    Question How To Run Open Downpipe? Help!

    Hello Folks, I am pretty new to the subaru community. I currently own a 03 Bugeye & I just wanted to know the process of running on Open Downpipe. My Car is 100% stock with an HKS Hi Power Exhaust. I just wanted to hear how would it sound like if I run with an open downpipe. If so, whats the steps? & which part of the exhaust do I need to remove? thanks all!

    Dont do it, I did it when I went drag racing, left me with a headache afterwards and it felt like the car was going to shake itself apart.

    uhmm...Remove the catback, so that all you have is a downpipe... Put your head under the car so you can hear it better, then pound the gas pedal and enjoy. and you'll need to buy a new gasket for when you decide to put the catback back on.

    There are a couple bolts on the downpipe to midpipe flange. Remove those. Then there will be 3 rubber hangers. Remove those. Pull the thing off.

    It'll be loud, and raspy. You'll have less back pressure, so you run the risk of overboosting. Especially as the weather gets colder. Personally I wouldn't do it.
