In our last post, we took a look at the axleback fabrication process. Now that our prototypes are on the GT and ready to rock, it is on to testing! While we were not expecting much in the power department out of these exhaust options, we still wanted to see how they sound on the dyno.

Last time we wrapped up our resonator-delete testing, and with that component good to go, we're on to our next conquest, axleback exhausts. If you have not had a chance to take a look at our resonator deletes check out our blog posts HERE.
Axleback Fabrication
Any living, breathing car enthusiast knows that the exhaust is an important modification for modern muscle. Most owners want to rid themselves of the stock sound and let their pony car be heard right out of the gate. Being s550 owners ourselves, we want to hear the unrestricted growl of the Coyote in our GT, so we set out to design some axlebacks. We intend to design a few options as we want to offer an exhaust for every taste. We plan to test a straight-pipe option for those who want to hear the GT scream, a small-muffler option for those who want an aggressive note but have neighbors, and a large-muffler option for those who like
In our last post, we wrapped up the fabrication of our X- and H-pipes. Now that we have some excellent looking prototypes, it is time to put them to the test. We are not expecting much in the way of power with this modification; however we still want to give these resonator deletes the rundown for sound benefit.

Testing
In addition to testing for any power increase we may see with our resonator delete, we will be testing our three different X-pipe designs to determine which one we will proceed with.
Last time we took a look at what went into creating the jig for our Mustang H-pipe. This same process will be applied to create a jig for our Mustang X-pipe designs. We have plans laid out to create three different X-pipe designs to test on the Mustang GT.
It is interesting that the same jig will be used for each of the three X-pipe designs. This is possible because the section that is changing between each X-pipe is the actual X in the center of the pipe. The jig's job is to ensure that the piping coming both into and out of the X itself will fit with the rest of the Mustang GT exhaust system. The center design is unrestricted by the jig, and therefore we have some room to play with the design.
We plan to create different degree bends for the X part of the pipe: a 60° X-pipe, a 45° X-pipe, and a 20° X-pipe. We will test these three designs to see if there is any benefit to using these various X designs on our GT.
But first fabrication! After the piping was laid
After coming up with a game plan we were ready to tackle the first portion of the Mustang GT exhaust, the resonator. We began this exhaust project a bit differently than projects in the past, we began with the waterjet.
How, you might ask, are we going to produce a prototype made of piping on the waterjet? We're not! To save time and improve accuracy, we will use a jig to create the first prototype H-pipe and X-pipes. Our hopes are that they will provide more precise prototypes that need less revision, therefore saving time. We will also use the same jig for production, so that each resonator delete produced will have the same great fitment as the prototype that we create.
With that said, we fired up the waterjet and began cutting our jig.

At Mishimoto, our job is to bring you more than just exceptional cooling products. Another product category that we offer is exhausts, and what better car for an exhaust project than the fantastic-sounding Mustang GT!
The stock system on the Mustang GT sounds pretty darn good as is, but after inspection we found some ways that we could improve on the stock design. If you aren't familiar, here are some photos of the stock Mustang GT exhaust.
