I hate to be a buzzkill, but you obviously performed zero research on exhausts before you made these decisions, or you'd have not made them. What you've done to your exhaust reminds me of those people who get drunk at parties and agree to let their mate Dylan try out the tattoo kit they bought off ebay for $60 - the idea was probably put in your head by someone else first, you got started on it without thinking it through and now you're stuck with NO REGERTS unevenly positioned on your chest. Because what you are stuck with now is a rolling canary disguised only by how well you drive it and by how close to standard issue quiet you keep it. Because one look under your car is going to invoke the Road Safety (Vehicles) Regulations 2021 and the Environmental Protection Act, either of which will get a big yellow sticker installed on your windscreen and see you catching the bus to Dylan's place for however long it takes you to make enough money to replace your current exhaust, because not having a catalytic converter installed is terribly illegal all by itself and I've no doubt it's not the only infraction present on your car.
Replace the exhaust, get a sh1tty tattoo instead and find a less expensive way of p1ssing off your neightbours.
