Firecracker installation — logbook Toyota Will VS 2003

We put a firecracker (muffler) with the godfather. They did it themselves, having previously ordered an adapter from the turner from the native diameter of the exhaust pipe to the muffler inlet. In the evening, before installation, I estimated the length of the adapter and in the morning they gave the application to the turner, and during installation it turned out that I made a mistake with the measurement and therefore hung the issue on snot until the next day. The next day, they ordered another adapter and welded it end-to-end to the already installed one. The crackers made 4 cuts on the inlet pipe and fixed it to the pipe with a screw clamp. The suspensions were made of a stainless steel rod with a diameter of 10 mm with a thread, and after installation, nuts and washers were screwed onto the suspensions, so I won’t lose the cracker for sure.
Now what actually came out of it. There are no whistles, grunts, farts, only a quiet bass from 2 to 2.5 thousand revolutions. But my wife and daughter did not appreciate my show off, as a result, I specially bought fifty-millimeter foam rubber and paved the trunk floor and the floor under the rear seat with it, it became quieter. My ladies said that it became normal. But today we were going to Sranodyr and, to be honest, even the monotonous, albeit quiet, bass strained me a little. As a result, now I am thinking about removing this whistle, buying a beautiful nozzle, making it for my native outlet and calming down or leaving the cracker and testing it some more.
