Blaster Riva Red Pipe Install

[offroadenemy]

I am going to put a Riva Red Pipe on my 96 wb1. What tricks and tips do I need to know prior to intalling the pipe?

I have had the best result mounting the pipe while the motor is out of the ski. Make sure you shim the head bracket where it bolts to the pipe properly before you tighten everything down otherwise this can cause issues with the coupler bolts.

I've heard some red pipe owners prefer a stud kit for durability and ease of install. Next time mine falls off I will definitely be adding them.

The red pipe makes great power, the down fall as mentioned before is it will blowout is coupler gasket if it isnt setup with some extra care.

This is what we do and have had success.

#1 Make sure every bolt associated with the pipe and mounting assembly has red loctite on it.

#2 As mentioned above, make sure the shim the head to pipe bracket so as when you tighten it up it doesnt "pull down" any parts to mesh with the other surface. You want everything touching when its loose and just tighten it together.

#3 The exhaust manifold to chamber connection uses three bolts to hold it together. We swap those out for studs and then safety wire the studs so the nuts will not back off.

#4 The gasket for the exhaust manifold to chamber has very little machine surface to actually seal against do to a misalignment casting flaw. To get the most sealing possible, apply a 1/8" bead of black RTV silicone to both side of the gasket and let it setup for about 30minutes before assembly.


Also just a tip: Make sure all the water passages are clear and free before assembly. The pipe has a small fitting the top rear of the chamber that likes to get clogged. Its always good practice to have water filters installed on your boat.

The stock gasket on the red pipe is worthless. I cut a couple out of some heavy duty exhaust manifold gasket material. It has a thick sheet of metal sandwiched between think gasket paper. This stuff is so think you cut it with a sharpened flat screwdriver and a hammer.

Worked wonders to seal up a custom downpipe flange that was so warped it should have been cut off and rewelded.

Using the new gasket on the redpipe we just throw it back on and don't take as many precautions getting things perfect. Soon enough it will be gone in Lou of a bpipe.

How much is the stud kit and where can I get it from?

 

[BombThreat]

Just order a stainless threaded rod from Mcmaster carr and cut it to the needed length... They are cheap, under $10.

Instructions might help:

what size is are the studs, my local home depot doesnt carry much in the way of metric so I cant get a sizing for the studs.

Home depot no go. I never see a good stainless selection in lowes or home depot

Not sure if RIVA still carries them? U should be able to get them from your local dealer.
