It sounds like it could be true if you are running 750 HP with stock exhaust?

I do not know I was guessing?

do you think basically any muffler like magnaflow will increase hp as you increase hp in the engine?

More air in more air out thats the physics for more HP.

I think you could see that much gain if you have true duals at least 3 inch pipe, good headers, and a built engine. You just have to have enought air coming in to make up for all the air needing to get out.

dude, get either a magnaflow exhaust or an slp loudmouth / catback, and be done with it, there like 250-450

i know im planning on getting the magnaflow, nice heads, headers, cams, rockers, and some other stuff, that will add up to $3k to make mine 500-550hp all next year(i hope)
