Don't exist. Best thing that I've seen is gonna be a custom exhaust that's bent and installed. I know on my Explorer I have 2" piping from the Catalytic Converter to the Flowmaster 40, then into a turn down. If I didn't it differently, I'd have 2.25" pipe like I have on my Ranger and it's PERFECT. Growls nicely when it's idling, but at cruising speed you can't hear it that much, but gives a good drone right there at the 1900-2200 rpm speed.

so from stock catalyst a 2.25'' pipe to a flow 40 is best?
