    2015+ Subaru WRX Stage 3 Power Package by GrimmSpeed

    The GrimmSpeed Stage 3 Power Package is a well-rounded kit, offering increased power and torque output thanks to reduced restriction before and after the turbo, as well as a more aggressive street presence thanks to the intake and exhaust tones. Stage 3 kits include the GrimmSpeed intercooler and charge pipe, a combo that will not only increase safety with your more powerful setup, but will allow you to make addition power thanks to cooler charge temps and lower restriction at higher RPMs.

    The upgraded GrimmSpeed 3-Port Boost Control Solenoid offers more accurate and more responsive boost control and is a must when having your vehicle professionally tuned. The GrimmSpeed Intake adds an additional performance increase by reducing pre-turbo restriction, which allows your turbo to build boost more quickly and more efficiently. The GrimmSpeed J-Pipe replaces the extremely restrictive factory J-Pipe and catalytic converter with high quality 3” diameter stainless tubing and a high-flow catalytic converter. The free-flowing design of the J-Pipe offers superior boost control, and is the perfect complement to the Electronic Boost Control Solenoid. Over stock, the J-Pipe replaces a restrictive catalytic converter with a high flow unit as well as increases the tubing diameter. The result is a decrease in restriction after the turbo, an increase in turbine efficiency, and will further decrease time to spool as well as increase boost pressure.

    Features

    • Hybrid Cold Air/Short Ram Design
    • Custom reusable high flow air filter
    • Stainless Steel Construction - The J-Pipe is constructed of high grade 304L SS
    • 2-3hr Installation

    Benefits

    • Decrease Spool Time - Lower intake restriction and better boost control
    • Plug and Play into OEM Harness - No splicing wires like other BCS solutions
    • Stainless Steel Construction - The J-Pipe is constructed of high grade 304L SS

    This package adds soooo much ear candy it's not even funny. I didn't think I could love my car any more than I already did. You will not find a product sold by MAP that isn't quality. I've done all the installations of everything I have bought here myself and really havn't had to struggle much at all. Key note with this kit, you WILL need to remove the secondary boost restriction pill. There are a bunch of youtube videos on that and it's a really easy task. Overall the sound and power gains from this kit are amazing. Well worth the money and I would recommend to anyone.

    Bought this package and I had it installed 1 week ago. Putting down 310hp,290foot lbs of torque,JR tuned. What a wake up call.New car.Love the package.I also did IAG egr and tgv deletes,IAG AOS street.I can't believe the performance I get.Mated with a Nameless cat back with muffler deletes. Its loud.I was a little scared at first with the sound, now I embrace it.Police officer pulled up next to me yesterday,noticed I was twice his age and started laughing, till i smoked him.He pulled me over and we both had a great laugh, some one was watching over me. Love this set up,Grimmspeed is a quality product. Ian was great also. He always steers you in the right direction.This is an addiction, now I want more power,Rims,BBK. Thank you Ian.Thank you JR for a great and reliable tune.
