Lightweight, but quiet exhaust?

Lightweight, but quiet exhaust? My neighbors/wife/baby are getting tired of me leaving for work at 4:30am in my camaro. I have long tubes, ORY, then an 18" magnaflow bullet after the ORY, and that's it. I used to have a magnaflow catback but I ditched that 35lbs for the 5lb muffler. Any ideas on a quieter light weight exhaust? Would a turn down help any? I am thinking of putting another bullet after the current bullet and a turn down, but don't know how much that will help. I don't want to restrict flow much, and I hate the look of seeing any tip or exhaust on a car, the exhaust is the engines butt hole.

Flowmaster makes a bullet called the DBX that is a lot quieter. I saw a member go from the kooks true dual bullets to the Flowmaster DBX and it dropped about 20 decibels. He was having problems with the neighbors also and leaving real early for work and no problems now.

Very tough situation. I did the electric cutout thing for a while but you're right it's heavy. Adding an over the axle plus another bullet then a turndown would probably help some.

A couple of turbos could help to quiet the exhaust down. I know they add some significant weight, but there is a slight power increase that should offset it.

I know this is one unreasonably expensive solution, by the definition of "lightweight and quiet" would be a mix of titanium plumbing and OEM style high performance mufflers. And such a thing does indeed exist, but it can run $1000+
That said, the OEM muffler thing is on the table. Cut-outs allow you to have both, but if you run one I recommend using it to flow into another kind of exhaust system (not just an open dump which can be ear deafening/bad for hearing).
the best solution of course is the turbocharger in the rear position acting as a muffler and providing 40% additional power.

Just make a small diameter, large case muffler with a v-band flange and a single-point hanger. Run a single tail out from under the car out the side. When it's time for racey time, just unbolt the v-band clamp and undo the single point hanger and swap on the v-banded race muffler.

Crazy responses on here. If your neighbors really wanted to be ******** about it they could start complaining to the city and police about noise violations, etc. It wouldn't help your situation in the least and it's always good to keep the neighbors in your back pocket should crazy stuff happen when your not around like suspicious people around your house or something else random. I'd do what was talked about with a cheap, lightweight alternative exhaust that you could just remove at the track.
