Is straight pipe bad for your truck?
a race car style exhaust system is a bad upgrade for a street vehicle. A straight pipe, for example, can cause exhaust gas velocity to increase. This will likely reduce engine performance below 2,000 or 2,500 RPM, making your vehicle a little slower to launch from a stoplight.

Are straight pipes legal?

Does straight pipe waste more gas?
Exhaust on an FI car can net some nice gains, ignoring the manifold, you can see up to 50 WHP on a well modded car from exhaust. A straight pipe alone won’t do much, but it shouldn’t hurt fuel economy either unless your foot gets heavier..
Is straight pipe good for Turbo?
From what I’ve heard, no. I think it actually helps the turbo because there is less backpressure against it and the less you have the better your turbo will work. There are many people with Cummins powered Dodges that are running straight-pipes and haven’t had any trouble.
How many decibels is a straight pipe?
A Harley with straight pipes (no muffler) gives off 100 decibels, the same as a car horn at three feet, according to Purdue University. By comparison, an idling car emits 35-45 decibels and in the low 70s at freeway speeds; a Harley out of the factory is 80 decibels. But remember the decibel system is logarithmic.
Is straight pipe louder than muffler delete?
Whether or not doing a muffler delete increases power is a bit besides the point on race cars. However, some straight pipe exhaust cars are just so loud that many attempts to reduce exhaust noise levels without a muffler turn out to be futile. At that point, a muffler might be installed to control the noise levels.
Do straight pipes give more horsepower?

Do turbos like back pressure?
If you are too lazy to read – Back pressure is not good for turbo (or for anything else). With back pressure, exhaust gases cannot easily flow in the exhaust system. Which means they will spool the turbo with reduced force – resulting in power loss and more turbo lag.
