I have the 2.5" X pipe exhaust system from the HO manifolds to rear bumper - minus the mufflers. I know the muffler choice is critical for performance and comfort in driving.
I plan on having the RARE HO 2.5" exhaust manifolds ceramic coated inside and out by a local shop. My research tells me that they will maintain their finish longer and it will create for less heat under the hood.
What is the difference between the Super turbo and Ultra Flo on the Dynomax 1774 Muffler?
