Hey there, fellow gearheads! Are you looking to seriously upgrade your 2023 Toyota GR86? Then you've probably been eyeing a catback exhaust system. And for a good reason! Swapping out your factory exhaust with a performance catback is one of the easiest and most effective ways to boost horsepower, torque, and, let's be honest, that all-important exhaust note. But with so many options out there, how do you choose the perfect catback for your GR86? Don't sweat it, guys, we're here to break it all down for you.

Why Upgrade Your GR86 Exhaust?

Okay, so why bother with a catback exhaust in the first place? Here's the lowdown:

• Performance Boost: The stock exhaust system on the GR86, while decent, is designed with restrictions to keep noise levels down and meet emissions regulations. A performance catback exhaust is engineered with wider diameter piping and less restrictive mufflers and resonators. This allows exhaust gases to flow more freely, reducing backpressure and freeing up horsepower and torque. Expect to see gains in the 5-15 horsepower range, depending on the system. That might not sound like a ton, but you'll definitely feel the difference in throttle response and overall acceleration.
• Aggressive Sound: Let's be real, the sound is a huge part of the fun! A catback exhaust transforms the GR86's exhaust note from a mild purr to a throaty roar. You'll get a deeper, more aggressive sound at idle and a satisfying growl under acceleration. Just be mindful of noise regulations in your area – you don't want to attract unwanted attention.
• Weight Reduction: Many aftermarket catback exhausts are made from stainless steel or titanium, which are significantly lighter than the factory exhaust system. This weight reduction can improve handling and overall performance, even if only slightly. Every little bit counts, right?
• Enhanced Aesthetics: A new exhaust system can seriously improve the look of your GR86's rear end. Many catback systems come with polished stainless steel tips or burnt titanium tips, which add a touch of style and aggression. Plus, a clean, aftermarket exhaust just looks way cooler than the stock one.

What to Look for in a GR86 Catback Exhaust

Alright, so you're sold on the idea of a catback exhaust. Now, let's talk about what to look for when choosing the right one for your 2023 GR86:

• Material:
  • Stainless Steel: This is the most common material for aftermarket exhausts. It's durable, corrosion-resistant, and relatively affordable. Look for 304 stainless steel for the best quality and longevity.
  • Titanium: Titanium is the ultimate exhaust material. It's incredibly strong, lightweight, and corrosion-resistant. However, it's also significantly more expensive than stainless steel. If you're looking for the absolute best performance and weight reduction, titanium is the way to go.
• Piping Diameter: The diameter of the exhaust piping plays a crucial role in performance. Most aftermarket catback exhausts for the GR86 will feature 2.5-inch or 3-inch piping. A 2.5-inch system is a good choice for those who want a balance of performance and sound, while a 3-inch system will offer the best possible performance but may be a bit louder. If you plan on doing serious modifications, like forced induction (turbo or supercharger) in the future, a 3-inch exhaust is definitely recommended.
• Muffler and Resonator Design: The design of the muffler and resonator will determine the sound of the exhaust. Some systems feature straight-through mufflers for maximum flow and a loud, aggressive sound, while others use chambered mufflers to reduce noise and drone. Resonators help to eliminate unwanted frequencies and create a smoother, more refined exhaust note. Pay attention to the manufacturer's description of the sound characteristics to find a system that suits your taste.
• Fitment: This is critical. Make sure the catback exhaust is specifically designed for the 2023 Toyota GR86. A poorly fitting exhaust can cause leaks, vibrations, and other problems. Read reviews and check for feedback from other GR86 owners to ensure proper fitment.
• Brand Reputation: Stick with reputable brands that have a proven track record of producing high-quality exhaust systems. Some popular brands for the GR86 include Borla, Invidia, Remark, and HKS. These companies have invested heavily in research and development to ensure their products deliver optimal performance and sound.

Installation: DIY or Professional?

So, you've picked out your dream catback exhaust. Now, the question is: should you install it yourself, or should you take it to a professional? The answer depends on your mechanical skills and comfort level.

If you're comfortable working on cars and have some basic tools, you can definitely install a catback exhaust yourself. It's a relatively straightforward process that typically involves unbolting the old exhaust system and bolting on the new one. However, you'll need to make sure you have the right tools, including a socket set, wrenches, and a jack. You'll also need to be careful not to damage any of the surrounding components.

If you're not comfortable working on cars, or if you don't have the necessary tools, it's best to take your GR86 to a professional mechanic. They'll have the experience and expertise to install the exhaust system correctly and ensure that it's properly aligned. The cost of professional installation will vary depending on the shop, but it's typically in the $100-$300 range.
