Haha, thats alot of theory i haven't thought about at this stage.
Basically it is going to be a staged approach. Getting the engine in and running stock with the exhaust, then modifying it later on when i have some more $$$. But i just wanted to do the exhaust right the first time.

oki cool.. easiest way to do it 
what sort of CFM will your motor be ingesting?? (since exhaust will be proportional to ingoing air) you can compare that with other motors and their recommended exhaust sizes..
i think that about 2" on a 1.3L is a good size....
hmm, 1.3L -> 7000 -> 2"
gives about 3L -> 5000rpm -> 2.56" (assuming they have about the same volumetric efficiency, and simple math between sizes/rpms)
if you were to go to 7000rpm, then 3" might be good...
i'd be guessing that somewhere's between 2.5 and 3" would be ideal... so what are the specs of the grunter motor?? ie size, rpms etc??
Cya, Stewart
