Exhaust Design
 

The previous generations of the Mustangs were designed with the mufflers located under the cabin. The newer (05-13), have them located under the trunk area. Being that the setups are a touch different, does anyone know if there is a difference in performance (back pressure etc.) I am considering having a custom exhaust built and prefer that the mufflers be placed where the resonators are located. This is on a 2013. I am also curious how different the sound would be...Can anyone shed some light on this?

Thanks!

Is there enough room for a full size muffler there? I know the resonators are basically side by side before they go over the axle, so unless you are doing a simple flow-through/glass pack setup, I don't think it's doable.

And just fwiw, I'm pretty sure the older gen mustangs, at least 99-04, had the exhaust under the trunk pretty much, at least my friend's V6 does...I know the Cobra didn't because of the IRS

Well, i dont plan on using a full size muffler. My thoughts were to go with a simple Twister or Bullett. Given the size of a Bullett, they should fit perfect considering they arent much larger than the resonator.

As far as the older gen's, (94-04), the mufflers were more centrally located. My 04 had a Dr Gas Catless X-pipe and a Bassani catback. Those catbacks were designed with the muffler before the axle.

I don't see a problem with running that type of setup then.

Curious how it will sound with a little more pipe behind the muffler vs the stock style setups. should give it a nice deeper tone with less burble.

Appt to get it built the Monday after Thanksgiving weekend. Anxious to hear it myself!

I ran a similar setup on my 2007 GT and it sounded good. Had magnapacks installed right in front of the axle.

Cool! Glad to hear that. I wanted to go a bit unconventional.

There isn't enough room to fit a full size muffler there. A bullet style will fit no problem. Pypes offer a catback with that design. And actually they sound pretty good on these new 5.0 cars.

Sounds good, but I'm getting the x-pipe built at the same time and I'm not spending anywhere remotely close to list price. I appreciate you providing that link though! Essentially, the setup will be a 3 in x-pipe, Moroso Spintecs in place of the resonators (very comparable to the Pypes setup you just showed me) all in installed. A good friend of mine has been fabricating cars for years and has done the majority of the work on all of my previous vehicles.

Mind me asking where his exhaust shop is? I need to get my over-axle pipe realigned.

Side question, but why are people replacing the resonators with other bullet type mufflers? Is this to change the tone and/or volume or what?

I think the tone would change a little bit having more pipe volume after the muffler. Less rasp probably.

That would be nice. These mods motors really like to make popping noises which can be a lil annoying.
