I may consider letting mine go for the right stuff. email me what you have, and even though "stock pipes aren't valued" when its a maxi exhaust or whatever, the magnum exhaust I have is one worth keeping for years on stock. I do need an expansion chamber though, as well as a 15mm bing etc etc so let me know... and mayyyybe just maybe I'd let my pipe go.
p.s. whatchu building, an old school puch maxi? don't try to steal my stylo
