Help with Factory Pipe exhaust

[SeaDooRider1]

Got this 2000 challenger twin 717 last year, I noticed it had aftermarket exhausts. I hear they can be complicated, I have both engines rebuilt and all are holding 150psi with about 3 hours on them. Is it worth keeping this exhaust or should I go back to stock exhaust? With what I’ve read about these Factory Pipe set ups is they require fine tuning and what not. Even as much as changing the carburetor all together for better reliability. What should I do? Keep them? Or go back to stock since I don’t have much experience to own these bad boys

Absolutely go back to stock. You don't want a Factory Pipe on a jetboat and the 720 ones are known to destroy engines.

Loud and clear. Thanks man, so basically I need the entire set up from water box to exhaust manifold, right? I’m gonna throw these up for sale. Where can I post them for sale here, what thread?

You don't need a stock waterbox but it will be much quieter than an aftermarket one.

Another question, I plan on buying stock exhaust before I sell these, can I use these in the mean time? If I disconnect the solenoid would it function similar to a stock exhaust, with out all that electronic mumbo jumbo

No, absolutely not.

Here’s what’s on the boat right now, I already posted them for sale on the proper thread

I also see you have SBT engines. You definitely don’t want Factory pipes on those.

You also don’t have the carb to head braces on, without them you will crack the intake manifolds.
