Homemade FMIC (Even bigger than AA and HPF) for $300
Why buy one of those overpriced FMIC's out there for ~$1000 when you easily can build a bigger one for $300? (All hoses and pipes included)
The IC it self costs $240 and the pipes and silicone hoses costs $60 from a shop here in Sweden.
I like to do things by my self, so I said to my self; Why not give it a try?
This specific IC has an area of 13770 cm3.
As a comparsion, here's some of the most common and biggest FMIC's out there right now:
Helix: 11917 cm3
Stett: 11470 cm3
HPF: 13282 cm3
AA: 11085 cm3
The stock IC is: 7620 cm3.
The installation was quite easy. Just like the AA IC you just have to trim the stock IC-shroud away.
One thing that worried me a bit in the beginning was if the boost response maybe could suffer from this HUGE IC...? But, nope! She was still as fast and responsive @ WOT as before.
I took her for a ride when the installation was done, and WOW what a beast she became!
I will do some AIT-logs in a couple of days, but im shure that this IC will do an incredible good job.
I will also take some better pics of the IC, mounted on the car.
Could this be the biggest FMIC ever mounted on a N54?

Quite the price difference compared to the "mainstream" options.
Where did you buy this IC from?

Tom, where was the IC bought and where is the DIY? I'm looking forward to this as I may just do this myself!

Nice find..but I think size isnt the only thing that counts when designing a FMIC..alot of R&D goes into the Ic's from AA and HPF

For example AA's exhaust for the 135. A basic rear section with no mid pipes and a "sound cancellation chamber" for $700. Aahahahahahahaha $700 for a freakin muffler??? Now you have to ask yourself why would someone make a muffler and try to sell it for $700? Simple because they know people like yourself who buy into the R&D BS will line up to buy it no questions asked. Demand more for your money bro you work hard for it."I hate you, you, and especially you and hope that all the bad things in life happen to you and only you!"
