Expansion Chamber rocksolid vs sickbikeparts

[atomichurley]

Hey Guys, i'm looking into getting an expansion chamber for my bike and the only two i have seen on the internet are the

Sick bike parts one:

Rock solid engines (yes i'm an aussie):
http://shop.rocksolidengines.com.au...ge=flypage.tpl&option=com_virtuemart&Itemid=1

How much power does an expansion chamber add and if anyone has has both of these chambers is the rock solid engines on worth the extra money?
Thanks

$240 for the Rock Solid vs $67 for the SBP..
That alone would answer any question I had. I can't see the RS pipe making $180 worth of more power. There is a 3rd pipe, the one I call a Banana pipe; http://www.gasbike.net/bike-motor-engine-expansion-chamber.html $60 shipped free, but I don't know about shipping to Aus. Plus King cycle and Sales(I think that's the name) has a pipe set up, too.

Performance-wise I have no idea about the best one is. I'd put my money on the SBP pipe.

The one at gasbike.net looks alot the same as the zoombicycles pipe. http://www.zoombicycles.com/eShop/Parts-and-Accessories/Aftermarket-Parts/bi-expipe-NEW-Expansion-Chamber-Exhaust-Muffler.html

Also I have the SBP pipe and it works and looks great. I'd recomend it, although I don't really know much about the others.

S.B.S. pipe

the one I got is from S.B.P. and it about doubled my horse power. the disadvantages are that your gas savings are less and the power band is a lot steeper.i had to modify my pipe so that it would not hit my crank or rear wheel. I will let you folks know how it worked out.

I'll sell my slightly used (less than 20 minutes of use) banana pipe to anyone interested for $40.00 shipped! It had great power but bothered the neighbors too much for me to keep it on.

Don't buy anything till you are sure about also getting a good silencer for it.
Expansion chambers are LOUD!
