Customer Reviews
Customer Review: These don’t sound half bad, good and loud. My 77 C10 still sounds kinda like a old farm tractor at idle but they wake up when you put your foot into it. I changed my exhaust from a Y pipe single exhaust to a X pipe dual exhaust.
Customer Review: Bought this to take the place of a factory resonator which rusted out and started to leak. This fit perfectly in its place. The tone of the exhaust is deeper, with a slight increase in noise over stock, however I still have the oem muffler in place. The Thrush muffler cut out the rasp that I was getting when I had a straight pipe in as a temp fix. This is much better. Hoping the packing will last for several years. Note that your results may vary, a shorter glasspack will be louder, and have a raspier tone than a longer one.

Customer Reviews
Customer Review: I got this 3″ Universal Custom Exhaust Kit for a custom project on my Pathfinder. As someone looking for a cost-effective way to dive into the customized exhaust world, this was a solid starting point.The GoodValue for Money: At under $90 for an 8-piece set, it’s hard to beat the price for a DIYer. It includes a variety of angles, though I personally did not need the U-shape pipes for my specific layout.Bend Quality: The mandrel bends are consistent and didn’t show signs of collapsing or thinning, which is vital for maintaining exhaust flow.Packaging: I was pleasantly surprised by the quality of the packaging; everything arrived well-protected and neatly organized.The Realities of Mild SteelRust Resistance: Be aware that this is 18-gauge mild steel. Mine actually arrived with some pre-rust on the inside of the tubes. If you live in a salt-heavy area, you’ll definitely want to apply a high-temp coating to improve its longevity.Functionality: While it’s marketed as a weld-up kit, the ease of installation is flexible. Since I’m still a beginner, I installed these using a combination of clamps, joints, and a healthy amount of muffler cement to ensure a leak-free seal. It held up well to the “hack and fit” process.VerdictThis is a good kit for a first-timer/beginner who wants to learn the ropes of exhaust routing without spending a fortune on stainless steel. It provides all the necessary ideas and physical pieces to get a custom job done, provided you’re okay with a little extra prep work to manage the mild steel finish.
Customer Review: Pairs of 45, 90, and 180* bends with flared ends give you a nice combination of parts to make any configuration. In the real world, these work best if you’re able to weld, then just cut the bend where you need it, weld it together to get all sorts of angles and directions. The flared ends allow you to slip the ends over other parts to hold them lined up, some might try to use a clamp over them to hold them but they’re really mostly there for ease of fit up and to mate to different sizes you’ll find that things like mufflers and converters will have ends that are flared and not flared to act as inlets and outlets and you need to match up piping, and having a selection of ends on piping helps it all work together.The only negative is that this is just bare steel. Not stainless, not aluminized (some steel tubing will have an aluminized coating to prevent rusting). No coating will mean that it will get surface rust quickly or need to be coated to protect it, but it also means it’s easier to weld.

Complete Buying Guide for Best Exhaust Pipes For Harley Davidson
Essential Factors We Consider
When you’re looking for the best exhaust pipes for your Harley Davidson, it’s more than just picking something shiny. You need to think about several key factors that impact sound, performance, and longevity. First, consider the material: stainless steel offers superior corrosion resistance and durability, while mild steel is more budget-friendly and easier to work with if you’re custom fabricating, but it requires coating to prevent rust. Next, the exhaust design plays a huge role in sound and performance. Two-into-one systems generally offer better performance gains, while true duals give that classic, balanced Harley sound. Slip-ons are an easy sound upgrade, but full systems replace everything for maximum impact. Finally, pay attention to the finish and aesthetics; do you want chrome, black, or a raw finish to complement your bike’s style?
Budget Planning
Upgrading your Harley Davidson exhaust can range from a few hundred dollars for slip-on mufflers to several thousand for a full, high-performance system with tuning. Custom fabrication kits are often more affordable for the parts themselves but require additional investment in tools, welding supplies, and skilled labor if you’re not doing it yourself. Decide on your budget early on, and remember to factor in potential costs for a fuel management system or tuner. A new exhaust might require your bike’s ECU to be remapped to optimize performance and prevent damage, especially with full systems that significantly alter back pressure. Don’t cheap out on the tune; it’s vital for getting the most out of your new pipes!
Final Thoughts
Ultimately, the best exhaust pipes for Harley Davidson riders are a personal choice. It’s a balance of the sound you love, the performance you crave, and the look that completes your bike. Don’t rush the decision. Listen to sound clips, talk to other riders, and consider how the pipes will affect your riding style. Whether you choose a classic glasspack, versatile custom tubing, or a premium stainless steel kit, make sure it resonates with your passion for the ride. Your Harley deserves a voice that’s as unique as you are!
FAQs For Best Harley Davidson Exhaust Pipes
Q: Do I need to re-tune my Harley Davidson after installing new exhaust pipes?
A: Yes, in most cases, especially if you’re installing a full exhaust system or significantly changing the airflow. New pipes can alter the engine’s air-to-fuel ratio, which might lead to overheating, reduced performance, or even engine damage. A fuel tuner or ECU re-map is highly recommended to ensure your Harley runs optimally and safely.
Q: What’s the difference between slip-on mufflers and a full exhaust system for a Harley?
A: Slip-on mufflers replace only the rear section of your exhaust, usually the mufflers, and are generally easier to install and more budget-friendly. They primarily change the sound and offer minor performance gains. A full exhaust system replaces the entire exhaust from the engine header pipes back, offering more significant changes in sound, performance, and aesthetics. Full systems often require more complex installation and typically necessitate re-tuning.
Q: Will aftermarket exhaust pipes increase my Harley’s horsepower?
A: Yes, in many cases, aftermarket exhaust pipes can increase horsepower and torque, especially when combined with an optimized air intake and a proper tune. Performance exhaust systems are designed to improve exhaust gas flow, reducing back pressure and allowing the engine to breathe more efficiently. The exact gains depend on the specific exhaust system and how well the bike is tuned afterward.
Q: Are stainless steel or mild steel exhaust pipes better for my Harley Davidson?
A: Stainless steel exhaust pipes are generally considered superior for longevity because they offer excellent corrosion resistance and can withstand high temperatures without rusting. They often come with a polished finish that retains its look longer. Mild steel exhaust pipes are more affordable and easier to weld for custom fabrication, but they are prone to rust if not coated or maintained properly. The “better” option depends on your budget, climate, and willingness to maintain the pipes.
Q: How do I choose the right exhaust pipe diameter for my Harley?
A: The optimal exhaust pipe diameter depends on your engine size, desired sound, and performance goals. Larger diameter pipes generally allow for greater exhaust flow, which can be beneficial for high-performance engines, contributing to a louder, deeper sound. However, too large a diameter can reduce back pressure excessively, potentially leading to a loss of low-end torque. For most Harleys, common diameters like 2.5-inch or 3-inch are good starting points for aftermarket upgrades, balancing flow and torque.
There you have it, fellow riders – a comprehensive look at some of the best exhaust pipes for your Harley Davidson. I hope this guide helps you make an informed decision and find the perfect pipes to give your bike that signature roar and enhanced performance.
