03 vs 04 Indmar exhaust differences?

[stennes]

I was looking at a pictue of a 03 X30 MCX and a 04 X30 MCX and the exhaust manifolds appear to e different, 03 is a 2 piece and the 04 a one piece?
03

04

03 is a 2 peice cast iron manifold and riser.

04 is a cast aluminum (I believe) 1 piece design that was substantially lighter than the 2 piece version.

So then the 04 is a better design? Would it replace my 03's?

I wouldn't bother. I doubt there's much if any hp difference and lighter weight really isn't what you're looking for in a wakeboard boat, is it?

Yes and Yes.

Why upgrade, though? Are your manifolds and risers already rusted and worn?

No but they need work, check my other post about the melt down, I have pictures there.

The upgrade to the 1 piece tuned exhaust manifolds does make a difference in
power and performance. It is an expensive upgrade. We have done that upgrade
on a LT-1 and also a 2003 MCX like yours.

If you did overheat your motor I dought that any damage was done to the manifolds
Clean and repaint. I can see that you need NEW hoses and probably mufflers

Isnt the muffler the one piece fiberglass tube behind the engine? If so it looks ok, What was the cost if you happen to remember?

Take a look at the cost difference...
'04 manifold: http://mymastercraft.com/product_det...oduct=Hardware
'03 manifold: http://mymastercraft.com/product_det...oduct=Hardware
Riser: http://mymastercraft.com/product_det...oduct=Hardware

Remember to multiply by two!
Not even close to worth it IMHO...

What would you recommend for the presumably ruined Silentmaster, Mike? Replace it with another Silentmaster, or switch to inline mufflers or baffled tips?
