Apples to Oranges....

300 cubes versus 200 cubes. 300+ horse versus 150. Headers make a decent difference on higher cubes and higher horse. On a Ranger, it's an expensive option with very little gain. I only noticed a very slight tone difference and a slight improvement in power high in the RPM range. Unusable improvements in my opinion. However they look better than the cast manifolds through the wheel well. I not forcing air like Logan is above. My engine is essentially stock with new exhaust and an intake system with custom filter box.

Just do a new cat back. The Flowmaster Delta 40 sounds best on your 4.0L OHV. Bumping to 2.5" piping will deepen the tone too.
