I want to find a metric extension to give me about an extra 1/2 to 3/4 inch below the cowl. I installed the engine and it's right on the money as far as distance from tyhe firewall. If I dont lower the exhaust, i'll have to cut the crap outta the cowl and I dont want to if I dont have too.

Anyone know of such a thing, (mabee from o.s. or some other manufacturer), I would appreciate it.
