Sorry for clouding the conversation with facts i should have known better. Thanks Your info HAS been discussed here before.http://www.foxtbirdcougarforums.com/showthread.php?19019-ler-flow-tests-and-Exhaust-theoryJust sayin'My first cat was an '87 3.8.I kept the stock manifolds, put dual 2.25" pipes on it with catalytic converters and Thrush turbo pack lers. I know plenty of guys that have put duals on 3.8 litre Mustangs and IMO the setup on my old 3.8 sounded WAY better than all of them. In no way did this car sound like an import. Deep basso rumble at idle and part throttle. It started to get the hint of the sound of a radial engine at full tilt. It was LOUD though. It rivaled Ford 4.6's with SLP Loudmouths as far as sheer volume. Car alarms were set off on a regular basis. Quote Selected
