up has to offer!!!!

+1 rep for all your help and patience. Thank You

LOL..... No video yet. There was a guy that posted several videos of his G37S who has the Meisterschaft FCB, RHFC & Stillen Gen III. I believe his videos were on one of the Meisterschaft discussions. If you watch & listen to his videos, my car sounds EXACTLY the same as his.

I am going to get a tune this Sat., so I will have dynos before and after and it is also the Houston Z's Xmas party. I'm assuming someone there will have a video camera, so hopefully we can get a recording.

John_Kay you are comparing apples to oranges with the way Stillen FCB would sound with either Non-resonated HFC or RHFC vs. Meisterschaft FCB would sound with either Non-resonated HFC or RHFC. Meisterschaft FCB is A LOT louder than the Stillen FCB.

I would love to see the dyno charts along with a video when you go to the party. just hit me up or ill keep an eye.

as far as the comparison, i am not sure when i compared both!? i am happy with the stillen i do not like loud cars rather toned cars with deep sound. so not sure what you meant there.

I wouldn't wouldn't mind seeing what kind of numbers I can bring in. I have not seen any dynos done with the Meistershaft exhaust and as far as I know this might will be the first on the forms.

The link below was the topic of discussion and on the second page are the videos.

Thats soudns really good!!!!! damnnnn.... well i already have installed my stillen CBE. so i guess RHFC it is i dont want my car to be super loud (as i stressed few times).

and i am probably leaning towards FI since it adds the most gians, and also the poll speaks for itself.
