Is the concensus now that the non-resonated F.I. CBE goes best with the LTH's? I'm thinking of swapping my 18" res x-pipe out for a non-res one. I'm looking for more of a rumble and scream (similar to the motordyne exhaust) and am wondering if going non-res would help. Any suggestions would be greatly appreciated :tup:

Just installed my new/used FI CBE today. Non-resonated sounds real good. Now maybe I can hear the car with the radio turned up.

I would think test pipes and non res would be more of a screamer. Headers are deeper sounding than test pipes, non res is def higher pitched than 18"

Has anyone seen a really good comparison video between the no resonator, 12" and 18"? I am trying to pick between the three and having a hard time deciding. Another issue is that each video is recorded with different volumes in place so it is hard to compare. Ideally I want something that sounds sexy, minimal drone, and will not attract too much attention in a work parking lot.

Gen 3 install will be end of this month, going for FI exhaust(12 weeks?), and then Berk HFC. Possibly a tune after that. Sticky tires and then I'm all done with the car.

I had that set up originally and yes it's a screamer. you are also correct with the LTHs giving a deeper tone overall to the system.

think of the NR, 12, and 18 like this: drone, less drone, least drone.

the volume difference between NR and the 12/18 is louder and the 12/18 res have minimal volume differences between them.

EYE ESS,

Hopefully I can offer some words of wisdom in making your decision easier.

Our Non-Resonated exhaust is our loudest option. It is very exotic sounding and slightly higher pitched. With stock or high flow cats rasp will be very minimal; if any at all.

Our 12" Resonated exhaust is our middle of the road option in terms of sound level. The 12" resonators will smooth out the exhaust note and quiet down the interior noise.

Our 18" Resonated exhaust is our quietest option. This resonator option will cut the most interior noise out as well as give you the smoothest exhaust note. Even though this is our quietest option, it is still a large improvement over the stock exhaust note.

NOTE: The resonators are strictly noise canceling devices and DO NOT hinder the performance of the exhaust system.

I hope this helps, and if you have any other questions please feel free to ask me. :tiphat:

Will you be selling your exhaust then?

Well i posted in another thread, But since its all about FI here, and the presence of FI here will maybe clear my doubts

Ordered FI CBE 18" Resonated With RHFC

The RHFC has options such as Extra o2 Bung
Description States - Optional extra wideband bungs can be welded in either one pipe or both pipes for an additional charge. A wideband bund is generally used for A/F ratio's on a dyno or an actual A/F wideband gauge within the car.

Do i need this ?
Also, Resonated Test Pipes VS Resonated HFC's ? DO i need these o2 bungs ?

I thought picking the company would be the hard part :P But fast intentions managed to put so many options, Life has become hard

I am going down the TT route And Kevin from FI confirmed that the HFC's will be implemented in their TT setup.

No, if I decide to go the non-res route, I would just purchase a non-res X-pipe and swap it out...thats another great thing about the F.I. set-up.

Thank you fast intentions.
I have received my exhaust and installed it over the weekend. Looks and sounds amazing! Too many thumbs up to count when on my daily commutes. :tup: :tiphat:

Thanks Kevin! I have the perfect question, since I had the Stillen exhaust I know the note very well. Would the non resonator or 12" resonator be the closest in terms of overall volume? The Stillen was the one I could get away with and not attract too much attention. I don't want to go much louder.

I think the Stillen would be equal and possibly a touch quieter then 18".

If you are concerned with not wanting to attract too much attention I would recommend our 18" resonated exhaust system with polished stainless mufflers. This exhaust option will produce a deep, smooth exhaust note that is still noticeable improvement over the stock exhaust. I had an 18" resonated exhaust system on my own car.

i have the 18" resonated CBE and it is louder than stock, minimal cabin noise (noticable in cabin noise at 2-2300 rpm), and sounds great WOT! i recently installed the RTP and it sounds even better! deeper tone, not much increase in cabin noise during cruising (even on highways at +70 mph), but loud w/cold starts...

Glad to hear, as this is the exact same set-up I have in my basement. Just waiting on my friend's mechanic to have some free time!

About an hr install. No need for a mechanic

I agree. They send you step by step instructions that are decently detailed. From the cats back,it literally took me longer to jack my car up and put it on blocks(no hoist :shakes head:)than to do the exhaust! The cats are a different story. I'm about to go and do them today. Just got to go and get me some extensions and an O2 sensor socket. :tiphat:

I found this on the interweb... Paying for someone to install this is kind of a waste of $$ It's SOOO EASY!!!! Even if you don';t have the tool, go buy them and do it! That way, you have tool to do other thing to your car. There was another video I found way way back where a guy installed it on a lift so the video came out really clear and nice. I just can't find it.

I tried to install it myself but I could not remove a few bolts. I bought a craftsman 1/2" 400tq impact wrench with 6 point impact deep sockets, jack stands, low profile jack, creeper... I spent close to $400 on tools... I ended up return it all and taking it to a shop. I spent about $300 for the exhaust and test pipes installation (at different times) I'm sure it would have been cheaper if I had it installed all at once. If you don't want to stress out about stripping bolts and time spent on the install I would recommend taking it to a shop... I dropped it off in the morning and picked it up during lunch... stress free :)

Define stress free? Lol, you have to work for that money... I know being in the Navy is not stress free! Cash isn't very abundant either. Makes me wonder if you were tugging on the welded bolts from the stock system.. My Nismo exhaust had them anyways...

Stress free = no worries... Being in the Navy can be stressful at times but you get to that point in your life where you have to weigh your options... I tried buying the tools to do it myself at home... did not work... I was not going to spend $800 on air tools... I tried taking it to the hobby shop but the wait was insane... at least three hours for a bay... so why stress about money and time when I can drop it off at a reliable shop. it was cheaper than buying the tools and it was faster than waiting on a bay at the hobby shop... stress free :)

Taking those factory cat bolts out ain't for the faint of heart! I'm 6' 3" 210 lbs and I had a bitch of a time with those bolts. two feet of extensions and a snipe with some wd 40 and I spent about an hour and a half bustin them loose. Not to mention a few scrapes and battered knuckles. Also had to change my ginch when I got home! :tup:

I know pulling wrenches aren't for some people. As for myself,I like to be able to say I've done some work to the car myself.

The cat nut's aren't too bad. I got mine with a long snap-on box end 14mm wrench. A shot of PB-Blaster with some tail behind the wrench. LOL Snap-on hand tools feel good to the hands when dealing with stubborn bolts if you have to go manual.

I got all the way to the cat bolts today and they wouldn't budge. I just had test pipes installed 5000 miles ago I'm suprised they're so tight. Maybe it's time for an impact tool..

Placed order for Non Res CF 2 Days ago....Ship Date Approximation is end of June...:eekdance:

My impatience is getting to me already...2 days in..:icon17:

Thanks again for your business and your support! It will be well worth the wait. :tup:

I did install my CAI, LED, HID 6K bulbs, and LED halo eyes ;) just couldn't get those darn bolts loose...

I bought the Craftsman impact wrench (1/2" cordless and wired 350-400 tq) around $200-300... it's okay... It did not loosen the exhaust bolts at all... but you will spend a lot of money on the air impact tools... at least $800 for the compressor and a decent impact wrench...

I attached a vise grip to my 3/8 drive ratchet lol I got them all off. one more heat cycle and I'm going to go for a drive :tiphat:

Post a Video if you can. Let's hear how she sounds!

:driving:

I'm definitely going to make a video. Right now I have berk test pipes on, but soon I'm going to install fast intentions long tube headers

There should be a thread made dedicated to just Vids/Clips of the FI Exhaust/Cats/ & Combos. So that each type of Resonator Option + Any additional HFC/TP/Header is covered so that everyone know's what they can expect.

just my .02$..I'll def be doing a before and after when I get my exhaust..end of june...:(

You can be a creator of such a thread.

I should..I just dont want to use someone's youtube video without their permissions. But as soon as I get my exhaust I am def. going to make it. :D

why not use it? it was posted on Youtube to viewed ;) if not the owner can always take it down

I just had my FI catback w/18" resonators installed in a local shop yesterday. I told the guy to read and follow the instructions, and charge me for the time it takes. It took him 90 minutes and he charged me $100. He also said that it was maybe the best aftermarket exhaust he had ever installed in terms of quality and fitment. I sent a picture to Kevin at FI and he said it looked like a perfect fit. I'll DIY when I don't trust someone else to do something, otherwise I'll happily pay $100 not to have to crawl under a car.

BTW, it sounds awesome. Louder than I thought, even with 18' resonators, but in a pretty good way. The OEM stock exhaust sounded like an angry vaccuum cleaner IMO. Now it sounds like a beast.

Same here. I wish I could have mine on before Zdayz. Would love to go with a not stock Z!

wait until you install the resonated test pipe... man, what a growl
