Sup guys,I just finished "stage .5" on my car lol.

Here's the parts list
'00 Si-B16a2 block/completely stock head
MemoryFab whale ***** intake
NGK "blues" plug wires and Laser Iridium plugs
'01 spec ITR intake cam
'01 spec ITR exhaust cam
DC Sports 4-2-1 header (usdm collector size,2.1" i believe)
Megan racing resonated test pipe
Greddy Ti-C catback exhaust


It's a bit loud for my taste right now with the test pipe, so I was wondering. Does anyone make an axleback for this car?the Apex'i WS2 in particular?

Also,someone in the dyno thread is running an almost exact setup and said he is making 155whp tuned. What do you guys think i should use for tuning? P28 + ?....crome?Neptune? which is the easier to tune and better priced?

thanks for the help
