This exhaust will run about 6,000 ft with less trouble. Even if you went from a stock 158 jet to a 165, it will run great. The performance of this thin pipe is highly noticeable with the improvement in power and torque during the long trip. 

Features with Benefits

Let us move and discuss some of its feature benefits. However, it has very few advantages, compared to others. 

Sounds Good 

The staff is highly remarkable for making fewer sounds. Making weird sounds is a common characteristic of the exhaust. But this pipe is freed from these functions. It’s very comfortable to use and operate. 

Provide More Power 

The silver slip pipe is master to provide more power during the trip. This feature seems to be very rare on some exhaust. But this time, the big gun silver tool can provide and increase the power automatically. 

The tool is made only to realize four things- provide power, sounds, craftsmanship, and performance. The crafting style of such a tool is really impressive as it can produce more power. Nothing is cooler like this, whereas you go out on long drives. 

Comes With Brush Aluminum Muffler

The eco series exhaust is more durable than others. The stainless-steel tubing is the common coating that we find in almost every component. But the main variation occurred when we learned that the pipe has 6061 brushed aluminum muffler canisters. This is a proven material that will last for many years. 


  • Fits on Yamaha YFZ 450 (04-09)
  • Lightweight
  • Able to deliver maximum power

2. Big Gun 09-24602 Titanium Size Exhaust | Best sounding exhaust


Check Price & Photos on Amazon

Quick Specs

  • Item weight- 7.5 pounds
  • Dimensions – 45×7.5×6.5″- inches
  • Material – Red powder coated stainless steel

This header pipe originally would not fit the mid-pipe, so you may get upset about this. But you may get impressed with the power gains from the exhaust system that it produces. It sounds killer and will snap up on a wheelie from a bog in third gear.

You can use this dynojet stage two jet kit that comes with a pile of pilot choices. This tool is used to develop the altitude. You can also use the 48 pilots with 165 main and the custom tapered needle in the 5th setting. We wouldn’t recommend you use stage 3 unless it has a cam upgrade, which can mess up.

Anyway, this is a fantastic pipe setup except for the minor fit issue. You can race and ride by using this for many years. 

Features with Benefits

There are some major benefits we’ve found on this stuff that are unique and good. These are, 

Deliver Maximum Horsepower

The staff will provide you with maximum horsepower. It is also able to give you enough torque power to run the engine more smoothly. The components are required to spread the power evenly in the rpm range. 

Made With Solid Materials 

With the absence of solid materials, the longevity of your exhaust isn’t recognized. Fortunately, this crystal pipe will come with 049 stainless steel tubing. Also, it is a strong base of an aluminum muffler canister. Along with this, the EVO exhaust system is much lighter compared to the stock units. 

Heat Resist

The sleek muffler design of this stuff will allow maximum clearance to prevent exhaust from bursting.

Overheating is another reason by which your stuff can get damaged. In that case, the big gun titanium exhaust is fully heated resistant to give extra protection. 

Fits On Different Models

If you’re buying any exhaust, fitting with the vehicle will provide you with the certainty that it will go throughout. Hence, this item fits different upgraded models. Likewise, 

  • 2004-2009 Yamaha yfz450

However, the exhausts are used only for closed courses and not permitted for use on the road. It’s just because most of them are not legal for sale or use on pollution-controlled vehicles. This sort of exhaust is hardly found in the state of California.

Hassle-Free Performances 

This sparks racing X6 exhaust system is ideal for any application. Due to the power gains, it will be able to produce through the entire power curve. You can call it the best exhaust yfz450r

The model comes with a complete system, not a slip-on, as it could perform well on an incomplete system. 

So far, it works much better. That’s why you may find it more profitable than working with the limitations of the stock head pipe. 

It has been proven that this model is worthy of beating the Pro-level riders. Similarly, it could be dragging the races. The model is eligible to compete in high mileage competitions for best performances. 

Offers X6 & X6 Big Cores

The product is eligible to fit in both X6 and X6 big core systems. The X6 race core can compete with the 2″-inches outlet diameter. With this diameter, the core will give you certainty for better actions. It is the best exhaust for yfz 450.

On the other hand, both can be configured with two vital pieces of stuff- spark arrestor and quiet inserts. 

120-110db Testing Guidelines 

Both of these racing core systems can be adapted with 120-110 dB testing guidelines. Among them, the race core system uses up to 120db. The big core houses support 2.25″-inches outlet diameter to offer top-end performance. They are resisting to fit on different models. But they’re known as the best exhaust for 06 yfz 450.

Another side, the Big Core is up to 110db using the SAE testing guidelines. But it cannot be configured with any quiet inserts. Hence, you can add the spark arrestor to the Big Core system. Yet, this big core is never intended for using a spark arrestor. 

We must say it’s not too good because this running spark arrestor will drastically shorten the arrestor’s longevity.
