The above car had JWT Popcharger, Kinetix Plenum, Test Pipes, and Injen Exhaust.

 

hey! i was wondering if a pro-1 exhaust, pro-1 y-pipe, and pro-1 headers combined would still be legal and pass smog n carb n all that stuff...PLEASE LET ME KNOW! THX!

 

Right here.

I purchased the TopSpeed headers as well. I had them installed the day after they came in at 4myride.com. I haven't been able to dyno yet, but the butt dyno says there is deffinitely more horsepower. The last time I dyno'd was at the last Stillen day and then I had 254.5 to the wheels. Since then I have also installed: Kinetix Plenum & cats. So I am excited to see what my car is making now.

 

Anyone using the fujitsubo headers? Does anyone know if the fujitsubo hearders are legal here in California? i plan on buying fujitsubo exhaust system, y pipe and headers. I wanna make sure my car will still pass smog. THANKS

 

The baseline dyno is not correct ... torque and horsepower curve do not cross at 5252rpm ... a physical impossibility!

I wouldn't read into that plot.
