Elite Custom Exhaust Systems in Palestine, TX
JR Discount Muffler doesn’t believe in one-size-fits-all exhaust work. If you want better sound, stronger performance, or a cleaner, more confident driving feel, a custom exhaust system is one of the most noticeable upgrades you can make. The difference is in the details: the pipe size, the routing, the muffler and resonator choice, the weld quality, the hanger placement, and how the system is tuned to your exact vehicle.
At our shop in Palestine, TX, we build exhaust systems around your goals—your performance needs, sound preferences, and budget. From aggressive street tone to quiet, “stealth” upgrades that stay comfortable on the highway, we craft exhausts that fit right, flow right, and last.
Custom Exhaust Fabrication Built Around Your Goals
A “custom exhaust” should mean more than just louder pipes. It should mean the system is designed to solve a problem or deliver a specific outcome. You tell us what matters most, and we build around it—no cookie-cutter approach, no guessing. When you come to JR Discount Muffler, we start by listening to what you want:
Deep and mellow
Crisp and sporty
Aggressive and loud
Quiet with a clean tone
Less drone on the highway

What We Can Build and Upgrade
Custom exhaust systems can be full builds from the manifolds back, or targeted upgrades that change the sound and flow without overdoing it. Common custom work includes: We’ll help you choose the right route based on how you drive (daily, towing, weekend fun), what sound you want, and how much change you actually need.
Cat-Back Exhaust Systems
A cat-back system replaces the exhaust from the catalytic converter back. It’s one of the most popular upgrades because it can improve flow and sound while keeping the system practical for daily driving. It’s also a smart choice when you want a noticeable tone improvement without getting into major changes under the hood.
Axle-Back Exhaust Systems
Axle-back work focuses on the rear section of the exhaust, usually a muffler swap and tailpipe setup. This is a great option when you want a different tone without changing the whole system. It’s often the simplest way to upgrade your sound while keeping the rest of your exhaust layout intact.
Muffler and Resonator Swaps
Mufflers and resonators do different jobs. A muffler controls volume and tone. A resonator helps smooth the sound and reduce harshness and drone. The right combination can make a vehicle sound strong and clean instead of loud and “buzzy.” If you’ve got a highway drone problem or your exhaust sounds “tinny,” this is usually the fastest way to fix it without rebuilding everything.
True Dual Exhaust Conversions
For the right vehicles, dual exhaust can improve flow and deliver a deeper, more balanced sound. We also focus on proper routing and hangers so the system sits clean and doesn’t rattle. When done correctly, true duals can also improve the overall feel of acceleration and create a more even tone across the RPM range.
X-Pipes and Y-Pipes
These components help balance exhaust pulses and shape tone. On many setups, they can smooth sound and help the vehicle feel more responsive. They’re especially helpful when you want a cleaner, less “choppy” exhaust note while still keeping a strong performance sound.
Custom Exhaust Tips and Exit Placement
Sometimes the “finish” matters just as much as the performance. We align tips evenly, keep clearances correct, and choose exit placement that looks good and avoids heat issues around bumpers and trim. Exit placement can also affect cabin noise, so we’ll recommend a setup that looks right and drives comfortably.
Materials, Pipe Size, and Fitment That Last
A custom exhaust system only performs as well as the materials and sizing behind it. If the piping is too small, you can choke off flow and limit how efficiently your engine breathes. If it’s too large, you may lose low-end response, create an unpleasant “boomy” tone, or end up with more drone than you expected. That’s why we don’t guess—we match pipe size, routing, and component selection to your vehicle and how you actually use it, so the system feels right in real-world driving, not just on paper.
At JR Discount Muffler, we recommend the best approach by looking at the full picture: your engine size and power level, whether you’re commuting, towing, or building a weekend performance setup, and the type of vehicle you drive—car, truck, or SUV. We also factor in your sound goals (and how sensitive you are to highway drone), along with your budget and how long you plan to keep the vehicle. From there, we guide you toward the right material choice and build style, focusing on clean fitment, safe clearances, strong hangers, and a layout that holds up over time—so your exhaust doesn’t just sound good on day one, it stays solid and rattle-free down the road.
Stainless Steel vs. Aluminized Steel
Stainless steel is a strong option for corrosion resistance and long service life.
Aluminized steel is often a budget-friendly choice that still holds up well in many conditions.
We’ll walk through the pros and cons so you can pick what fits your goals and what you plan to keep the vehicle long-term.
Bends, Joints, and Welding
Your exhaust system moves with heat, vibration, and road impact. That’s why we pay attention to:
Clean routing and safe clearances
Strong welds and solid connection points
Proper hanger support to prevent sagging and rattles
Service-friendly connections where appropriate, so future work isn’t a headache
This is the difference between an exhaust that sounds great for a week and an exhaust that still feels right months later.
Sound Tuning Without the Highway Drone
A lot of drivers want a stronger exhaust note but don’t want that constant “drone” in the cabin at cruising speed. Drone usually comes from a combination of pipe size, muffler design, resonator placement, and how the system resonates at common RPM ranges.
We help you avoid that outcome by tuning the system around:
Muffler type (tone and volume)
Resonator strategy (drone control and smoothness)
Pipe diameter and routing
Exit location (rear exit vs. side exit can change cabin sound)
If you’re chasing a specific sound—deep truck rumble, classic muscle tone, or a clean sporty note—tell us what you like. If you have a video reference, bring it. We’ll help match the style while still keeping your vehicle comfortable to drive.
Performance Benefits You Can Feel
A well-built exhaust system supports better breathing. That can translate into:
Improved throttle response
Smoother acceleration
Better efficiency under the right conditions
Stronger pull in the RPM range where you drive most
Not every vehicle will see “huge horsepower” from an exhaust alone, but most drivers notice a better overall feel—especially when an old system is restricted, leaking, or poorly designed.
Our Custom Exhaust Process
We keep the process clear and straightforward so you always know what’s happening, what you’re paying for, and why certain choices make more sense for your vehicle than others. A custom exhaust should never feel like a mystery project. From the first look under the car to the final sound check, our goal is to build something that fits correctly, sounds the way you want, and stays reliable long after you leave the shop.
We start with a short conversation about what you’re trying to accomplish. Do you want a deeper tone, more volume, less drone, better flow, or a combination of all three? From there we inspect the current exhaust layout from front to back, checking for leaks, broken hangers, rusted sections, clearance problems, and any restrictions that could be hurting performance. We also note things like suspension modifications, lowered or lifted ride height, aftermarket parts, and the way the exhaust is currently routed—because all of those details affect fitment, heat, and how the system will sound.
During this step, we’ll also talk budget in a practical way. Some customers want the best long-term materials possible, while others want a clean, effective upgrade at a lower price point. We’ll tell you what matters most for durability and what options give you the biggest improvement for your money.
After the inspection, we recommend a clear path forward. That might be a cat-back, axle-back, true dual conversion, muffler and resonator swap, or a repair-plus-upgrade plan that fixes existing issues while improving tone and flow. We’ll explain what each option changes—how it will affect volume, tone, drone, performance feel, longevity, and cost—so you can make a confident decision.
This is also where we help you avoid common mistakes, like choosing a setup that sounds great at idle but drones on the highway, or going too large on pipe size for how you drive. If you’re trying to match a certain “style” of sound (muscle car, clean sporty, aggressive truck rumble), we’ll guide you toward the right muffler/resonator combination instead of throwing parts at it.
Once the plan is set, we fabricate and install the system with precision. This is where a true custom build stands out. We pay close attention to the details that make the system feel “factory clean,” not slapped together:
Clearance around suspension and drivetrain: We route the exhaust so it won’t hit under load, during turns, or over bumps.
Heat protection near sensitive components: We keep safe spacing around fuel lines, wiring, and underbody areas that can be damaged by heat.
Tip alignment and overall appearance: We make sure tips sit even, centered, and visually clean—because the finish matters.
Strong hanger placement to prevent rattles: We reinforce support points and hangers so the exhaust stays stable, doesn’t sag, and doesn’t shake loose over time.
We also focus on serviceability where it makes sense. If you plan future upgrades, we can build the system in a way that makes later changes easier, not harder.
Before you leave, we do a full final inspection. We check every connection and verify the system is sealed correctly, routed safely, and supported properly. We confirm:
No leaks (so you’re not dealing with exhaust smell, noise, or performance issues)
No rattles (so it doesn’t drive you crazy at idle or on rough roads)
Proper clearance (so nothing rubs or hits during suspension travel)
Sound matches the direction you chose (tone, volume, and comfort level)
If something needs a minor adjustment to get the fit or tone exactly right, we address it before you head out. The goal is simple: you leave with an exhaust system that looks right, sounds right, and drives right—because custom work isn’t just about volume, it’s about the complete result.
What We Don’t Do: Emissions Defeat Work
We build exhaust systems the right way. That means we do not promote illegal emissions defeat modifications. If your project involves performance parts, we’ll discuss legal and compliant options and help you make a smart decision for your vehicle and how it’s used.
Vehicles We Commonly Build For
We do custom exhaust work for a wide range of vehicles, including:
Daily-driver cars and SUVs that need a clean, comfortable upgrade
Trucks that tow and need durability and drone control
Classic cars where sound and appearance matter
Modified builds that need better clearance or corrected routing
