2015+ Ford Mustang Ecoboost

With just a couple small tasks to go, we’re near the completion of this 2015 Mustang cat-back exhaust project. Our design for this system is complete from the downpipe connection to the end of the stainless exhaust tips.

3D Models

Our prototype exhaust meets our requirements for both fitment and performance, so it was time to create a 3D-model of our design, which would ensure that our manufactured exhausts match our design exactly. After some time at the computer screen working in Solidworks, we ended up with the awesome renderings below!

We’ve logged some miles (and smiles) during the testing of our two cat-back exhaust setups. We’ve decided on a strategy for the muffler selection, one that we feel best suits the tones of the Mustang EcoBoost (EB). Our team determined that the round muffler setup is just a touch too loud, and that the oval mufflers shown in the previous segment provided the exact sound we are seeking. Months of tedious design and testing have resulted in drone-less operation on the highway, improved volume at wide-open-throttle( WOT), and stock-like sounds during light/partial throttle.

I am sure you guys are eager for some final sound clips, but you will have to wait just a bit longer. In the meantime, we’ve settled on the muffler tip we will be using, and we’ve fitted it to our final prototype. Check out the process below!

We’re back with another prototype! After fitting our first unit, we found a few areas of our design that required minor adjustments to fulfill our goals of perfect fitment and optimal heat transfer. Our new 2015 Mustang EcoBoost parts are nearly complete!

Final Prototype

As noted in our previous article regarding the EcoBoost Mustang (EBM) radiator, we wanted to make modifications to both the core and our lower mounting brackets. These were easy changes, and we now have the second prototype shown below!

It has been ages since we’ve had an update on our EBM aluminum radiator, and for good reason. Our team has been hard at work putting together a functional prototype for some initial test fitting. We used dimensions from the stock base model radiator, the performance package radiator, as well as measurements from the vehicle to ensure our prototype would fit and function with all factory components. Our line of 2015 Mustang EcoBoost parts is continually growing and we are looking forward to offering a full cooling package.

First Prototype Unit

After making several tweaks to our 2015 Mustang radiator design for fitment purposes, we finally had a complete design that could be d

The search continues to find the optimal blend between a high-quality WOT (wide-open throttle) exhaust sound and a rich sound during normal driving and light-throttle driving situations. In this segment, we continue with our 2015 Mustang exhaust sound testing to see if we find our second or third prototype setup pleasing.

Dyno Testing

We set up our EB on the Dynapack for some more sound collection. We also kept an eye on power output and AFR readings to see if power changed on the factory tune, and to see if the improved flow would impact AFRs in any way. On our 2015 WRX, we saw these readings lean out a bit with the cat-back installed, so we wanted to see if this was the case with the 2.3L!

First Prototype: Sound

We’re starting this article with a recap of Part 1 of this series, which highlighted our first prototype for the 2015 Mustang EcoBoost exhaust design. If you recall, this design featured a midmuffler as well as two rear mufflers.

We promised a sound clip of our first design, so check it out below!

As you can hear, this setup is not quite what we are looking for. Although our mufflers are more free-flowing compared to the stock units, the sound of the EcoBoost is still stifled quite a bit. In fact, actual noise increases over the stock exhaust setup are minimal and nearly unidentifiable.

We needed to make some modifications to create a more prominent sound. Back to the drawing board!

Prototype 2 Plans

This project is turning out to be quite an experimental process. We had planned to try numerous different configurations until we attain an optimal s

If you follow any of the product development going on here at Mishimoto, you should have noticed our recent concentration on the Ford Mustang EcoBoost. So far we’ve developed, tested, and perfected a variety of awesome new components, including the list below.

• Performance Intake System
• Direct-Fit Catch Can
• Direct-Fit Oil Cooler
• Baffled Coolant Expansion Tank (still in the works)
• Downpipe (still in the works)
• Radiator (still in the works)
• Intercooler
• Intercooler Pipes

After putting some final touches on our pipe design in 3D modeling software, we concluded the design phase of this project. With only inspection of our final prototype and final test fitting on the agenda, this project was nearly complete.

3D Pipe Models

As with all our projects, we would be using 3D modeling software (Solidworks) to put our final design into both 3D and drawing forms. Not only does this put our design into a viewable format, but it also allows for digital tweaks as well as confirmation of fitment and precision with the overall product design.
