Default exhaust louder with or without cutout?

just a general question, i was wondering if my exhaust would be louder with a cutout i have cam headers y pipe. the reason i am asking is because i have slp loudmouth and no cats. would it sound the same coming through a cutout or will it be louder. i know cars are louder with cutouts that have mufflers. i dont want to waste my money on one if it is not going to be louder

It will be louder. The sound will be exiting right under your seat, and if the cut-out points down, it will echo off the ground.

It will be a little louder in the car, but given you setup it will probable be minimal difference. And from outside the car it probable will not be noticeable either

Inside the car it will be a lot louder due to where it will exit. It will be a little louder outside the car too. The loudmouth is a loud muffler but it still knocks down the sound some.

I have heard both on the same car and I actually thought the loudmouth was louder. Maybe it was only because it was piped straight out the back and I was standing behind the car where as the cut out is dumped under the car.

If you want a cut out ditch the lm1 and get a quiet cat back and install it in that. Theres no reason to run lm1 w/ cut out

Cut out will certainly be louder. The sound has the shortest diatance to travel to exit the cut-out which isn't shaped in any way to muffle the sound and doesn't pass through any mufflers. The longer the sound has to travel before exiting, generally the quieter it will be....mufflers or not. If cats aren't in the equation, the better the volume coming out the cut-out.

Have you heard them side by side? Its tough to tell which one is actually louder because they are both loud as hell.

As noted above, they are both very loud. I think the cutout would be a bit louder (depending on your reference point), however I'm not speaking with experience of hearing the two side by side.

I love my e-cutout because I can leave it 30 - 40% open -- it helps relieve the flow restriction of my catback (Flowmaster, blah) and I get the added volume to the exhaust note without a bit of rasp. Perfect compromise (in my mind).

I've had both. Loudmouth isn't all that loud too me. Not nearly as loud as my true duals, but then again I have a pretty healthy cam in the car now that aides the volume. I have duals dumped at the axle on one 'bird & cutouts on my other one.

Cutout will certainly will be louder and even with stock exhaust,cats. Sounds very good.

I think this is a trick question. A loudmouth muffler usually is mounted right after the y merge. And cutouts are usually mounted under the passengers rear seat. So that would mean that the cutout is located after the muffler? Wouldn't that defeat the whole purpose of the cutout?

Everyone hears things differently. To really tell the difference you have to hear both in the same area. Either one will sound much louder down town in a city than out on an open road. They both sound very close.
