Wanting to get a better growl if you will from the marauder. Buddy of mine had an '04 cobra with flowmasters. Some of you reading may recall I don't know a whole lot, and I just don't know what is out there to 'beef up' my exhaust - and O'Reilys site has a ton of different flowmaster stuff. Would like to enhance it without having it unbearable for when we go on long road trips with the kids in the back. As always, appreciate any info y'all are willing to share!
