Adding a well-design, well-built aftermarket up pipe is one of the first things you should do to your Subaru. Our ultimate goal was to make the best up pipe the aftermarket has to offer.
Design
We designed this up pipe using our in-house FARO Arm along with the latest and greatest Solidworks CAD Software. This assures that we can offer you the most precise and best fitting up pipe on the market. OEM exhaust manifold pieces are inconsistent so we used our reverse engineering hardware/software to scan countless OEM pieces to determine the range of best fitments for our aftermarket pipe. This allows us to be very confident that your flanges will be leak free and the up pipe will fit perfectly, every time.
Materials
Our up pipe is made with the best local raw materials available. The flex joint is 321 Stainless Steel w/ an Interlocking Liner and the tubing is a heavy duty 14 Gauge 304 Stainless Steel (competitors use thinner 16 GA) that has been precisely CNC Mandrel Bent; our flanges are made out of 1/2" 304 Stainless Steel and are put through a tumbling process to smooth out the edges. The pipe is hand-welded on the inside of the flange, in addition to the outside, allowing for added strength to the finished product and a nice mating surface with optimal flow through the pipe. All fabrication is completed by our team of Certified Welders/Fabricators which ensures that each and every up pipe that comes out of our facility will handle anything you throw at it!

Continually striving for perfection, it's what you can expect from GrimmSpeed™
GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. On a more personal level, we are a group of car enthusiasts in the lovely city of Minneapolis, Minnesota who are absolutely passionate about what we do. 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, MN) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed of....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
Our team knows that if they propose a project 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 and make an impact on the enthusiast community.
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 drive 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. We 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. If we say we are going to call you back, we actually will.
