Re: Exhaust shields same on 90/91 CQ?

The 90 coupe came with a S-tainless S-teel, hence my abreviation to SS,

It is made of 5 pipes welded into what approximates a somewhat straightened
er, human exhaust (8^0).

The smooth bore and circular cross-section of the 5 pipes is optimal for
exhaust breathing.

The alternative is the cast manifold that the 91 coupe has, which is not
round, internally, and is not perfectly smooth, either.
