I have a Comptech supercharger with aftercooler. and a spugen catback single exit. thats it so far for performance mods what will help out the most the ricks <richmond> 3.57 final drive or a good header like the j's? they will end up costing about the same so any info is helpful! ohh and how loud does the s2000 get with a test pipe?

 

You will see the more dramatic effect with the gears. BTW, they're 4.57's. A header would be nice but you won't notice the improvement nearly as much in terms of performance.

 

4,57 gears,no doubt;you can even get 4.77.!!!

 

IMHO I understand that the gears are a better value and effort as for performance..
