Key Takeaways

• Slip-ons are more affordable, easier to install, and produce thunderous volume.
• An exhaust system replacement offers better performance gains, but there are potential legal issues.
• Choose slip-ons to increase volume, improve tone, and enjoy a modest performance boost.
• Choose a full replacement if your system is failing or you want significant performance gains.

Slip-on or full exhaust? Here at Boneshakers, we make the industry’s best slip-ons, so it’s clear where we stand.

With that said, we know every road warrior has their own preferences. That’s why we’re going to provide an unbiased guide to the pros and cons of a slip-on exhaust vs. a full exhaust replacement. Let’s roll.

1. Cost of Admission

Before we get into the real nuts and bolts, let’s talk about entry fees. Replacing a full exhaust system isn’t cheap. We’re talking upwards of two grand for some bikes. Slip-ons are significantly less expensive.

With a full system replacement, you’re not just paying for new header pipes, mid-pipes, and mufflers. You’re paying for labor. If you’re an experienced wrencher, you might be able to take the DIY route to save some cash, but it’s still a ton of work and time.

2. Volume

If you’re deciding between a slip-on exhaust vs. a full exhaust replacement, there’s a good chance you’re looking to make more noise. In fact, for many riders, that’s the whole point.

What does a slip-on exhaust do for a motorcycle? It makes your bike the head-turner it deserves to be. Our slip-ons deliver the thunderous volume and rich, clean tone you crave, but at a fraction of the cost of a full replacement.

When choosing between a slip-on exhaust vs. a full system for a motorcycle, consider whether or not you actually need a new system. If your system’s failing, by all means, replace it. But if you just want the road to hear you coming, slip-ons are all you need.

3. Performance

Here’s where the difference between a slip-on exhaust vs. a full exhaust replacement becomes clearer. Upgrading your entire exhaust system can yield significant performance gains, especially if the system’s on its way out.

Most slip-on users report modest performance gains, like an instant throttle response, boosted torque and horsepower, and quicker acceleration. And, because slip-ons tend to be lighter than stock mufflers, they can enhance handling, control, responsiveness, and balance.

We’ll be the first to admit that a full exhaust system replacement typically delivers better performance gains. Our slip-ons are mainly for unleashing the roar. The performance boost is an added bonus.

As you weigh the pros and cons of a slip-on exhaust vs. a full exhaust replacement, think about whether or not you truly need the replacement. If your current system still works, modding it may be the better option.

4. Installation

As mentioned, the price of a slip-on exhaust vs. a full system for a motorcycle includes labor. But cost isn’t everything, and a lot of riders love tinkering with their bikes. If you want to take on a major project, more power to you. 

Obviously, installing slip-ons is quicker and easier than replacing a full system. However, you might not realize just how straightforward the process is. Slip-ons are the perfect starter mod for beginners, and experienced wrenchers appreciate the hassle-free setup, too.

As far as installation goes, the difference between a slip-on exhaust vs. a full exhaust replacement is massive. Our cat-back design uses your bike’s existing mounting points and hardware. All you need is a few basic hand tools to turn your bike into a beast in under an hour.

5. Tuning

After a full motorcycle exhaust system replacement, a full tuning is a must. With slip-ons, we highly recommend an ECU or dyno tuning, but it’s not always mandatory.

Slip-ons improve the bike’s airflow, which naturally alters its air-fuel ratio. Tuning restores the balance so you get the full performance boost.

6. Legality

As you decide between a slip-on exhaust vs. a full exhaust replacement, don’t overlook the law. Don’t let your upgrade put you at risk of steep fines, or worse.

Tampering with emissions-related parts, specifically the catalytic converter, is illegal. That’s why most aftermarket exhaust systems are sold for “competition/race use only.”

With slip-ons, your bike’s catalytic converter isn’t altered, so you won’t run into any emissions-related issues. We recommend checking your local noise ordinances, but as long as you're allowed to get loud, you shouldn’t run into any problems with the law.
