    which free flow exhaust? riva vs R&D? SHO

    hey guys,

    i have two 2009 SHO's, but want an exhaust for one of them to make it sound a little bit tougher and maybe a slight perofmrance gain. However, the riva and R&D look completely different, so im not sure which one to go with (dont want through hull though).

    the ski has a riva air intake and HKS BOV, so just the basic exhaust upgrade will suffice.

    Also i have noticed the hull rear step platform tends to flex in when accelerating, so would adding vents to the body help it to breath.

    thanks guys

    Riva


    R&D

    the hardest part was getting the oem crap out. the riva kit leaves you more room in there than the r&d kit.
    also, the r&d kit was on back order when i did that upgrade.
