I'm looking to upgrade the muffler on my 03 Tracker (2.0L 4cyl w/auto). My last vehicle was a wrangler with the inline 6, and it had a great-low rumble at idle with a flowmaster 40. Keeping in mind that my tracker is a 4cyl with a soft-top I would prefer not to have massive highway drone, but I would like a growl at idle/low rpms. I know 4 cyl's can only sound so good. My friend suggests a flowmaster 50, but I wonder if it would be too quiet? What do you guys suggest? Also, what is the factory entrance/exit exhaust diameter for the stock muffler? I want to get an appropriately sized muffler that I can just swap right in with the factory pipes.
-Thanks
