I thought about it, but after talking with my neighbor who owns a plumbing company, he thought it was too much heat. But if Carlsonwa has it and it hasn't melted or deformed....COOL. Another cheap fix that works. I'm just runnin 3" hose to 4" exit

Had a 04 X2 and it was a pita to sevice the impellar so I removed the silent master and replaced it with pvc pipe and angles
BTW my silent master is for sale $100 + shipping

Well after searching for parts online I've concluded 2 things.
1. I wont be using PVC. Replacement parts aren't too bad.
2. There is A LOT of restriction on these systems.
The risers and fiberglass silencers have a ****-ton of exhaust flow obstacles and deflections. Wish I could get a decent pic for show and tell. One would think there is a fair amount of performance enhancement there. I'm wondering tho..what kind of back pressure, if any is needed?

I know exactly what your talkin about inside those mufflers. I was pretty shocked to see that as well. As far as back pressure.....who knows. My boat has been "open" for 4 years now with no probs. Power seems plentiful. Just my opinion.

I have this exact problem with our 2005 X7. just discovered it tonight. originally thought it was where the drive shaft goes through the hull. I have some extra fiberglass lying around and will try this repair tomorrow. how many layers are needed?
