Over the last couple years the priorities in my life have changed. Had Matrix Garage grown big enough to hire enough employees and leave them to running it while I pursued other things I would have happily taken that route but it has generally stayed just big enough to keep me working overtime. 
I have decided to start focusing my carreer and passions elsewhere and that means that supporting the AW, AE, 4A and related communities has had to be moved much lower on the priority list. I have decided to keep the store up to provide parts that only we offer, or other things that are hard to come by elsewhere. You will notice many big name, readily available products have been taken down and we will continue to do so. It's just not worth our time trying to compete with the big corporations selling at cutthroat prices and it just takes up more of my time. 
I will try to keep providing those parts that we make or that we have developed and sell as a service to the community but understand that now this is something I do in my spare time because I don't want to leave people hanging. 
I try to make shipments and process orders at least twice a week. If you want Amazon next day shipping buy from Amazon. I will do my best to keep order time and customer service at a reasonable level but have some understanding. I am not making money on this and it takes away from my other work and other issues that are very important to me right now. 
I have always wanted to make our designs and other information open source and available to the community but to do so properly would take a lot of time making sure that models and drawings were complete, accurate, or properly described. To go through everything and make sure it was something that I felt comfortable releasing to the community. I would love to find someone who was willing to help me do this. Someone in engineering school or passionate about this to help go through 3D scans, CAD designs, and information to prepare it. If you are interested feel free to email me.

T25/28 Mild Steel Turbine Outlet Flange 5 bolt


There are two common styles of 5 bolt turbo outlet flanges and I have not found differentiating names to tell the two apart. You just have to look at them closely and compare. I will try to get drawings up soon. I will also try to get the second style available soon. If you need one of the other style let me know and I'll get a batch made.

These are made directly off of Garretts drawings for a perfect fit and alignment.

Price: $30.00

Toyota Oxygen Sensor Flange mild Steel


This little flange is just the ticket for installing an original Toyota-style oxygen sensor on a custom header or exhaust system. It is made from 1/4" thick steel, and the 8mm diameter bolt holes are spaced 44mm center to center. This is the same as an AW11 sensor, but check the sensor you plan to use just to be sure before ordering.

Price: $14.00

SC Exhaust Flange Mild steel


SC flange fits the supercharged AW11 downpipe, catalytic converter, or muffler. Laser-cut from 3/8" steel with a machined recess to accommodate the OEM Toyota crush ring style gasket. 2mm deep counterbore on rear face centers flange perfectly on 2.5" OD exhaust tubing. Through hole is 2.4" ID. Great for building your own custom exhaust system.

Sold individually. Photo shows two flanges to illustrate front and rear sides.

Price: $28.00

20V Downpipe Flange Mild Steel


Temporarily unavailable



This laser-cut 3/8" steel flange fits the 20V header perfectly and is ideal for anyone who wants to build their own downpipe from scratch. The pipe holes are 1.70", which will accept 1 5/8" OD tubing, as well as 1 3/4" OD tubing that has been swedged or slotted to reduce its diameter slightly.

Nothing fancy here, just a piece of metal that fits right and gets the job done.

Price: $10,000.00

4AGE silvertop 20V intake Plenum Flange


This is the flange that connects the independant throttlebodies to the plenum. It can be used for custom plenums, turbo plenums and velocity stacks.
They are made out of 3/8" 6061 Aluminum but special orders can also be made to your spec.
There is a counterbore for 2" pipe which matches the area of the intake. You can special order a flange without this if you want to use different sized piping.
Right now these flanges are made to order so please allow a couple weeks for us to machine and ship them.

Price: $105.00
