Answer: Removing the Y pipe and converting your truck's current "single" exhaust system into a "dual" system will cause a smog check failure. The smog technician will consider the modification you've made as a "tamper". You must keep the original exhaust system configuration designed by your vehicle's manufacturer.

Can a car have a single exhaust and a dual exhaust?
However, some vehicles may have dual exhaust tips while the overall system is still single, or may split at the muffler, which results in a dual exit on what is technically still a single exhaust system. In a true dual exhaust system, each exhaust manifold is attached to its own, independent exhaust system.
How do 2 into 1 exhausts work?
When the first cylinder sends a pulse of exhaust shooting down the pipe, it helps to pull oxygen into the second cylinder. Then, the second cylinder helps the first in the same way, and the cycle goes on. 2 into 1 exhausts can offer a better balanced airflow in your engine which can result in more torque and a smoother idle.
What type of sound does a dual exhaust make?
Depending on whether you opt for an H-pipe or an X-pipe, the design will largely determine what type of sound a dual exhaust will make. An H-pipe dual exhaust will emit that smooth, classic old-school muscle sound while the X-pipe will produce a louder, raspier tone.
What are the benefits of a dual exhaust system?
This is the main benefit of a dual exhaust system because the more exhaust you can push out, the more air your engine can take in, increasing your vehicle’s horsepower. Other benefits of a dual exhaust system are:
Is single or dual exhaust better?
Dual exhaust will sound more characteristic and louder than single exhaust. It works better discharging gas from the engine with less backpressure, creating better rumbling sound in the process.Jul 21, 2021
Can you put dual exhaust on a 4 cylinder?
You cannot have true duals on our 4 cylinder. It simply can't be done. There is only one manifold. it would be a waste to do anything more than a single in/dual out muffler.Dec 31, 2004
How much HP does dual exhaust add?
Most manufacturers of aftermarket dual exhaust systems claim an increase of 15 to 20 percent in horsepower (hp). A car producing 190 hp, for example, could potentially see an increase to over 225 hp, an impressive gain. Adding headers generally adds another 20 to 20 hp.
Does a 2 into 1 exhaust make more power?
Then, the second cylinder helps the first in the same way, and the cycle goes on. 2 into 1 exhausts can offer a better balanced airflow in your engine which can result in more torque and a smoother idle.Sep 19, 2018
Does dual exhaust need two catalytic converters?
Most cars will have one catalytic converter. If you have a car with a dual exhaust system, however, your car will have two catalytic converters. If your catalytic converter needs to be replaced, you may notice one or more of these warning signs: Your check engine light is on.
Do straight pipes give more horsepower?
The primary advantage of equipping a straight pipe exhaust to a performance engine is that you'll see a definite boost in your horsepower. This result occurs because the system reduces the amount of backpressure from the engine, allowing the exhaust gases to form with greater freedom.Oct 18, 2019
Do Flowmaster mufflers add horsepower?
Less restrictive performance mufflers, such as Flowmaster 10-Series , along with the removal of resonators can yield an increase of up to 15-horsepower at the wheels. Removal of all mufflers and resonators will provide slightly greater increases but remember as the restrictions are removed the exhaust grows louder.Jan 5, 2014
Does Catback increase HP?
An Increased Horsepower The cat-back exhaust system provides a vital boost to ensure the vehicle produces maximum horsepower and torque. The cat-back system has a larger diameter than a standard muffler; the wide opening creates more space for the free flow of air.
Is MagnaFlow better than flowmaster?
In short, relative to a straight pipe and no muffler, the Magnaflow-style mufflers (the ones you could see through from end to end) fared the best, the turbo mufflers fared the worst, and the chambered Flowmaster-style mufflers did only slightly better than turbo mufflers.Dec 29, 2021
What is a true dual exhaust?
A true dual exhaust system provides each head and exhaust manifold with its own separate exit allowing double the amount of exhaust to be forced out of the engine. As a result, you will likely notice an increase in horsepower.Jun 12, 2017
Why do Honda dirt bikes have dual exhaust?
Dual-exhaust ports on four-stroke dirt bikes is not new tech and was used to get larger displacement thumpers to rev farther and more free.Jul 30, 2017
Why do bikes have dual exhaust?
The double-barrel exhaust houses twin catalytic converters that help the motorcycle meet emission norms and hence had to be designed that way. The exhaust's design might be a hit or a miss but the throaty, deep exhaust note that comes out of it is music to your ears.Oct 28, 2021
