i just wanna ask if the race muffler's would give me more HP and Torque compared to the Maganaflow dual performance exhaust? Also would it be better to have 2 race muffler's 1 one each exhaust pipe compared 2 one considering i have a true dual exhaust and a magnaflow x pipe?

My opinion I would go with the racing xl dual in dual out I think you will loose power going with tru duals you have to have a lil backpressure if you dont have some backpressure you will loose power with your bottom end.

Yeah would i'm guessing power wise i could just but a magnaflow and have more power and torque than my flowmaster because the magnaflow flows straight thru causing the gas air ratio to move much faster making performance and power better.

the race muffler's are more designed for special applications...

if your looking to go true dual's on your truck, then I would just stick with a DI/DO Magnaflow ( X-core ) muffler. You get a 2 for 1 combo...

Yeah i mean basically i'm just askin since i got true dual exhaust with 2.5 inch pipe ran from manifold's back but i just installed a magnaflow x pipe to give me back pressure and more hp and torque along with it and even the flow.I also installed a flowmaster 40 series muffler true dual and it helped even more run's way better than stock! I was mainly wanting to know would a magnaflow give me more air flow and add a few hp and torque also?
