    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) Click here to enlarge
    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? Click here to enlarge
    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. Click here to enlarge
    I took her for a ride when the installation was done, and WOW what a beast she became! Click here to enlarge

    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? Click here to enlarge

    Quite the price difference compared to the "mainstream" options.

    Where did you buy this IC from?

    I think he is saying the install is similar to AA.

    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

    Sorry but that R&D BS is nice euphemism for BMW tax...

    Great job on the IC bro! Looks sick.

    thats the same thing people said about the $200 downpipes and now people are finding out theyre rusting on the inside..btw the same argument can be made on the other side of the spectrum..aftermarket exhausts cost alot but the stock exhaust with no cats still seem to be the best option for the N54, most of the most powerful N54's are still running stock piping..its all about the R&D

    Will try to do some logs this weekend.
    Biggest difference is that the car feels crazy strong @ higher RPM's compared to my crappy RaceCooling IC I had on the car before. Click here to enlarge

    Ding Ding Ding, It sad what some of these companies charge, hell some dont even offer piping and other offer like 1-2 feet of piping on each side. Other cars which have turbos mounted near the firewal and require custom intakes/charge pipes/hot sides/cold sides/go for less. And the cores are legit. Look at the 135 axle back exhaust. Some companies have the balls to charge 700-800 for straight pipe that delete the muffler? REALLY?

    Great job with the FMIC

    Alot of people who've bought the VKs are happy with them. I almost went with them myself because I refused to fork over 700 dollars to AR Design. I haven't heard of the VK's rusting, Raceland yes but they've fixed the problem. $350 for pipes or $700 for pipes. You wanna pay more for piping be my guest, they both do the job. The problem vendors in the BMW community know that you guy will fork over the cash without any complaints about the ridiculous price, so they continue to charge whatever they want.

    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.
