Video Review & Installation

Justin: The Pypes Pype Bomb Cat-Back here is currently one of the most affordable full stainless cat-backs of its kind, available for the '86 to '04 V8 Mustang, while delivering a super aggressive tone thanks to that bullet muffler design. Now, materials will be a combination of both 304 and 409 grade stainless, along with your 2.5-inch mandrel-bent tubing, and of course, these massive 3.5-inch resonated tips.Now, install, according to the site, guys, is gonna get a soft 2 out of 3 wrenches on the difficulty meter here. Take a couple of hours or so to complete from start to finish, as we'll show you later in the video. So, as the name implies, the Pype Bomb is not going to be for the faint of heart. Now, the sound is loud and aggressive, and as you guys heard with our sound clips, will certainly turn more than a few heads. So, going to my patented Wake the Neighbor scale, I have the Pype Bomb coming in at a solid 4 out of 5, still waking up plenty of neighbors even with those stock manifolds and headers in place.Now, if you did plan on switching those out for a set of aftermarket headers, along with a very free-flowing mid-pipe, well then, expect those Wake the Neighbors numbers to shoot up dramatically. But overall, I'm a big fan of the sound and tone coming out of the Pype Bomb, and that's largely shaped here by the twin M80 bullet style mid-mounted mufflers. Now, Pypes actually calls these things mufflers, but as you can see, probably not much muffling going on here thanks to that straight through design, which will, again, contribute to much more bark, along with a much more free-flowing design compared to maybe a traditional chambered muffler design.Now, the rest of the kit is pretty straightforward. Again, you got the 2.5-inch mandrel-bent tubing throughout here, guys, leading into and out of those M80 mufflers, before finally exiting out the rather girthy 3.5-inch resonated tips. These things are gonna act as little megaphones for your two or four valve V8, and look pretty beefy underneath your rear bumper. Now, those tips are gonna be made from premium 304 grade stainless steel, while the rest of the system will pack that 409 grade stainless. So, again, full stainless cat-back construction here for right around that mid to high $400 price point. Certainly awesome, and I would say kind of a rarity in the category.But now let's shift gears and get into the install. And honestly, guys, you're probably gonna just wanna cut off your factory stuff if it is still in place. After that is out of the way, the Pype Bomb will be a very simple bolt-on job. But to give you a better idea of just how exactly things will go down, check out our detailed walkthrough and tool breakdown.Man 1: Tools used for this install, a 3/8ths electric impact gun, a 3/8ths electric ratchet, an exhaust grommet removal tool, an extension, 13, 14, and 15-millimeter deep sockets, a 5-millimeter Allen head, PB B'laster, and a cutting tool. Hey, guys. I'm gonna show you how to install our cat-back exhaust here on our '99 Mustang, but first we're gonna watch a quick uninstall video and then we'll jump right back into the install.Man 2: First up here, we're gonna grab a 15-millimeter deep socket. We're gonna head to the center section of our cat-back and loosen up the factory cat-back where it connects to the cat-pipes. There are two clamps on either side. We have a 15-millimeter nut on both, so let's get all four of these loosened up. Next, I'm gonna use a hanger removal tool. This is gonna make your life a lot easier. And directly on either side of the mufflers toward the rear of the vehicle, there are these hangers going into isolators on the frame. We're gonna pop those guys out.Hanger removal tool will allow you to just pinch them right out. Using some kinda lubricant like WD-40 goes a long way. The cat-back's gonna start falling out now, so you just wanna make sure you have a supporting hand on the other side. Just to make life a little easier here, we're gonna disconnect this tip section. There's a band clamp here. I'm gonna use my 15 socket to loosen those up. All right, so now we can take that off in two pieces here. All right, and then this tip slides right out. All right, from here, we can disconnect the flange on the cat-pipe side, and slide this guy right over the axle. Now we can repeat that on the other side.Man 1: Now that we have our stock exhaust off, the first thing we're gonna do is install our tailpipes. I'm gonna take this, put it up over the axle, get it in our rubber grommet up here, and hang both our tailpipes. Then we'll work our way to the front of the vehicle, get everything where we want it leveled, looking good, and then we'll start tightening stuff up. So now I have our tailpipe up in place, I'm just gonna take it, get it into our rubber grommet in here, push it into place, and that'll hold it up like that. I'm gonna do the same on the opposite side.Next, what we'll do is we'll put our tips on and get our tailpipes up into place. So now what I'm gonna do is take my tip, I'm gonna make sure my pipe stays up in that grommet, slide it in place here. And as you can see, they give you different options here for this rod here that can go up into different brackets. We're gonna use this one here. There's a little Allen head on this side, I think it's a 5-millimeter. So now I'm gonna put it up into place, and get the tailpipe where it's gonna sit. Slide that rod up into this hanger up top here, and push it as far in as I can get it. So now I'm just gonna push the rod in as far as I can get it. I left that Allen head loose. And then what this will do is just hold the tailpipe sort of up into place so we can start our front pieces then. Now you're gonna wanna just repeat this same procedure on the opposite side.So, next, what we're gonna do is put our muffler on. As you can see, I got my two clamps. I'm just gonna snug 'em up so they don't fall off. I'm gonna just slide it over the top of our tailpipe and get it started. I'm gonna let it rest there for now, that'll give us access to start putting our front piece on and lining everything up. Now we're gonna just do the same thing on the opposite side.So, now, I rotated our muffler and got it in place, I just had sat it on earlier, and now I'm gonna stick our lead pipe on. First, what I'm gonna do is slide it into our muffler here and get it in place, and then bring it over, rotate it until I get it up onto our flange here, and that's gonna give me access to spin this and get everything lined up. I'm just gonna have to spin it around a little bit until you get it where it seats flat on the flange here. And that looks like right about it there. I'll slide our hanger on there, make sure everything's lined up. We can rotate our muffler a little bit then. I'm gonna put our clamp back on here. And at this point, you're just gonna wanna eyeball everything and make sure everything's in place. Again, what I look for up here is to make sure the socket flange fits where it's supposed to, and you have your muffler and it's kinda level and straight.Once you get that in place, I'm gonna take the two factory nuts that we took off in the uninstall. I'm just gonna get these two nuts started. I'm gonna take my 14-millimeter on my 3/8ths gun and run these in a little bit. Same with this one. Now I have those tight, we'll work our way back, adjust everything, and tighten up our clamps. Now I'm gonna take my 14-millimeter again on my 3/8ths gun, tighten up this clamp here, and the one in the back.Now, at this point, before I tighten this, I just wanted to make sure you remember, make sure you get your tailpipe where you'll want it before you tighten this clamp because then the tailpipe won't be able to move. I already went back, lined the tailpipe up, it looks good, and I'm gonna tighten these up. Now, you're gonna wanna repeat this whole front pipe install and tightening the clamps and adjusting your tailpipe on the opposite side.So now we're gonna go up here and tighten up our tip. It's a 13-millimeter on my 3/8ths ratchet. I'm just gonna get up in here and ratchet this tight. Now, you wanna make sure you got your tip where you want it before you tighten that up. And then up in here on this bracket, there's a little 5-millimeter Allen head. I have the Allen head wrench here, I'm just gonna get up here and tighten that one up. And then you're just gonna wanna repeat this whole installation procedure on the opposite side.That wraps up this review and install of our Pypes Pype Bomb Cat-Back Exhaust with Polished Tips for '86 GT, '86 to '93 LXs, '94 to '04 GTs, Mach 1 and Bullet Mustangs.
