The manual tranny cars are quieter inside. My son's 98 has an off road H with 40 series Flows through stock tailpipes with 18" long 3" tips. It is barely louder than mine. Just the 40 series Flows has this awful drone in an automatic car, the rpm's are more steady. In a 5 speed, about the time the automatic car gets really loud is when you push in the clutch. Add to that my car is a convertible, so it doesnt have the package tray, so there is little insulation to quite it down.

The Force II Catback has 50 series Flowmasters with heat shields welded on, so the resonance is almost stock sounding inside, but much better outside than stock. It may be a while before I get the catted X (or H) but I plan to, they are just a little pricey, and I have other things going on right now.
