Because of today's manufacturing standards, a lot of auto manufacturers will leave plenty of room for improvement with most cars that roll off an assembly line. They use affordable, standardized parts to fit a large number of mass-produced automobiles. They aren't concerned about maximizing each vehicle's performance, especially when it comes to torque and horsepower.
This is why many vehicle owners opt to install aftermarket exhaust systems like Holden Commodore VE-VF. It's one of the best ways to boost horsepower, torque, and other performance factors.
Here are 3 reasons why you should consider installing a custom exhaust system:
1. It's Customized for You and Your Car
Whether you keep the stock exhaust system that came with your vehicle or you install an aftermarket kit, they will use mass-produced parts. Bolt-on kits will usually offer some performance advantages and look stylish, but they still aren't tuned in exactly to your car, truck or SUV. A truly custom-designed exhaust system will let you define the style you want and achieve the performance you desire.
2. Better Bends = Better Exhaust Flow
Most factory-made exhaust systems (and many aftermarket ones) will use what's called a "crush bend" to shape the exhaust pipes. This decreases the diameter in the bent sections of the pipe and thus slows the exhaust gases traveling through the pipes. A good custom exhaust build will use "mandrel bends" that maintain a constant diameter for the most consistent exhaust flow possible. This frees up the power in the engine for the boosts in horsepower and torque you are looking for.
3. Larger Diameter Pipes
Speaking of pipe diameter, a custom exhaust can allow you to use exhaust pipes with larger diameters than the stock ones. This can improve the flow of exhaust gases even more for increased engine performance. However, if you go too big, you might actually be hurting the vehicle's performance, which is why it makes sense to work with a professional custom exhaust builder who will help you make the right decisions.
