True enough, but the LAT73/LAT74 headers and exhaust, that these
mufflers were part of, were not really intended for stock engines.
My Tiger came to me with a five-bolt 289 with ported and polished heads,
a Holley 600 and F4B manifold, and a pretty lopey cam. 'Quiet' was not
really in its repertoire, although sticking with a 2 inch exhaust system
does help keep the overall noise level down compared with 2 1/4 or 2 1/2
inch pipe, at the expense of some performance at the high end.
