Made my own down-pipes for Hedman shorty headers
There's a 7 or 8 page thread in the exhaust section about those headers...I have them installed in my Scamp as well...I bought some mandrel 2.5" U bends from Columbia river mandrel bending and had my exhaust shop weld up the sections with the same idea in mind...I think the pics I posted are on 6 or 7...
