    Exaust y pipe?

    I want my exaust louder & to flow easier it goes from a single pipe into the muffler then out of the muffler into dual exaust if I cut out the muffler how would I go about just straight piping it? Would I use a y pipe to bolt on the the single pipe? then pipe the dual exaust and just add some custom mounts

    Kooks now makes a gorgeous true dual setup for our cars, but it requires the use of a couple aftermarket suspension pieces to work and isn't exactly cheap. A nice option is an aftermarket catback system with an electric cutout installed in the mid-pipe. You'll get enhanced exhaust flow and great sound that you can tweak to your liking as you drive.

    Skip all that and just put a cutout in the I pipe before the axle under the passenger seat. It'll be louder than strait pipes out the back any way as it's closer to the engine and resonates under the car. Cheaper to boot.
