Review on Oeyal Matte Black Universal Slip-On Motorcycle Exhaust Muffler: 1.5-2" Inlet, Silencer Pipe for Street Bike, Scooter & Dirt Bike by Andy Mitts

I was a little hesitant to buy based on some reviews. For context, I have a 2017 Moto Guzzi V7. I didn't want to spend $1200 on a new high performance muffler as I just wanted a louder and louder sounding muffler so people could hear me approaching. So back to the muffler: Installation: Was easy! It took me less than 30 minutes for both sides. I used all three adapters that came with the kit to connect to the factory pipe and reused the factory clamps. No modifications needed as always for my bike. Sound: The sound is definitely louder and harsher. I don't think it was too loud but some may disagree. I would definitely go again and recommend it to other people with the same bike or similar if they just want value for money. In terms of performance, I don't know if the performance has decreased or increased, but after a test ride it became more responsive. Edit: I'm not sure what the moving DB killer is as no instructions came with it. I didn't see anything inside the muffler that could be moved to adjust. They are also listed as matte black but as you can see they are not matte compared to my matte black tubes.
