Description

With the 2015 J-Pipe, the devil is truly in the details and the product development team here at GrimmSpeed has taken the time necessary to knock each of those details out of the park. As a result, what you see here is a meticulously engineered J-Pipe with an innovative flange design, single piece construction, excellent ground clearance and fitment with superb quality and craftsmanship.

Performance of the J-Pipe was verified on our 2015 WRX using the following method. Our tuned baseline run is the same run that we used in showing the boost control performance of the GrimmSpeed 3-Port Solenoid. We then installed the J-Pipe and retuned the car, using the exact same tuning methodology to ensure consistency. This ensured a real apples-to-apples comparison between the stock J-Pipe and the GrimmSpeed unit. The results showed a gain of 26.7whp (14.1%) and 19.8wtq (9.0%) and are displayed in the chart to the left. The percentage gains should be the focus here, as this particular dyno reads very low (stock baseline was 171). From a completely stock vehicle, users can expect a gain of around 45whp (27%) and 70wtq (41%) with the installation of the GrimmSpeed J-Pipe and custom tuning. The chart on the right shows this comparison.

Our engineers began by 3D scanning the OEM J-Pipe and vehicle underbody using our in-house FARO Arm. That data was used in CAD to design a pipe that fits perfectly within the tight underbody packaging on a 2015 WRX without sacrificing ground clearance. The 2015 WRX uses a series of OEM brackets to support the weight of the turbo and J-pipe, the most important of which bolts to the turbine outlet flange. Our engineers insisted on using thick 1/2" stainless steel flanges, but also knew that without a clever design, the very important OEM brackets would no longer line up. The GrimmSpeed flange design uses a CNC machined pocket that the OEM bracket sits in during installation, allowing the use of 1/2" thick flanges as well as the factory turbo support bracket! Finally, they worked tirelessly to design and manufacture a J-Pipe that could be bent from a single piece of tubing. This allows for more efficient manufacturing, less potential failure points and a product that fits perfectly each and every time.

Features:

  • Innovative Turbo Flange Design - 1/2" thick while retaining all OEM brackets
  • One-Piece Tube - Ensures exact fitment, robust construction and ease of installation
  • Smooth 3.5" to 3" Transition - Matches turbine outlet size and then reduces quickly to maintain exhaust velocity
  • 100% Made in the USA - Manufactured right here in Minnesota
  • Optimized Tube Routing - Maximize ground clearance and minimize flow restriction without modifying suspension hardware, etc
  • Custom Stainless Turbo Studs - Replace the terrible OEM studs and nuts with these, machined specifically for use with 2015 WRX turbine outlet and our 1/2" flanges
  • Standard 3rd O2 Bung - Allows the future use of aftermarket sensors
  • Grounding Strap Mount - Retains all factory functionality
  • 300 Cell Metallic Substrate Catalytic Convertor (Catted Models Only) - Excellent balance of the reduced restriction of a 'race cat' without the stink of a 200 cell unit
  • Expertly made from sturdy materials
  • Made to help enhance the performance of your vehicle
  • Perfect solution for racing and high-performance engine applications

In true GrimmSpeed fashion, no corners were cut in the fabrication of each and every one of these J-Pipes. A proper design is no good without proper material selection. In this case, 304 series stainless steel is the best choice for durability, corrosion resistance and cost efficiency. Flanges are machined from 1/2" thick plate and the primary tube is CNC bent, laser cut and expanded from 3" tubing. O2 bungs (three of them) and our custom turbo studs (included) are both machined on a CNC lathe from 304 rod. Finally, finished assemblies are TIG welded using 308L filler rod.

Last, but certainly not least, is construction. A solid design and robust materials are nothing without use of the correct manufacturing methods and welding processes. Each GrimmSpeed J-Pipe is welded in the same master weld fixture. When not in use, a 'master pipe' lives in that fixture, allowing for a quick check, before each production run, that the fixture is still accurate. Even that isn't good enough for our engineers, so they 3D scan the fixture and master periodically, to ensure accuracy.

Includes:

  • 1 x Welded J-Pipe Assembly
  • 1 x GrimmSpeed Stainless MLS Turbo to J-Pipe Gasket
  • 1 x GrimmSpeed Stainless MLS J-Pipe to Catback Gasket
  • 4 x Stainless turbo studs w/ nuts
  • 2 x Replacement catback bolts w/ nuts
  • 1 x O2 Sensor Plug (plugs third O2 bung for future use)

Additional Info

GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. On a more personal level, we are a group car enthusiasts who are working our passions in the lovely city of Minneapolis, Minnesota. Our bread and butter started out anything Subaru. However, after growing our team and engineering expertise, we started developing products for Mitsubishi, Ford, MazdaSpeed, and Hyundai markets. We are a true garage start-up (single stall townhouse garage in Maplewood, Minnesota) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed....actually, much more. We have a wide breadth of product offerings including; intercoolers, exhausts, intakes, gaskets, engine pulleys, phenolic spacers, boost controllers, and many more.

Most of our decisions at GrimmSpeed are based on 3 basic principles:

1. Innovation

My team knows that if they propose a project to me there has to be at least one new innovative feature. It may be a completely new idea or an innovation to a current product on the market. We truly love creating products that really work. 

2. Keeping Jobs in Minnesota

Lets face it, manufacturing in the US has been lost for a long time. It's sad because manufacturing is what this great country was founded on. Our goal is to do our part in bringing it back to the US. Lets show the rest of the world that we do still 'have it'. Almost all of our partners are right here in Minnesota, most of which are within an hour of us.  Its not always about the $ and we are here to prove that.

3. Customer Service You Deserve

What flies for customer service these days just continues to astonish us. I don't have to tell you guys, I'm sure you are all well aware of some of the terrible customer service that goes on these days, especially in our industry. Our goals are to be honest with you, if something is going to be delayed, we aren't going to give you some made up date when it will be ready....we will tell you exactly the most current info we have. If you need help installing our products we will be there on the phone or email ready to help until you have figured out the issue. Last but not least, we will keep our word.  Plain and simple, if we say we are going to do something, we will.

JM AUTO RACING carries a wide range of performance auto parts, as well as car accessories and truck accessories. Whether it be body styling such as body kits, hoods, trunks, splitters, spoilers, and carbon fiber items; performance auto parts and car accessories such as turbo kits, superchargers, intakes, exhaust systems, cam gears, clutches and flywheels; suspension accessories such as coilovers, shocks, struts, springs, sway and strut bars, alignment kits and tie bars; or lighting accessories such as projector and euro headlights, HID kits, bumper lights, taillights, brake lights and undercar lighting, JM AUTO RACING has it all.

Warranty

What is the GrimmSpeed Limited Lifetime Warranty Policy 

GrimmSpeed-branded products are warrantied to the original owner against manufacturing defects in materials and workmanship for the lifetime of the product.

If a GrimmSpeed-branded product covered by this warranty fails due to a manufacturing defect we will repair the product, without charge, or replace it, at our discretion. Only original, unaltered and unmodified materials and workmanship are covered by this policy and you must provide proof of original purchase to be fully covered. This warranty does not cover damage caused by accidents, improper care/installation, negligence, reasonable/normal wear and tear, or the natural breakdown of colors, coatings and materials over extended time and usage. GrimmSpeed cannot be held liable for any damage to your vehicle and/or its components caused by failures associated with the previous statement. Damage not covered under warranty may be considered for repair for a reasonable rate or a reduced price for a replacement piece (a fee will be charged for return shipping).

This warranty is available in the United States and Canada.

This warranty does not cover products sold by GrimmSpeed that are not GrimmSpeed-branded products.

This warranty gives you specific legal rights; you may have other rights, which vary from state to state.

The GrimmSpeed website sells GrimmSpeed-branded discontinued, special make-up, and slightly blemished products at significant discounts as 'factory seconds' products. This warranty does not necessarily cover any products purchased as 'factory seconds'. The GrimmSpeed Warranty Department may repair 'factory seconds' products for a reasonable charge and a fee will be charged for return shipping.

Is normal wear and tear covered

The GrimmSpeed Limited Lifetime Warranty covers manufacturing defects in materials and workmanship, but it does not cover normal wear and tear over extended time and usage. Wear and tear is damage that naturally and inevitably occurs as a result of normal use. Regardless of how carefully you use, or how well you care for your GrimmSpeed product, like all performance parts it will eventually begin to show age and wear. Common examples of wear and tear that would not be covered under the limited lifetime warranty include denting, abrasions or scratches, color changing from heat in exhaust components and so on, less common examples include flex-section wear and fatigue cracks over an extended period of time.

How do I send my product in for warranty

The first step is to contact [email protected] and let them know of your issues/concerns. From there, a customer service representative will personally work with you to determine the best path forward. For the quickest service, please include your contact information and photos of the failed product along with a copy of your receipt/invoice in your initial email.

Upon request from your customer service representative, your product must be returned directly to The GrimmSpeed Warranty Department at 650 Taft St NE, Suite 300, Minneapolis, MN, 55413. All shipping to Warranty must be pre-paid and insured. GrimmSpeed cannot be liable for lost in-bound packages.
