I just received my Hallman Pro Boost controller and I read the directions that came with it. It says to not install it unless you have "a performance exhaust system".

I'm pretty sure its safe to install the mbc and run stock boost (which is what i intend to do) with the stock evo exhaust but I just want to double check. Should I wait until I get my full tbe (which is on the way)?

I have a stock 04 evo 8
