Does any one know how loud these nitro engines are just what to get an idea of what to expect?

I think is about 60-80 decibel ok so is not loud but maybe at night in a Quite neighborhood will be loud

Thank's for your Question. Sorry to tell you, but this thing is very loud. It turns at a very high RPM. So it screams.. So, you might want something larger. They don't have to work as hard. Good luck.

Since the monsters are larger the Cobra's may not be as loud. You can talk over them at idle but they have a nice bark when you get on the throttle. I'm really happy with mine.

yes its all the same as far as the intake goes, just be aware of the noise this is going to make. you can hear bpv a lot more

Its about as loud a medium box frame fan. although this varies alot on how you have the exhaust set up.

It is pretty reasonable. Unless you actually get on the gas they are pretty quiet. No baffling material inside, but there is a back-pressure piece. Love them, did not have the fuel injection reprogrammed and the bike runs great. Get lots of complements of the looks. Happy with them. Good Luck!

Hey Melissa--I have the exact same year nitro. I was kind of skeptical also--they work perfectly! Go for it!

Maybe a few sounds great if ran with the factory exhaust exit in the rear you will notice it will like to pull longer in gears and the rpms hold nicer mid to high range I run it with a spectra cone high flow air filer so she can breathe.

Victor, you really should not have any problem finding a new Nitro Star T 3.0 engine, look again for specifically for a Nitro Star T 3.0

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.

They get pretty noisy at anything above 55 mph. Only recommendation would to not overfill them. They were tolerable up until I had them rotated and the shop overfilled them past the max psi.

You will have no issues with noise with this unit. It is a very quite motor and especially at the speed of 1.5 you will barely hear anything

With the "silencer" on its not unbearable. With it removed its LOUD AS HELL. Not even kidding. There are a decent amount of videos on youtube you can check out as well

To me this is classic sound for a truck! I have them on a 78 bronco with a 460 motor and love the sound! Also same exact mufflers on a 56 f100 truck running a 302 and love the sound there. If your piped all the way over the axle the sound is perfect and not to loud. If u dump in front of the wheel or turn down before the axle it might be a little loud from the side but still would not be as loud as a flowmaster 40 series or anything like that.

Yeah I have mine on my 07 cobalt ls. It sounds really good, but if you take the silencer out it sounds like every other rice burner. But yes, very nice sounding muffler. There's vids on YouTube, before and afters, that's what made me buy it. I got that and a k&n short ram intake and my Slow 140hp 2.2 4cylinder sounds like a freakin beast. Everyone alwaaaays asks if it's an ss. Oh and it even improved the torque a little bit. Just enough to notice. But I highly recommend you get a k&n typhoon intake, gives it a great sound at high rpm and gives about 5 more horsepower and quite a bit of torque.

I struggle saying any gas driven engine is quiet. It would not prevent me from sleeping at night, my neighbor can hear it but I would not call it obnoxiously loud.

I honestly do not know what it would sound like on a 4 cylinder engine, I've only used it on the 5.7L HEMI V8. I would have to say (this is my SWAG as I'm not a scientist by any means) that I think the "deep" comes from the V8 engine note / sound being passed through the muffler, not the muffler itself making the deep sound. So if you were to hear an I4 and a V8 engine straight from the headers (uncapped) side by side the V8 would be both a louder and deeper sound than the I4 so as a guess, I would have to say that I think it is only going to make the I4 engine sound louder (than the factory muffler) but not deeper.
