One more exhaust question... where exactly is the ideal and practical place to start the increase to 2" on the stock exhaust? I'd like to know exactly what to tell the exhaust shop when I go in.

Going to 2.25" after the muffler is pretty self explanitory.


>>>*We normally ran them down the street to a local muffler shop and had them fab it up, they always started right at the existing manifold flange.

I know of several running 2 1/2" all the way, and one Celica with 3" all the way and the folks seem to like them.

Bigger typically means slower gas flow, simple as that. The system likes velocity, so bigger exhaust area would move the power peak up the RPM scale a bit....*EB
