I know there's been loads of info. put on this site about Flowmaster series mufflers (and other exhaust mods) but it's way too much for a non-gearhead like me to interpret. So....I've heard the Flowmaster Super 40 will do a nice job of deepening the sound of the V6 and giving it a bit more of that good old American car rumble. Has anyone installed this muffler on a V6 yet? Any problems I should know about?
