With our first EcoBoost downpipe prototype complete and fitting on the EB perfectly, it was time to perform some product testing. We wanted to do so for two reasons. First, we wanted to see the impact on power output with a tune, our intake, and this new downpipe we developed. We have been watching the progress of the EB HP/TQ race on the forums, and we wanted to see what kind of numbers our car could put down. On top of this, we are also itching to drive this Mustang with a bit more power. Our second purpose for testing this component was to evaluate the sound quality of our 2015 Mustang EcoBoost downpipe once installed.

Dyno Testing

In some related news, we have a new toy to play with in the shop, a Dynapack dyno. We’ve already been testing this unit with our 2015 WRX and so far it is an extremely nice tool for our team. The necessity to test our EcoBoost downpipe provides another excuse to make some pulls and aggravate our office neighbors for the day. Fun!

Of course we caught some of the action on film for your viewing pleasure. Check out the video below for a compilation of our EcoBoost Mustang downpipe testing.

We also swapped downpipes during the test to see if any appreciable power or sound differences were produced with catted and catless setups. Power output was relatively similar, although this was likely a reflection of the tune we were using. It is certainly possible our cat-less setup would provide a slight improvement in output due to increased flow. Sound was essentially identical for both of our 2015 Mustang EcoBoost downpipe options.

Dyno Results

Pretty nice numbers for a few bolt-on modifications. This particular comparison was a completely stock EB against the same vehicle with our downpipe, intake, and a tune. With the modified setup, we saw peak torque of just under 400 very early in the pull, which tapered off until redline. Horsepower does the opposite and eventually peaks just above 305. This results in a peak gain of 22 whp and 118 wtq! Output is going to depend very heavily on the tune in use. This test was simply to ensure flow was sufficient with our design and to put some basic numbers behind what can be achieved with our intake, downpipe, and a quick tune.

The heat produced with testing also tinted our EcoBoost Mustang downpipe slightly, which is normal with stainless steel seeing such temperatures. In fact, it looks pretty slick. Check out a few shots!

Discounted Pre-Sale

We now have a final design that fits well, performs well, and meets all of our expectations. Time to start manufacturing! In the coming weeks we will be running a discounted pre-sale for those interested in picking up a downpipe from our first batch of units.

Check back for more details on pricing and estimated shipping information!

Thanks

    1. Hey Jay,

      Thanks for the interest! We started manufacturing our first batch of downpipes recently, we expect them to be complete and ready to ship around mid-October. In a few weeks, we will be launching a discounted pre-sale for those interested in picking up one of our first kits. The tune was essentially an e-tune in place to test out our system. We will not be offering this tune as a package or component to go with the pipe. Any reputable tuner should be able to put together a tune for you that makes similar, if not better, power gains with our downpipe installed.

      Thanks again!

    1. We are offering both catted and non-catted versions of the pipe. From a visual inspection standpoint, the catalytic converter equipped pipe should pass emissions without issue. Performance based emissions will be dependent upon the tune you have in place. Assuming the tune is safe, you should not run into any issues with emissions testing.

    1. Hi Red,

      We run our testing with the manufacturer recommended consumer-grade fuel. So this test would have been run with 93 octane pump gas.

      Let us know if you have any other questions!

      -Steve

      1. How much lower would those numbers go down on a 91 tune? Significantly or a little bit? I’m asking cuz I just got the Mishimoto down pipe and there’s no 93 octane anywhere in the LA area which is where I live
