I would like to add some power, all I have is the JWT popcharger. Would you rather have the intake plenum or the borla exhaust for extra ponies? Has anyone dyno'd their results?

 

Do cats and a plenum in one shot, it will be a vast improvement over stock, you will notice power, sounds much meaner, and still looks stock to others but it will def. be faster than the G next to you... given he is stock. I have a kinetix plenum and cats and you can get them for cheaper than what you could get a borla exhaust system for.... Listen to nismo and fuji before you set you mind on borla as well.....

My guess would be that if you only installed the plenum or the borla (and did no future mods) your gains would be pretty close. If you ever plan on adding a z-tube and high flow cats (or straight pipes) I'd definitely recommend the crawford plenum.

Z-Tube + Crawford Plenum + h/f cats = 20bhp. Check the Central FL Dyno Day Results are in thread for details.
