    Exhaust delette

    Hey quick question. I was thinking about running straight pipes from the cat instead of doing an exhaust system. My only fear is that I won't have enough back pressure and it may lose torque and horsepower. I've got a 2014 WRX. I'm thinking because of the turbo, back pressure loss may be minimal to none. What do you guys think I should do?

    "From the cat", meaning post - cat correct?

    What diameter piping?

    All you'd accomplish is having a pretty loud car, I don't see how you'd lose power. Most aftermarket catback systems are 'straight pipe' setups anyway.

    You won't lose power, you want maximum exhaust flow behind the turbo.

    That will get you an extremely loud car. Make certain that's what you want.

    I'm thinking three and a half inch piping that turns into a 4 inch exhaust tip
