Can you change single exhaust to dual exhaust?
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”. On a 2003 true dual exhaust is perfectly legal.
Is dual exhaust better than single exhaust?
However, most would agree that a dual exhaust will give you better performance gains compared to a single exhaust system. Because the exhaust gases exit each manifold through two pipes rather than just one, they can exit the engine faster and provide additional horsepower gains.
Does changing exhaust reduce mpg?
Obviously, boosting fuel economy by 2 mpg is going to help pay off a new exhaust system pretty quickly. Bottom Line: Adding an after-market performance muffler or exhaust system will improve engine efficiency from 2-10%. Improvements in efficiency can be used to either increase horsepower or improve fuel economy.
Which is better straight pipe or muffler?
Straight pipes offer better flow than many popular performance mufflers. This can be helpful if you’re trying to maximize performance and fuel mileage. However, high quality performance mufflers such as Paradox Performance Mufflers offer flow just as good -and sometimes better- than straight pipes.
Will a muffler shop straight pipe?
Anybody can just go to the muffler shop, throw the mechanic a hundred bucks and they can build you a straight pipe exhaust from left over parts. The thing is, it won’t sound very good at all and you’ll probably get a really “Raspy” sound quality when at full throttle.
Are Glasspacks louder than straight pipes?
The shorter glasspacks are much louder than the long ones for obvious reasons. I would stay away from straight pipes. It’s just my opinion but they sound like crap most of the time. If you really want loud you might look at getting rid of the catalytic converters as they absorb lots of sound.
What muffler is louder than a Flowmaster 40?
While the Super 40 is generally seen as being louder – although not as loud as some other mufflers – the Super 44 has a more aggressive bite to its noise. Really the main difference is that the Super 44 produces a deeper sound although there is some internal resonance too.
