I fitted the Hogzaust stage 3 (fairly thin SS washers, cause I only got a 3.6mm gap from 3 washers) onto my 2006, 3.0L Spec B sedan and it sounds fabulous. It gives the car a nice deep rumble at low revs. Thank you for all the good info Hogmeat and the rest of you that also posted helpful hints.
It only took ~30 minutes, luckily for me with our Australian weather (always sunny and no salt on the roads) the original bolts were like new and undid quite easily and the gaskets also pealed straight off (should be able to reuse. I made the same mistake that others have before me, which was to drop a washer into the pipe, but I did as previously suggested (start the engine, accelerate and blow the washer out... and it worked).
HINT: If you don’t want to drop washers into the exhaust pipe, locate the bolt at the high point first.
Too easy and cheap, great mod….. I’ll keep this one for a while.
