I just returned my car back to "stock" for an inspection except for my Zoomers axleback. The zoomers on my stock car are pretty damn quiet not going WOT, with no drone at all. I usually run an X pipe and I get a very little drone and trumpeting, but the Zoomers sound awesome WOT. They also look alot better than flowmasters.

anyways thought Id give you another option since not many people run the Zoomers. They are in the same range as corsa

 

Yeah...I've never heard of the Zoomers (not that that means anything). I'll look into them.

 

MY 2 cents, I hate drone and I love the FR500S KR mufflers deep, loud and ZERO drone!
