Thread: PVC freeflow?

    PVC freeflow?

    I've seen several pics and how to's but could someone tell me what size pvc is needed to fit in the stock rubber hose?

    The reason I ask questions like this is because I live 35 miles from the closest real store. So when I start a project I like to have everything I need. Thanks guys.

    3.5 Inch OD (Outside Diameter) for the two hoses to slide over perfectly.

    Yep, what Abbott said. It's just PVC sewer pipe from Home Depot.

    Definite minus is the louder exhaust. I had to coat my waterbox with a thick layer of spray-on bed liner to cut down on the sound. Next time you have your waterbox out, set it on the bench and tap it with a screwdriver - and listen to how loud it rings. The FF just makes it worse. I actually wear ear plugs when I ride now - but I have bad hearing and try to protect it.

    Here's a pic of my str8 exhaust dude. I used a 45 deg. 3.5 inch PVC pipe from Home Depot. Just installed & launched. No cutting or drilling. I used my stock hoses. It's great. I know that for the GPR it's a bit different but the same strategy can be used. Look around the forums. I've seen them done the same way. If u live far from a good hardware store then just buy plenty of PVC in different angles & buy straight PVC pipe too. U want to spare pipes rather than run out of pipes.
