Fast Intentions exhaust is here! (continued)

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.

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.


Edit, quick google turned this up first. Seems I'm not alone

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.

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.

So they're willing to install a part they know will eventually fail? Over installing a part that could possibly fail??




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.

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!

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.

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
*edit: it's 6/27-7/11
