    Re: Cargraphics R-Exhaust system

    Re: Cargraphics R-Exhaust system

    I confirmed my order this morning and will collect and install the exhaust next friday.Of course I'll keep you all updated...

    Re: Cargraphics R-Exhaust system

    Luigi,

    soon as you have your exhaust please make a record of the sound i'm wondering how it is.

    Regards Bruno

    Re: Cargraphics R-Exhaust system

    Ordered the EP today, but won't be here in time for the dyno day at AWE 12/22. I may wait to install it when we have some decent weather for me to make the trip to install it at AWE and run a dyno before and after the cat/muffler swap. Stef at EP is very helpful and provided these responses to some of the questions I had asked him...

    1) Our 100 cell race cats will not cause a Check Engine Light problem .
    We had the original 300 cell GT3 cats chemically analysed . According to this chemical analysis our cats are specially coated for street use . The chemical coating is superior to the coating of regular race cats .
    The US GT3 engine is identical to the European GT3 counterpart in terms of Lambda / O2 sensor setup .
    You do not need an ECU reprogramming with the new exhaust .
    However , an ECU reprogramming will indeed maximize the performance of the exhaust system .

    2) The dyno graphs are from 1) stock engine , 2) stock engine with the new
    exhaust , stock (not reprogrammed) ECU and stock aircleaner .

    Dyno stock pipe: 385.1 PS (Hp)
    383 NM Torque

    Dyno europipe: 397.7 PS (Hp)
    394 NM Torque

    In summary: +12 HP, +8 lbs/feet torque

    At the wheels before(stock): 278 (PS) Hp
    At the wheels after EP: 304 (PS) Hp

    That's +26 at the wheels!!! Not to mention the awesome note...

    Here's how it looks installed on their demo car in their spotless shop...
