How loud is the muffler? I don't want to hear it at cruising speed.

make sure you have a real catalytic converter otherwise it is loud. the only other problem is exhaust mounts are lower than stock and I have scraped several times.

Not loud at all. I have it on the ceiling in my basement workshop, and I do not wear hearing protection. Even on highest speed it is quiet.

I haven't been pulled over for noise violation yet, but you can definitely hear me coming a few blocks away when I open it up. It's louder than the Flowmasters I replaced on my Grand Prix GXP.

It is not an overly loud tone. I would call it a more throaty tone, but not overly aggressive tone. It is much better than what comes with the car. If you are wanting something loud and aggressive, you should go with one of the other 2 exhausts that Borla sells

It's not too loud but it is loud.it comes with a silencer that gives it a nice smooth tone.without the silencer it is a very deep tone but you won't get pulled over by cops.

I installed it without the wind deflector and it's pretty noisy on my car. I'm going to install the deflector and see if it quiets it down any.

The unit is about medium noisey. Naurally the faster fan makes more noise. But as usual, once it on for awhile your hearing ignores the noise.

Not that loud interior noise, still is a drone over 55 mph though. Had a Flowmaster 10 on before this on and was twice as loud. Super 40 seems just right

I was kind of surprised at how quiet it was myself. you just hear a little rumble from inside the truck. I actually have to turn off the radio to hear it with the windows up or down, doesn't make much difference. its a little louder when you get in the throttle a bit. hope this helps

You can definitely hear the exhaust. I pull 30ft. Gooseneck often. It's not obnoxiously loud, but you can hear it.

It actually isn't loud when your driving normally. Say on city streets. However stepping on the gas and on places like on the highway you can hear the big difference in sound. That's where it can be loud. It's not ridiculously loud. But it's satisfying loud :)

I don't think you can make it louder. The only option would be to go with a borland exhaust but I think it is overkill or disconnect your exhaust all together, but that is illegal.

not sure. been told its pretty quiet already. could try putting more batting in muffler but will restrict some air flow.

It's definitely louder than stock, especially if your a heavy on the accelerator towing a trailer. I don't hear any more noise towing vs regular driving. My other dodge diesel had a 4" straight pipe and that was borderline obnoxious. This system has nice tone, the 5" pipe with the muffler I would say that it's at least -10 dB quieter than the 4" without a muffler.

Not really more than stock noise no. If you got an intake or something I'm sure it would be more audible. I bought it to hold my high boost levels though not for the noise.

You can hear it at about 35 mph as long as you're not riding a loud bike. What bass :>)?
