your not gonna see much power and fmp isnt something you should hope on. everyone says an exhaust and headers benefits are Include Reduced Backpressure For Improved Acceleration And Towing Power, Cooler Underhood Temperatures, A Cleaner And More Efficient Burn In The Combustion Chambers, Better Fuel Economy, ect.

but all that is a bunch of s#!t. back pressure is the only thing affected and thats just the resistance of exhaust flow..... nothing will truely be gained...... BUT your car will sound a hellof alot better. as for the quality. dont worry none of those parts have any effect on the tuning or adjustments to our motors so it wont hurt a thing plus there is only 2 manufactures that really make intakes and they are distributed to dozens of sister companies.... you will pay for the name. there is no difference between a bosal, borla, and flowmaster. except price...... so basically you have nothing to worry about...... ebay is the way to go.
