Enhance Your EcoBoost Exhaust! Mishimoto Cat-Back Exhaust R&D!

[Mishimoto]

This looks promising. I also dont really want to increase noise levels with an exhaust. Looking for a little better performance and maybe a different sound without the drawback of the loud sound.

Thanks for the input! We want the noise increases to occur under heavy throttle only. Sound volume during normal driving and idling should remain fairly similar to stock. This is the goal with our final design. :cheers:

ok so...does anyone else want the first prototype as desperately as i do???? I like the idea of more power with stock sound. The stock is as loud as I want to go with it. Maybe you can sell various versions mishimoto, pleeeeeeease!!!!

I really like the direction this is going. I don't dislike my current exhaust but for a DD, it booms a bit much. It may be for sale soon though. I'm still loving my intake from you guys. Great quality.

Make sure there is footage inside and outside, as well as driving.

Also, it would be helpful to have a stock intake on to hear the exhaust clearly (without intake/turbo noise interfering).

looking forward to it

Thanks for the input! Don't worry, we will not be developing an absurdly loud setup. This one will be refined and quiet enough for daily use.

We are currently working on our tip selection and fabrication. More on that coming soon!

You got it! Good point regarding the intake. Our intake system can be quite loud and may impact the sound produced within the video. I will mention this to our team to be sure the final product is effective at presenting the CBE in the most accurate fashion.

Thanks

If I may, could you also add a clip comparing the exhaust with and without your down pipe? I too am over having a loud car for every day driving and would like as quiet an exhaust as possible while still making power.

Sure can! We already have some footage from within the shop with this particular setup. One-road testing should produce some nicer sound clips for comparison.

Thanks for the input!

But where is the sounds clip ;)

On the way soon! Thanks for the interest. :cheers:

Another project update!

Enhance Your EcoBoost Exhaust! Cat-Back Development, Part 4: Tip Fabrication

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!

Tip Design

We’ve gone with an appealing tip design for our EcoBoost Mustang exhaust system. Check out a few shots prior to mating this with the rest of our system.

These tips are constructed from polished, double-wall stainless steel and measure 4.5” in diameter. Internally, this diameter narrows to 2.5” to mate with our exhaust piping.

Here is a look at the tips mocked into place prior to fabrication. They look quite nice!

Tip Fabrication

Time to mate these tips with our existing cat-back setup. We made a couple minor adjustments to the piping and muffler location to accommodate the length of the tip. Nothing our experienced team could not handle!

First, we cut off the existing tip on our muffler.

We then constructed a component that would orient the tips properly. This required some measuring and tweaking until the placement was perfect.

We then placed this piece into position and tacked it to the vehicle.

In addition to the modifications post-muffler, we also made a few adjustments pre-muffler for fitment of the tip. Once again, the modifications were small components and were quickly tacked into place.

Mike then set to work at the welding table and fully welded our final prototype.

Coming Up!

The important part is coming! Our video team is gearing up to film this exhaust during some on-road testing. We will be collecting sound clips at idle, acceleration, highway cruising, and during a high-rpm pull. These clips will provide a clear depiction of how this exhaust sounds!

Thanks for reading!

Can't wait to hear it! Looks nice!

Going to offer the ability to have black or burned tips? Maybe as a custom option with some wait time?

 

[Spoolin]

From the pics i cant really tell thier oval, which should be a good thing lol. Cant wait to hear a clip and get pricing.

Our first batch will likely feature only the stainless tip option. We can consider expanding this to alternate options in the future, the door is open for recommendations!

Thanks! I just took the car for a spin and I am really impressed with the setup. The tone is certainly deeper, however it is nowhere near what I would consider loud. Our video crew is out capturing some cool footage now, hopefully we have an awesome video for you soon!

Thanks for following our progress!
