Looks Fantastic

Very happy with how the silencer looks on my wife's 2024 Vespa GTV. Its not as light as I thought that it was going to be. But I guess its a sign of the build quality. Sounds very nice with the baffle removed and makes her more visible on the road due to the exhaust tone, which is a must where we live.

Arrow titanium exhaust headers without muffler 'Open Box' from Bill's Exhaust

Item as described. 'Open Box' but everything needed was in box. Kinda difficult to install but love the way it sounds. Wish it came with the Arrow muffler

PHENOMENAL !!

Thrilled to finally have found a fair price for a race exhaust. Super grateful for the good deal. The Vandemon exhaust system is unreal ! The sound is phenomenal and I noticed instant power gain.
