Default What size exhaust piping does an 2004 accord ex v6 sedan have?

I was wondering so I could put a universal muffler on if there any suggestions for custom piping. I'll appreciate them thanks! And also was wondering how to take the governor off?

Most mufflers have different inlet and outlet sizes. The inlet is larger than the outlet to assure proper scavenging. Modifying the exhaust system, (i.e. modifying the exhaust gas velocity by changing exhaust tube diameters) can detract from the "ideal" scavenging effects, and reduce fuel efficiency and power if not properly planned out and executed.

To increase scavenging potential, the entire path from intake to exhaust (i.e. all powertrain parts) to tailpipe must be tuned in sync with each other. This will ensure that the air flow is never interrupted. You want to avoid universal mufflers and use exhaust systems designed for your engine. By naming your vehicle and engine type, all auto parts stores will have a recommended exhaust system for your application. Universal stuff is for tractors and the like.

As far as the governor, speed is controlled through the power train control module. You can get a recalibrated chip for your control module with governing properties turned off. Happy trails.
