1979-2004 Mustang SLP Loudmouth Center/Center Shotgun Style Resonator Pair – 2.5″ Review


The SLP Loudmouth Shotgun Style Resonators
would be a great choice for any Mustang owner really who is looking to create their own
custom exhaust setup, or more specifically, for the ’79 to 2004 cars using an existing
SLP Exhaust System and and want to replace a damaged resonator or muffler as these will
be a direct fit. Now, SLP does include two hand-polished 304-grade
stainless resonators for right around 160 bucks and the install will vary depending
on your setup. So, let’s just go middle of the road, two
out of three wrenches on the difficulty meter and a couple of hours from start to finish
to be on the safe side. So, right off the bat, I would say the most
popular application for the SLP resonators here will be as an affordable solution to
give your Fox or SN95 a little bit more rumble by cutting out those factory mufflers and
welding these guys into place. That’s very evident in the customer review
and photo section as well as on YouTube where any search of the SLP resonators will immediately
turn up dozens of New Edge GTs sounding off with this particular setup. And I have to admit, guys, I think it sounds
pretty awesome, very deep, very aggressive, even with those factory manifolds and cats
in place and gets just downright dirty with a set of long tubes or an aftermarket mid-pipe. But on the other hand, if you already have
an existing SLP cat-back on your V8-powered Fox or SN, whether it be the Loudmouth or
the Loudmouth II, these will be a direct replacement for the existing resonators if you ever need
to swap them out for whatever reason, maybe you hit something on the road, scraped them
up, whatever the case, this will be an easy and direct swap. Dimensions for the resonators themselves will
be just over 18 inches in total length with a 4-inch body diameter and that will allow
them to be used in some pretty tight spots underneath the car. Inlet and outlet will be both 2.5-inches and
they will be straight through by design, eliminating a big chunk of restriction otherwise caused
by a traditional chambered muffler. Finally, guys, these things are made from
premium 304-grade stainless steel and will be sold in sets of two. As far as your installation is concerned,
well, again, guys, it will go down in one of two different ways. Now, if you’re replacing an existing resonator
or muffler on an SLP cat-back, it’s gonna to be a piece of cake, right? Just simply loosen up the clamps, swap them
out, and you’re good to go. On the other hand, if you do plan on incorporating
these in place of a set of factory mufflers, then there will be some cutting, there will
be some welding involved, which will stretch the time and the difficulty of the job. Because of the differences in install here,
guys, the site’s just gonna go middle of the road two out of three wrenches on the difficulty
meter and a couple of hours from start to finish. But if you’re looking to go custom and create
your own system, or just replace a set of mufflers or resonators on an SLP cat-back,
the Shotgun style resonators here will be an affordable solution and you can grab your
pair right here at americanmuscle.com.
