What's up everyone, I just picked up my 2006 Grand Marquis LS brand new in February. I know it's not the best platform for going fast but I'm going to do everything in my power to make this thing RUN! 
So far I've just got dual flowmasters on it but that's going to change soon...I'm on CV.net too, see ya'll around.

to GMN mang. That's a great GM ya got there. You have many options for mods, here's a few: Marauder airbox and SCT tune, ported heads and intake, (i'm not sure, but I think there are performance headers for 4.6's out there), O/R h-pipe if you don't already have one(you'll need an O2 eliminator for this) or high-flow cats if you need to pass a sniffer test, shift kit, trans cooler wouldn't hurt, lower gears, stiffer shocks/springs, and maybe some better tires. Keep in mind that this stuff isn't cheap, but most people think it's worth forking over some money for. We hope you'll visit this site as often as you can, for help with 4.6 tech or any car related issues, or for any other ramdom BS you can think of.
