horsepower gain
 

What's an approximate horsepower gain from full exhaust ?( Flowtech headers and ORY with a Borla cat back) Does 40 horsepower sound about right, maybe less?

10 horsepower? thats pretty weak man im almost positive a header back gives you more than that

Try 20 HP +/- 5 HP depending on the system installed and the engine. My opinion, would be around 20 HP averarge with a good engine to start with. [sm=chattypair.gif]

If you redid the computer for them then 20 to 25, if not then 15 to 20....It depends on the cfm rate of the muffler. I think the borla mufflers are close to stock.
