    Are straight pipes allowed in DSP?

    :?: :?: Per what I read it seems yes, I just need an affirmation as I budget for the future...

    Exhaust manifolds and muffler systems are free, except that they must be quiet and terminate behind the driver. Exhaust heat shields may be removed. Rear- and mid-engined cars without exhaust headers/manifold systems may use any exhaust system that meets the requirements of 3.5. This permits the removal of "heater boxes" in order to install headers on such cars.
    I know they said they must be quiet, by comparison my car is not LOUD but its def. louder than stock

    If it says they are free, then they are free. And quiet is a relative term anyway. You're gravy.
