    01 VLX muffler delete

    • Year: Choose Below Brand: Malibu Model / Trim: VLX Cost: $0-$249 DIY or Professional Install: I installed it Manufacturer(s) of installed products: Summit racing Platform Type: Teak Engine Type: 335 monsoon

    With surfing becoming the main priority on my boat I've slowly started updating over this spring. Numerous projects going on at once but the exhaust was a quick and easy after looking at a few similar projects here on the forum. I took a slightly different path from the last few I've seen for a muffler bypass. Instead of using straight rubber wet exhaust hose or even abs pipe I chose to buy 2 pre bent 3.5 mandrel 90° exhaust fittings from summit racing. I believe the part number was SUM-622130. I trimmed roughly 6 and 3/4's of an inch off of each side to make them slip into the existing rubber boots that went to the original silent rider exhaust. I felt like it gave a more complete finish to the engine compartment, rather than going with any of the alternatives. Once I finish the rest of the updates inside the boat I will be building my own fae from the same stainless exhaust piping.

    Nice upgrade.    What a clean solution as well....  It really opens up back there.    Can't wait to see the exhaust FAE project if you go that route.     When I did mine I used Burns Stainless, he had quality stainless, a little pricier, but gave a small discount for wake garage members.  There's a good number of stainless mandrel suppliers now.     Great project thanks for sharing

    Thanks for the tip on finding another supplier for the stainless Rugger! Your own projects are inspiring as well. The fae is probley another month out or so. Still have to get all of the interior back together soon... I'll post up the rest of the projects once its finally finished

    So the existing rubber boots fit onto the stainless 90? 

    Looks to be the case.  ie A 3.5” marine hose will fit over a 3.5” stainless mandrel.  The stainless pre bent mandrels are O.D. measured

    I didn't really word it correctly.

    I was wondering if he had to add a rubber hose or was the existing rubber hose and hardware sufficient lengths and angles so all he had to purchase was just the 90's.

    I used the existing rubber hoses and hardware from my factory silent rider muffler and everything fit great. Just took a little trial and error on cutting the stainless to fit
