If you're looking for a new exhaust for yamaha grizzly 700, you probably already know that the stock set up leaves a little bit to be desired. Don't misunderstand me, Yamaha constructed a wonderful machine that's basically the gold standard for utility ATVs, but that stock muffler is large, quiet, and honestly, a little bit choked upward. It's designed to meet each and every noise and emission rules on the planet, that is fine for some, but in the event that you want your own Grizzly to really seem like a 700cc single-cylinder beast, an upgrade is almost mandatory.
Replacing out the exhaust isn't just about making noise, even though. It's one of those rare mods where you in fact get a few various benefits all in once. You're getting rid of weight, improving the throttle response, plus giving the bike a personality that matches how it looks. Plus, let's be real, there is certainly something incredibly rewarding about hearing that deep "thump" every time you crack the particular throttle open on a muddy trail.
Why Even Trouble Replacing the Stock Exhaust?
You might be wondering if it's really worth the few hundred dollars to change something that technically works just fine. The share exhaust on the Grizzly 700 will be built just like a tank—and it weighs about as much as one. Most manufacturing plant silencers use the series of internal baffles and large steel plating to keep things quiet. While that's great for sneaking up on deer, it's not great for airflow.
When you switch to an aftermarket exhaust for yamaha grizzly 700 , you're usually moving to a straight-through design with some sort of packaging material. This enables the engine in order to breathe much even more freely. Since an engine is essentially just a big air pump, the easier it can obtain the spent gases out, the faster it may draw the fresh air flow and fuel in. You'll notice the difference most within the mid-range—right where you need this when you're rising a steep slope or trying to pop the front tires over a decreased log.
Then there's the excess weight factor. A common stock muffler may weigh up to twelve to 15 lbs. A high-quality lightweight aluminum or stainless steel aftermarket slip-on can trim that weight in fifty percent. It may not sound like much upon a 700-pound quad, but removing pounds from the quite back and high upward on the frame actually helps along with the entire balance and flickability of the particular machine.
Slip-On vs. Full System: Which One Is usually for You?
When you start shopping, you're going to see two main options: slip-ons and full systems. If you're an informal trail rider or even use your Grizzly for work close to the property, the slip-on will be probably all you need. It supercedes just the muffler and connects for your factory head pipe. It's cheaper, method easier to install (usually about a 20-minute job), plus gives you 90% of the audio improvement people are looking for.
A full system , on the other hand, replaces every thing from the engine block back. This contains a brand new, larger-diameter mind pipe. These are great if you're chasing every single oz of horsepower or if you've currently done other mods like an consumption or a high-compression piston. Just keep in mind that a full system generally needs a bit even more mechanical "know-how" in order to install and almost always requires the fuel controller in order to keep the engine from running too lean.
The Sound Factor: Loud Isn't Always Better
We've all already been there—out on the trails, enjoying the woods, and instantly someone on the quad that sounds like a fighter jet scream-passes you. It's bad, right? When selecting an exhaust for yamaha grizzly 700 , you have to consider where a person ride.
Many aftermarket piping come with "quiet cores" or "silent inserts. " I highly recommend looking for these. The good exhaust should have a deep, throaty growl, but it shouldn't be therefore loud that this gives you a head ache after an hour of riding. Furthermore, if you trip on public lands or in condition parks, you need a spark arrestor . Most quality auto aftermarket exhausts come with one pre-installed or even at least offer you it as an add-on. Without it, you're not just a fire risk in dry brush, but you're also a magnet for a hefty fine from the park ranger.
Do You Need a Fuel Control?
This is the large question that everyone asks. If you simply put a slip-on exhaust for yamaha grizzly 700 and keep your stock air filter, you are able to usually get away without a gas controller. The Grizzly's ECU has a tiny bit of "room" to adjust for minor changes.
However, if you obtain a high-flow exhaust and a high-flow air filter, you're definitely going to be running lean. When a good engine runs lean, it runs very hot, and that can lead to popped valves or a melted piston as time passes. If you notice your new exhaust is glowing cherry red or the bike is swallowing like crazy on deceleration (decel-pop), it's period to buy a gas programmer. It'll help you dial in the air-fuel ratio, and honestly, it's the only method to actually "feel" the ability gains the exhaust is intended to provide.
Materials Matter: Stainless-steel vs. Aluminum
Most exhausts you'll find are produced from 1 of 2 materials. Aluminum is the most typical for the muffler "can" because it's incredibly light plus stays relatively awesome. However, aluminum is usually softer. If you're a rock crawler or you spend a lot of time within tight, technical woods where you might back again into a forest or a stone, aluminum can dent or crack easier.
Stainless metal is the "set this and forget it" choice. It's the bit heavier compared to aluminum but much more durable plus resistant to corrosion. If you ride within muddy or salty conditions, stainless-steel won't look "weathered" simply because quickly. Some high end brands even offer titanium, which will be the very best of each worlds—light and strong—but you'll definitely pay out a premium for that.
Maintaining Your New Exhaust
People often overlook that aftermarket exhausts require a little bit of like. Unlike your share muffler, which is a covered metal box, nearly all performance pipes are stuffed with fiberglass packing. Over time, that packing burns up, blows out there, or gets soaked with water and mud.
When the packing goes, the exhaust will get way louder, the tone gets "tinny, " and a person actually start dropping power since the backpressure changes. Most manufacturers recommend repacking every single 50 to 100 hours of using. It's an unpleasant job, but it's cheap and maintains your Grizzly sounding like it did the day you installed the tube.
Making the Final Call
At the end of the day, picking an exhaust for yamaha grizzly 700 arrives down to what you would like out of your ride. If you prefer a little bit more bark and a lighter machine, a simple aluminum slip-on is the way to go. If you're creating a mud-bogging monster or a cross-country racer, go for the full system and a fuel tuner.
Just remember to respect the trails and the people around you. A Grizzly that seems powerful is amazing; a Grizzly that seems like a broken lawnmower at 110 decibels is simply a nuisance. Find that middle ground, get it installed, and go enjoy the extra "oomph" next period you're out within the dirt. You'll probably find yourself smiling a lot more every time you hit the particular gas.
