      So the Pypes Mid Muffler Cat-Back we're looking at today is for all 2011 through 2014 Mustang V6 owners. And it's gonna be a good option for someone that's looking for a big increase in volume out back while sticking to a tight budget. Now this will be one of the most affordable stainless steel cat-backs that offers a big boost in volume that's gonna be thanks to the straight-through M80 race mufflers. And like most if not all cat-backs or axle-backs, this isn't gonna take that much effort to get on. And you're looking at a straightforward one out of three wrenches on our difficulty meter here, about a two-hour job. And I will have more for you coming up on that later.So what you just heard in our sound clip is a strong four to five on the loud meter, so you're just shy of a really extreme set-up. Now with any exhaust out there, you can always go louder, but it's tough to get quieter. And what I really like about this is that it's a really great place to find that sweet spot or middle ground. So if you wanted to make the jump and go full core press, you can pick up a Pypes X-Pipe for just over $100, where you'd then be looking at a full five out of five. And that's still plenty more affordable than many other out-of-the-box exhausts with that level of volume. The system's pipes are primarily 409 stainless which is gonna help keep the price down. While they're not 304 stainless, they'll still hold up to rain and snow, but you might see some surface rust after a little while. Now keep in mind that it's something where no one's really gonna see this because it is gonna be under the car, and I wouldn't be too concerned about that. The 4-inch polished tips are made out of a 304 stainless, so they're always gonna be looking great. And moving forward or to the back, depending on how you're looking at it, we'll see the M80 mufflers used here are gonna be a 304 stainless steel as well. And they use a stainless steel mesh inside of a louvered tube that's packed with basalt insulation. Now basalt is said to manage sound better than a fiberglass, so you'll enjoy a deeper and more rich tone, which is gonna be important for the V6. So like I said earlier, this exhaust is one of the most affordable in the category. And at just around $500, you're getting a full stainless, a nice muffler, and plenty of volume with the ability to crank it up to a five out of five for just a few bucks more, and it's really a no-brainer. Now installation-wise, cat-backs go on with little to no effort at all, which makes them a great contender in my opinion. And you should expect a straightforward two hours' worth of wrenching, which is going to warrant an easy one out of three wrenches on our difficulty meter here.Now the tools required for the job will call for a pair of jack stands, a basic socket set, maybe some penetrating oil to hit your factory hangers. So you'll wanna start by getting your car's rear end off the ground. Then work with unbolting the existing system from directly behind your factory mid-pipe. So moving on, you'll get to the back of the car. Remove the axle-back portion of the system and then start back at the mid-pipe. Throw your mufflers in place, tighten down your intermediary piping, get your over axles in place, and then you're good to go.So that'll wrap up my quick review of Pypes Mid Muffler Cat-Back fitting the 2011 through 2014 V6.
