A freer flowing cat-back exhaust allows the engine to breath out the waste gas easier, yielding more horsepower as well as a deeper exhaust note.
I must say I have the 2.5 Dual Magnaflow catback and Man this system !ROCKS! It made a huge difference in Performance and gas mileage. Wish I had done it years ago. Exhaust has a deep tone and has Great Mid range power. Also Price is on the money. I was going to buy a single but just a few more buck it was So worth getting Duals. I give Josh at Trubendz 5*.
