Exhaust Upgrades

["Nick Gemas" <gln@worldpath.net>]

Greetings All,
    I  have a dual Ansa system in my 74 TR6 and I'd like to replace the mid
section of the dual pipes with a single pipe. I've read this is done quite
often to even the exhaust note, cut down on the drown and added performance,
question is what size pipe should I use? 2", 2 1/4" or 2 1/2" ? If it
matters I have a hot street cam, 10:1 Comp. and Goods triple Strombergs,
ported head ect.............
    Any input would be appreciated.
Thanks again,
