Thanks..

Your manifolds & risers arrived on friday.. Bling bling! The tips are still on the way..

Btw: I believe I said labor to install the manifolds is a minimum of 3-4 hrs depending on application, not including the tips..
The Cmi system takes even more time to do due to line mods & other relocations..

How do you get 40-50 more horsepower from an engine that uses a speed-density fuel injection system? Are you having the computer reprogrammed, and, if so, how do you reprogram the computer?

I have been doing some light research on the 496 exhaust as well. Some things I have been told are the fact that without changing internals or adding an "air maker", the exhaust is where the horsepower gains are. CMI has dyno sheets showing 50 HP. The gains are produced by the scavenging effect of the long primary tube header. I guess EMI and the like (aluminum manifold similar to stock) produce some HP but less than headers. I haven't seen any actual dyno sheets. It is also my understanding that the results from adding exhaust shown on the 454/502's mean nothing on the 496 platform. And I get the impression from reading Raylar's comments that the stock exhaust isn't that bad and the improvements from aftermarket is minimal without making the motor flow more air from changing cam, heads, etc.

So what do us "frugal" guys do to gain around 50 hp?

Anyone with a crystal ball or money tree?
