I have to run a stock exhaust in my Factory Stock class. I am running Vortech heads and a cast iron intake

Which stock exhaust flows best? looking to make sure everything breaths good.

Thanks,

Vortec manifolds are supposed to flow well,the old 2.5 outlet ram horns also are very good.

Did some searching, are the corvette style better than the vortech ones? I probably can get the vortechs alot cheaper. The only reason I'd use the vette ones is if it showed significant gains over all others since they are kinda pricey for my budget.

They are supposed to be the best(corvette ram horns)BUT they don't fit most frames very well,we used to cut them off and angle them back but that seemed to be too close to the spark plug boot,unless you can move the motor way back i'd use the vortecs.

I believe I seen some Vortec exhaust manifolds for sale on ebay the other day. Might do a search there and see if they're still around.
