I just recently cut the muffler off on my 2001 ram 1500( 1 cat), and it sounds the exact same! i was just wondering if maybe like carbon build up is keeping it quiet or if it will get louder over time. also if i dump the exhaust how much differnce will it really make, and is there anything else i can do to make it louder, i wanted to cut the cat of but it has one of those plugs in it and i didnt know what it would do to my truck if i cut it off.

 

When I did the exhaust on my firebird..... having JUST the cat, and nothing after it sounded quite mean. However, it also allowed a lot of exhaust into the passenger cabin... not good..... Removing the cat, and putting on a good free-flowing exhaust though, THAT sounded WAY cool. (after that, I never turned the radio on again....)

If you live where you don't have to worry about emissions testing, you can get an off-road Y-pipe, which will have the bungs for the sensors.. and flows a HELL of a lot better than the stock piece. If you have to have a cat, magnaflow makes a replacement that also has a better flowing Y-pipe.

Add a flowmaster 44, or even a 10.... and it will sound pretty good. Check out youtube for LOTS of videos featuring various exhaust combinations.

edit,, your cat would be easy to gut or replace with straight pipe or high flow cat

 

ya the stock cat kills us. with its stock y-pipe design. gut or remove it replace with straight pipe or high flow. i removed mine and put a aftermarket y-pipe to a flowmaster super 10. here is my newest video
