Best Exhaust For Diesel Trucks – We’ve been analyzing and covering the diesel performance industry for two decades now, and in that time we’ve watched various trends come and go. But we have to admit, we’ve seen some real doozies infiltrate the ranks of the compression ignition crowd over the years. From dumb mods like smoke switches to “hey, look at me” mods like giant exhaust tips, many diesel upgrades (or should we call them downgrades?) are done in bad taste. Other mods, like stacked fuel boxes and aggressively stretched tire fitments, are done with added performance or improved curb appeal in mind, but come with safety risks.

Whether they’re a surprising addition, bad for performance, detrimental to longevity or just flat-out dumb, the following foul-ups are about as bad as it gets in the diesel truck game.

This is at the top of the list for a reason: it’s stupid. If there was a reason for the diesel industry earning a black eye, installing a smoke switch would be it. In late-model diesels, manipulating the solenoid for the variable geometry turbocharger (VGT), coupled with fueling mods, can give excessive smoke out the tail. It accomplishes this by disabling vane (or nozzle) movement on the exhaust side of the turbo, which eliminates the VGT’s ability to build boost quickly when the engine is lagging at low rpm.

Choosing The Correct Diesel Exhaust

Exhaust stocks are on the decline in the diesel aftermarket, but we won’t be happy until all the bull howlers and special homemade systems are out of sight. Not only are they hideous in most circumstances, but they call for you to cut irreparable holes in your truck’s bed. Of course, you can get around cutting holes in the box floor by keeping the piping external, but let’s face it, this is equally terrible, if not even worse.

Fortunately this doesn’t happen with nearly the frequency it used to, but nevertheless, someone out there at the moment is probably about to stack an old timing box over another ancient product that does the same thing. Trust us, just because you score two stackable devices for next to nothing doesn’t mean your engine wants anything to do with them. Deadly combos where both boxes advance timing can wreck an engine, not to mention cause some pretty awful injector rattle and scary rail pressure. With how far custom tuning software has come for diesels in the last 10-15 years, it’s best to stick with platforms like EFI Live and keep your engine safe!

Attention to the diesel exhaust system has always been a “thing” in the diesel performance segment (perhaps due to the coolness associated with it in the Class 8 world), but some examples are simply over the top. Unfortunately, while comedy in some circles, the implication with the most oversized exhaust tips is the truck’s ability to trap a lot of unburnt fuel. When this fad will completely disappear from existence, we will gladly bring the shovel and bury it ourselves. Just look at the size of the top in relation to the truck’s rear differential…

We’re not saying your local slushbox wizard isn’t capable of building a diesel-specific automatic transmission and the major players in the diesel game, but many can’t. While the corner tranny shop may know how to build one heck of an automatic transmission for a gas vehicle, they may not take care to accommodate the abundance of torque that a diesel-rated one will be exposed to. In both transmission and engine failure, the torque produced by a diesel causes the most damage, not the horsepower. After you have to pull out a locally built transmission more than once, you will quickly realize your mistake.

Arguably no other mod can change the way a diesel drives more than a turbo. Unfortunately, the bigger is better theory that runs rampant in this particular niche can make a truck a chore to drive. Neglecting or failing to seek advice on your turbo upgrade can lead to a laggy, lazy driving experience or even a turbo that sits on the surge line of its map while cruising at low rpm. Trust us, there are scores of diesel owners who bought into the hype, purchased a bigger turbo, got tired of the lag and eventually went back to stock. Our advice: do your research and seek professional guidance on the right turbo for your specific needs. Failure to get this right can make you hate driving your truck.

They can hold some serious torque, but some of the multi-disc clutches in the diesel aftermarket are extremely noisy. With the float plate (or intermediate flywheel) located between the clutch discs being the reason but also an inevitable component in a dual-disc system, many enthusiasts accept the shaker as part of the power-adding process. Still, many others come to object to the noise, which is especially pronounced at idle when the clutch is disengaged. Throw in the stiff clutch pedal that comes with an aggressive, dual-disc clutch designed to handle 1,500-plus lb-ft of torque, and some diesel owners eventually find themselves parking the truck that was once their pride and joy. . Full disclosure: We’re not saying you shouldn’t upgrade your clutch, but stick to a single disc if you can. If a dual disk is the only solution, you’ve been warned.

Every automotive enthusiast wants the vehicle they have poured their passion into to stand out. One of the most common ways to do this these days is through huge, high-dollar wheels with tires stretched to fit them. Diesel owners do this to make their wheel “pop” or stick out and attract attention.

Unfortunately, aggressive stretch fitments are dangerous because the strength of the sidewall is removed. Ultimately, this can lead to a damaged sidewall or the tire de-beading the wheel. Aggressive tire-stretching is a bad idea. Even the trucks you find in the show and shine area at any diesel event are typically still used to haul with or receive daily.

The end of affordable V8? Why the discontinued Chevy Camaro is a bigger deal than you think When it comes to 4×4 vehicles, we here at Sandgate Auto Electrics have seen it all. We have many clients who are curious about ways to upgrade and modify their vehicles to get the most out of them on the road, while avoiding any potential problems.

Standard 4×4 exhaust systems are often very restrictive to your vehicle’s performance. This is why we get so many questions about upgrading; There is much to be gained by installing a high-quality performance exhaust system. While increasing power, you will also experience greater fuel economy.

The main things people look for from their diesel exhaust systems are efficiency, increased torque and pulling power. You can delve much deeper into potential upgrades, so we decided to put together this piece based on the five things you should know about 4×4 diesel exhaust systems.

As we all know, our 4×4 vehicles can be put through the wringer, so we need to do our best to take care of their components to ensure they survive whatever hell we want to drag them through! One of the best things you can do for your engine is to make sure there are no airflow issues. Old air can cause problems, especially if your 4×4 is a diesel.

Old air leads to a build-up of burnt fuel residue and oils, and this can lead to engine problems while chewing your fuel. To make sure that this is not a problem, you need a snorkel. The snorkel helps clean air flow into the engine and out of the car. A high-quality snorkel pulls clean air from the roof into the engine. To really ensure that this process does the trick, an aftermarket large diameter exhaust will help get the air back.

All this means that the engine does not have to work as hard, which leads to better fuel economy and longer engine life.

It’s a strange misconception that the louder your aftermarket exhaust is, the better it performs. This is not the case however, loud exhausts are just for show and in some cases can actually be bad for your vehicle. Good quality exhaust systems don’t necessarily make things louder, rather they change the tone of the sound your exhaust makes.

The reason for this is the larger diameter of the exhaust system creating a deeper sound. When you pair one of those big exhausts with a high flow muffler and catalytic converters, you’ll be looking at a setup that provides optimal performance and better fuel economy, and when you’re taking long trips across the country, it’ll be much more. Benefit as something that sounds like an animal.
