Cayman S exhaust on a Boxster

[berty987]

The 987and 986 use the same head and bolt pattern but the exhausts are designed differently to overcome the staggered position of the heads. On the 986 they chose the make the headers unequal and the connecting pipes to the rear silencer lengths the same. On the 987 they routed the exhaust differently and made the headers equal length and the rear muffler connecting pipes different lengths to compensate. Though I've not seen it tried I would guess a complete system could be fitted from a 987 onto a 986 but I would have to question the benefits ?

Flanges are different, exhaust ports are different, the 987 Cayman exhaust routes to the outside of the sub chassis and the catback is configured very differently from the 986 both in terms of "plumbing" and contact points . Mechanically speaking, even if it could be made to work , extensive fabrication would be necessary in order to make it fit . As Berty said , why ?
