CJ Pony Parts has an exclusive part for your 2015-2021 GT Mustang, the Magnaflow 1004384 Clamp-In Stainless Steel Tru-X Resonated X-Pipe is only available right here!

If you are running long tube headers, muffler deletes or an aggressive axle-back, this Clamp-In Stainless Steel Tru-X Resonated X-Pipe from Magnaflow is for you. Deleting your factory resonator will add potentially unwanted gains to your volume and raspiness. The only option to avoid that unwanted noise was to pay an exhaust shop to fabricate and weld up something that was not a modular solution, but not anymore. Now you can achieve that x-pipe sound, increase flow, maintain a deep tone and not add additional raspiness with Magnaflow's Clamp-In Stainless Steel Tru-X Resonated X-Pipe.

This exclusive Clamp-In Stainless Steel Tru-X Resonated X-Pipe from Magnaflow is constructed of 100 percent 409 stainless steel. To deliver a smooth, deep tone, stainless mesh wrap and acoustical fiber fill are utilized. In an effort to ensure that smooth, deep tone you are looking for does not diminish over time this X-Pipe is packed to the gills with acoustic fiber fill. The dual intakes measure in at 2-1/4 inches and the corresponding outputs measure in at 2-1/2 inches to maintain the free-flow straight-through the perforated stainless steel core.

If you have already paired a resonator delete with your long tube headers, muffler deletes or aggressive axle-backs and you want to tame it down a bit without sacrificing that deep tone this exclusive, resonated X-Pipe is your solution. Don't reinstall your factory resonator or have an exhaust shop weld something up when this new X-Pipe will solve your problem without breaking the bank or undoing your performance upgrades.

Designed and engineered to share the same mounting locations and dimensions of the most popular and largest resonator delete, this Magnaflow 1004384 Clamp-In Stainless Steel Tru-X Resonated X-Pipe is a direct swap for anyone that already has that resonator delete installed. If your current resonator delete in not an exact swap for this exclusive X-pipe a simple trim off of your existing tailpipe will give you all the room you need to complete the clamp-in installation. This cut and clamp installation requires no welding and this exclusive X-pipe comes with the required clamps.

A resonator delete has become one of the most popular modifications to the S550 Mustang. The factory resonator is very heavy and very restrictive, so deleting it is a great way to add some sound and shave some weight from your car. The problem a lot of people have, including ourselves with our 2015 GT, is when you go to a really aggressive muffler, sometimes it's just too loud with a resonator deleted. If that's the case, now we're going to offer this MagnaFlow Tru-X resonator, which will fit all 2015 through 2017 Mustang GTs.

This MagnaFlow Tru-X resonated exit pipe will be a direct replacement for the factory resonator on your 2015 through 2017 Mustang GT. It features an internal X design to provide plenty of flow and a very good sound, as well. For this installation, we'll need a lift or a jack and jack stands, 3/8" ratchet, 15 millimeter socket, file, sawzall, and safety glasses.

Here you can see the factory resonator. Like I said, it's very heavy, and it's very restrictive. The MagnaFlow is going to replace it. You'll notice the one end has a little kick out here. That's going to go on the passenger's side. What you're going to want to do is basically hold it up, line it up in the middle of these front clamps here, and then we'll mark the back for where we're going to cut. We have the MagnaFlow pipe up into place, lined up in the front, and again, you can see back here. What you're going to want to do is you want to get a cut right in this area here. Basically just like the width of your finger past this curve, and we're going to cut both pipes off.

All right, with the resonator cut now, the tail pipe to remove it, you're going to loosen these four nuts here to remove the clamps. Before we install our new pipe, we're just going to clean up our cuts a little bit, make sure there's nothing sticking out so the pipe fits cleanly. We're going to put the clamps on first, and we're also going to take the clamps off the front here and put them on, as well. Then slide it over the pipes. All right, if I can get it straight, I'm going to push it up into place, and slide the clamps over the front pipes.

All right, now, once you've adjusted everything, you can tighten up the rear clamps, then re-tighten the front. All right, double check and make sure everything is tight, and make sure the tips are aligned properly, and your installation is finished. All right, now the part everyone is waiting for, let's see how it sounds.

The MagnaFlow Tru-X high flow resonator really fills a nice void in the S550 market. If your Mustang is a little bit too loud with the resonator deleted or too loud for your neighbors, it's a great way to get rid of the sound and bring it down a little bit, and it also gets rid of a lot of the raspy sound, as well. The installation is pretty straightforward. It'll take you about an hour to an hour and a half. You should be back on the road in no time.
