    GruppeM Intake VS. Dinan Intake

    Here's the deal - I'm scheduled to get the Dinan S2 package installed soon, including the intake, etc. My plan is to use the Eisenmann exhaust and to keep the rest Dinan. But I keep hearing about this GruppeM intake. Does anyone have any experience and/or facts about using the Eisenmann exhaust/GruppeM intake/Dinan S2? Any compatibility issues?

    My goal is to get the best performance without sacrificing warranty/serviceability. Any feedback would be much appreciated.

    TIA

    If you are willing to spend the $ for the complete

    Dinan package then its definitly worth it IMO. If you lease your vehicle or dont plan on owning it for a long period of time then gruppem eisenmann is a great alternative. <hr>

    Can you elaborate?

    Why do you say that?

    Any idea what the HP/Torque gains are? Differences, etc?

    Thanks,
    CM

    HP gain from intake is supposed to be 14+

    plus exhaust = possibly 25 total? not sure exactly but its a noticeable difference (both sound and performance). The gruppem/eisenmann race combo roars at high speeds and is as quiet as a mouse at idle. If you are concerned with warranty and dont mind spending an extra g or so i would go with the dinan. They are both great products and you wont make a mistake either way. Remember i didnt want to add software and wanted to be able to simply unbolt after my lease.<hr>

    Back to the original topic :-)

    Based upon my experience with the X5, other BMW's and feedback from other X5 owners, in my opinion, the various CAI's and aftermarket exhausts rarely add much noticeable HP. Various tuners may claim HP increases from 8-20 HP but often time those numbers aren't realistic. Often times, a decrease in HP may even occur. Looking at the best case scenario, if the HP gains are there, they are usually at the very "top" end, not where you can really benefit from these mods. Most of the time these gains are accomplished by sacrificing both low to mid HP and torque. A complete "S2" package from Dinan that includes not only a CAI and exhaust, but also software, high flow throttle body and MAF is more likely to give you more positive HP gains but that too does so by sacrificing low end HP and torque. If you do a lot of city driving, you need that bottom end HP and torque to get you around. If you do the CAI and exhaust mods don't expect a whole lot of HP gain but on the flip side the sound of the CAI and exhaust will be awesome! I'm not trying to dissuade anyone from doing these mods but rather giving my "real world" experince with some of these mods I have experienced myself. IMHO
