I have had my flows for a couple months and I really like them. I sometimes wish they were a little louder, they are definitely not as loud as the ones made for previous years. Many people have talked about drone, but I only have it at very low rpm in 5th gear, which I am seldom at anyways. Much lower, deeper growl than stock. A friend of mine put the magnaflows on and took them off after one day, he now has the steeda system on and they are pretty loud. I recommend the flows only if you are looking for a deeper pretty aggressive sound. If you want really loud, head turning sound these are not for you.

my flows sounded great when i first got them, not to loud. this is good, bc my cats and x pipe made them a bit louder. i plan to go with long tubes and no cats in the future, so i think the flows are perfect for a growing system like min, or just by them selves with the factory stuff they are great too. and if you want more loudness and keep the deep tone, go with the mac pro chamber, it replaces the h pipe and gains about 3 hp, more than all the other x-pipe.

I've had mine about five months now. I love the sound. Deep and mellow at idle and good growl on acceleration. They also have a rather nasty aggressive sound during deceleration too!

I put them on my 05 and they do sound great. Not MUCH louder at idle...but definitely deeper and throatier. Then on accel it sounds GREAT and decel sounds great too. The onyl problem I have is the drone when running at abotu 2K RPMs in 4th and 5th gear.

Cool, I think this is what Ill be putting on mine also. Was a toss up vs the flows, and bassani. The price became the winning factor.

Nice Johnny! :drink: Glad you're happy with them, makes me feel even better about choosing them.
I am thankful I have an 8 bay shop with lifts at my disposal 24/7. Perks of being a manager of a goodyear store. That 60 bucks can go towards the next mod!

Love my Flowmaster American Thunder -- everyone has commented on the sound -- there was also a definite improvemnt on the sound once I SCT tuned for 93 octane.
