Food for thought here an aluminum manifold and aluminum riser exhaust system for nearly a $1000.00 seems like a lot of money??

While your choices are endless. If affordability is your concern you should look at the "Super Sport" series systems as they are a great value they feature internally divided runners as the systems referenced here do and they have a polished stainless steel exhaust riser for only $1175.00 http://www.cpperformance.com/detail.aspx?ID=6941
The same system is available with a aluminum riser for $579.00 http://www.cpperformance.com/detail.aspx?ID=6943.

Stainless marine builds the longest lasting best built system period. It features an internal header casting with draw formed water jackets around the outside. In the event years from now it may fail it will fail externally, and not internally into the engine. These systems sell for $1682.99 http://www.cpperformance.com/detail.aspx?ID=2906

In the end I would have to say the number one performing manifold sysem for a small block chevy by shear power numbers is still the Imco Power Flow. This sytem has the longest best seperated runner design of any current small block exhaust manifold. This system sells for $1975.00 http://www.cpperformance.com/detail.aspx?ID=2644

This is just a fraction of the systems we offer. Another thing to consider we don't sell brackets and accessories separately as they are "ALL" included. lets face it you probably need them? There's no reason to tell you your exhaust costs $XX.XX and oh yeah you need to buy more stuff? Let me know if we can assist you. Happy Boating
