the catalyst tail is really lite weight fiberglass, great for the strip....
I will add a second layer of woven glass/resin to beef it up as I've seen a bunch of them damaged when used as they come from catalyst (stress cracks , rock chips). an air tech tail was on the bike before this and was waaaay heavier....... like 3 layers ....
no stress cracks at all...
I'm sorta anal about things like that...
