How much did you spend for those ( three toghether) ? wanna put those on my GS
D. C. - The intake was $600, B-pipe was $140, and tanabe medallion touring exhaust sys was $800. I bought the intake and ecu through swift racing at www.swiftracing.com and the b-pipe and exhaust sys through driven by style (megan racing products) at www.drivenbystyle.com. Kind of pricey, but IMHO worth the money.
I bought the intake first and the exhaust sys at a later time. Once the exhaust was installed, overall perfomance was greatly increased. I dont have access to a dyno, but by my seat of the pants testing, there is a very noticeable difference in performance with all three working together. All very easy to install. Read the installation instructions for the intake and ECU very carefully though. Enjoy!
