Hey everybody. I have a 2003 dodge ram 1500 quad cab 2 wheel drive 5.7 hemi. (automatic) I have a volant air system, airaid throttle body spacer, hedmen headers, superchips computer, and a 70 series flowmaster dumped off right before the axle. With no resonators. My truck doesnt sound nearly what I want it to. Although people can pick my truck out a mile away. It does have a very destinct sound but I want louder. BUT CLEAN! DEEP! I was reading here that all flowmasters lose power on the hemi's. Except for the HD50 Muffler. I would love to get the super 40 on there to really get the sound out of it but if were talking a major horsepower difference between the super 40 and the hd50 then maybe the 50 is worth going for. My truck is fully layed out on airbags on 24's. I have a loud *** system and love to cruise. I would pick sound over power but...... Well u get the idea. I just put the hedmen headers on my truck and didnt notice a sound difference. I know they can be opened up but how? I would be willing to take off the cat if it would sound clean. Forget the neighbors and emissions. Any input would be appreciated. Check out my website for more info on the truck. www.cardomain.com/id/blairski. And Im always up for new suggestions. Thanks

 

Replace the cat with a high flow cat. If you want noisy mufflers, go with the 40 series Flowmasters. If you want a deep sounding muffler, go with the 50 series Flowmasters. If you want to have fun and play with drag style pipes, get a couple of turnouts (y-pipes) from Summit Racing. When you want to race, or be loud, it just allows you direct the exhaust straight out avoiding the mufflers...

Then you can turn it back into the mufflers and have a semi quiet truck again.
