We recommend 3 heat cycles as a break-in period before really getting on the car hard. This can be found in the installation instructions..

Thank you, Blake

Tony recommends to do 3 cycles of start car, let warm up to operating temperature, turn off and let cool down. All this before driving the car with the new exhaust.

Edit-Blake beat me to it :tup:

:iagree: Sometimes based on their positioning between the axels and excessive diameter compared to the actual piping, these will actually scrape on speed bumps before any other part will. :ugh2:

The flex pipes give more room to adjust for the fitment, but when the car moves all the moving force is applied to the flex pipes thus it's easy to sag and broken after the time. I think Tony explained this somewhere. Just can't find it now.

I'm halfway through my waiting period! It's just like quitting cigarettes, the first couple weeks are the hardest but you KNOW it will be worth it.

Oh Woops I saw "waiting period" but was thinking shipping window. I'm 747, I think my shipping window is around end of June into first week of July. Hopefully I can get it on for 4th of July:tup:
*edit: it's 6/27-7/11

Really? Proof of this? Seems to me like it would take off stress of things. Yes the CBE is supported by rubber hangers so it can move but to me it still seems like major stress at the header to head location. Probably why race applications require your to safety wire those nuts.

Hmm ill have to find that. Makes no sence to me at the moment.

Read any of the dozens of FI customer reviews. This exhaust is constantly complimented on it's ease of install and borderline Better than OEM fitment. Tony and his crew did an outstanding job making sure you could literally pull this out of the box having little or no technical expertise at all, and install it with Zero problems.


Flex pipes account for vibrations, and motions from the engine/header/cbe, yes. However, typically they are not made from the same grade of steel as the rest of the exhaust, so they will rust out. 2ndly, they are typically lower at their point under the body than the rest of the system so they have a potential to scrape easier. 3rdly, a lot of companies use them so that their system doesn't quite have to fit exactly right, there is room for error. Tony doesn't operate like this, nor should anyone else. You make it fit, or you scrap it and start over.

Question about exhaust without flex pipe - G35Driver
So they're willing to install a part they know will eventually fail? Over installing a part that could possibly fail??


:ugh2:

I've got one of the earlier systems, LTHs + CBE. I have zero cracks, leaks, or noticed any weakening of the system. 3 years and counting.

Install and fitment don't worry me though, longevity does of other parts or weld joints. From what I read I have to disagree with everything you said respectfully. The MXP CBE for example I guarantee doesn't scrape nor any other CBE system I ever had like Turbo XS or Invidia. Also I don't think companies would sell $1000+ CBE and use mild steel flex pipes. I just checked my TXS flex section and its 304SS as my neodymium magnet will not stick. A google search also comes up with no flex sections that aren't 304SS braided. Now the end caps might be 409SS but that will still out last the car. One last thing, if the flex sections scraped than so would mufflers and resonators as they are much thicker in diameter than any flex pipe. The flex pipes are bolted right buy the cats which will not move that much. Ever flexed a flex pipe? You get maybe 1/2" in trying to move them. No where near enough to touch the ground unless a company has the pipe hanging to low.

How? This is 50'000 miles, 3 harsh ohio winters, 300 plus HP, almost 400 TQ from a turbo so much hotter gas, and besides surface rust on the pipe that happens in ohio which you can see comes right off where I polished it, it looks beautiful with no leaks. You saying a flex pipe will fail eventually is the same as me saying your header will crack and leak since it has no flex pipe in the system and since the header isn't made of 321SS. Anything could happen but from my racing experience you need a flex pipe on big motor high HP applications. You might be ok though since these motors have no TQ!

JC671 05-31-2013 07:59 PM
Synolimit if that is what your use to and feel comfortable (having a flex pipe) for your ease of mind then by all means go buy an exhaust or header that has one. After Chris explained the reason behind F.I. part of not having one and the countless of reviews and support. If you still don't like the answer or the exhaust then look elsewhere.

As far as your TQ comment, I'm guess your basing your opinion because or your two WRX's you have. That is a bad comparison. You are comparing a turboed boxer engine vs a N/A V6. Not exactly the closest thing to compare to.

Please save your opinions war for PMs and if you have further questions I suggest calling F.I. directly.:tup:

So I just wanted to chime in on this one a little bit. Believe it or not, I have been asked this question many times over the past 9 years ever since we started making exhaust systems for the 350Z/G35 Coupe. Here is why we do not use "Flex Joints" within our 2.5" cat back exhaust system. Please try and keep an open mind when reading my reasons because some of them are facts a few are opinions and some of them are based off of experiences.

-Flex joints are designed to give you more adjustability in the exhaust fitment, yes. However they are there to soak up in consistency in slight alignment issues. If an exhaust system is not produced to the exact spec of what it is bolting up to, the flex joint will allow you to fudge it and make it fit. This is not the correct way to do things. Sure it will take the bind off of the exhaust system and in turn shift the bind into the flex joint.

-In the case of this specific car the first rubber hangers that hold the exhaust up are located right in front of the rear sway bar. That is physically far away from either the transmission brace on the catalytic converters or the head of the engine. Now if you put flex joints directly in the front of the exhaust system everything behind them will (weigh) on them. This puts a lot of stress on them and after time they will deteriorate and eventually sag or worse yet, blow out and create an exhaust leak.

-They will decrease ground clearance.

-They add material cost and production time to the build process.

-The list goes on and on but in the grand scheme of things, your engine sits in rubber motor mounts. Your exhaust system sits in rubber hangers. Your exhaust system is indirectly bolted to your engine through your cats and manifolds. Nothing is solid mounted to the car and as the engine torques, the exhaust torques with it.

Thats all I have for now. Thank you for your time.

This is the same guy who bought a Top Speed exhaust... Just sayin.

Baer383 05-31-2013 08:48 PM
I think it is funny as hell to see people come on this fourm and want to (or already know how) reinvent the wheel,and think they know more than the manufacturer that made the exhaust. :shakes head:

Ill add one. I see their answer, I disagree as I stated with everything I've said like ground clearance so we can leave it at that. I just wanted an answer and I got theirs so end of story.

All manufactures of cars that pay millions and millions of dollars into R&D use donut gaskets, flex pipes or both so its not me reinventing the wheel! It's FI doing something different so pardon my questioning when I see something out of the major norm!

You shouldn't question an exhaust company on how they do something when they have sold about 800 sets of this CBE and a waiting list 3-5 months ,also use sets of these go for like 1000 bucks used.

I would either get inline and wait,or I don't know go with Topspeed.:eek:

Well you sure did have a hard on for it.
http://www.the370z.com/intake-exhaus...-question.html

And FYI, I didn't ship that box, I coordinated the sale. Next time try and be accurate about the dirt you try to dig up and throw. You don't even know the full story behind it to comment. You plan on buying this instead and using a HFC as a muffler and attach it to the X pipe now? Wait, you are gonna tear it apart and add flex joints.

Huck 06-01-2013 10:07 AM
As I've said before, now that I have my FI swag if I had to buy another system I'd be willing to wait 6 months if I had to. I've helped friends install a couple other brands of exhausts on 370's and G's and this is still BY FAR the best exhaust I've ever come into contact with. It's well worth the wait, have some patience :) :tup:

quick question for others - any feedback on others experiences with FI test pipes/LTH/HFC's in combination with their FI exhaust? i'm looking for things along the lines of eg: "got HFC's wish i got headers" or "got test pipes, but wish i got HFC's because of the smell", or "got headers but i feel like it's a little loud for daily driving"

I'm looking to pair it with the FI 18" SS setup and I've debated the HFC/TEST PIPE/LTH question for soooo long now so hopefully others can chime to make me finally make a decision!
