Default Latest Fab Work @ MAPerformance

Hey everyone, my name is Chris and I'm one of the fabricators here at MAPerformance, along with a few others whose work you will also be seeing here in this thread. I've been a long time lurker outside of work in fabrication forums, and here in the evom fab section as well, and we figured that we would let you guys see some of the awesome fab work we get to do that most people don't even know we do, and that most people will never even get to see! Plus, who doesn't like looking through new fab pic threads

Mods: I am in NO WAY using this thread for any kind of marketing purposes, or to generate sales. The purpose of this thread is simply to share our work, and add to this already awesome fabrication section

We'll start with some honda love This customer originally came to us for engine assembly. We spec'd out, and assembled a beautiful longblock for him, and he decided he wanted a turbo kit to match!
- V-band schedule 10 ramhorn manifold
- PTE 46mm external gate
- 3" pie-cut stainless downpipe
- Stainless dump tube

This next manifold was built for an Evo that we had originally set our stock evo ecu horsepower record with. The setup on this car, mated up to one of our 2.4L's yielded us 814hp, and 622hp at 41psi
- Custom top-mount schedule 10 T3 manifold
- Twin Tial MVS wastegates (a second one was added after the pictures were taken)
- Stainless 3" downpipe
- PTE 6765 turbo

I wish I had taken more pictures of this car, but unfortunately these are the only ones I managed to grab I was a bit skeptical at first about how a 3.5" aluminum exhaust would sound on an SRT-4, but surprisingly when we fired this car up it sounded amazing! The aluminum gave it a nice, deeper than normal tone. The exhaust features twin vibrant aluminum mufflers to keep the noise down a bit, about 1.5 feet of stainless 3" downpipe off of the turbo, and a whooooole lot of aluminum tube. When all was said and done, we shaved off close to 40 pounds with the new aluminum exhaust!
- 3.5" 14 gauge aluminum piping
- V-band connections

This downpipe is probably one of the more interesting looking ones that I've made in the past. This customer came to us looking to replace the 2.5" POS he had on his turbo miata with a custom 3" piece. We grabbed an un-divided flanged for his t-28 powered beast and went to work

Lastly, I'll give you guys a peek at our new Evo X OEM replacement manifold. Chopped, welded, and ported all in house












I'll state this again, I am in no way trying to generate sales with this thread. If you are interested in any of the services we offer, or would like to ask about pricing, there is a convenient private message feature that I'm fairly certain is built into this site

I hope you guys enjoy the eye candy! I'll be back posting up more pics and updating this thread as new stuff rolls in, and as cool stuff rolls out

Hey Adam, Finally got some of these parts on and tuned.

Looks like you folks are having fun as always! I wish I lived closer to you folks.

I need a MAP full v-band rotated kit...

That miata dp is some nice work, how long would a aluminium exhaust last?

not very long. I'll never understand why aluminum exhaust has become so popular in the import scene.

I guess in street applications, sure it might be okay, but why in the world would you be concerned with a few pounds of weight savings on a street car. Is it really going to make that much of a difference during your trip to Starbucks or Blockbuster. In actual racing (not drag racing) aluminum exhaust DOES NOT WORK, especially on forced induction cars.

If you work on your car yourself and remove your exhaust frequently it is extremely convenient to be able to hold your entire exhaust system with one hand. I have made multiple aluminum exhaust systems without an issue over the past few years.

BTW, this is why I roll my eyes when I hear people talk about titanium exhaust too... sigh. Remember that guy who built a titanium turbo manifold for a Honda? I was laughing the whole time.

Fit-up looks real tight and nice welds! Might I suggest back purging your stuff with pure Argon set at 18-25 cfm? You'd need NO filler and your welds will sit flat on the inside and outside as well as being completely penetrated with no inclusions or "sugaring". Looks real sweet man!

Thanks for the replies guys! Thanks for the constructive criticism as well, but everything you have mentioned is already being put into use on different items and products we offer. We have a SWEET regulator for back purging, and I love fusion welding as well! Pie cuts, and some other items are fusion welded with no fill rod, some items need to be backpurged, some need to use different size fill rod, etc... Each project is built a bit differently and has different needs, but long story short, we only use the best practices to build our products.

18-25 cfm ??? Really don't give advice unless you know what you are talking about. If you set any flow gauge to 18-25cfm you would BLOW through a tank of gas in a very short time. 18-25 cfh is the proper measurement and that is only dependent of what material and cup size as well as position and environment.

When we tig weld stainless such as sch10 we set our flow rate to 22 and use a number 7 gas lens.


For back purging 5-10 cfh if that is sufficient. Remember argon is heavy so it sits very low in your piece. We fill long sections with foil to take up the space.
But I'm sure they already know that

Good job sideways. I'm sure you do sanitary welds every day.
