| I have a 98 Cummins Turbo Diesel. Empty it get about 26-28 mpg, towing about 20-22. My friend wants to put a Strait Pipe on it..says it will get even better mileage. Is this true? And what are some good/bad things about strait pipes? |

| What you are getting mpg is excellent mpg. Let him straight pipe the mighty cummins and you will regret it. You have your truck to pull with. I don't think you bought it to ride around in. |

Straight pipes are for young boys....who like to make a lot of noise, and have everyone look at them.
Put that pipe on your truck, and the mighty Cummins will roar like a blooming banshee. And it will probably wreck your hearing in no time.

Location: Danaburgh | Installing a straight pipe on your 1998 Cummins Turbo Diesel can have both pros and cons, and whether it improves fuel mileage can depend on several factors. Here’s a breakdown:
### Potential Benefits of a Straight Pipe:
1. **Increased Exhaust Flow**: A straight pipe can improve exhaust flow compared to a stock muffler. This can lead to better turbo spool-up and potentially more power, which could potentially improve fuel economy under certain driving conditions.
2. **Weight Savings**: Removing the muffler can reduce the overall weight of the exhaust system, which might contribute to slight improvements in fuel efficiency.
3. **Performance Gains**: Some users report a modest increase in horsepower and torque, particularly if you modify the air intake or other aspects of the engine to complement the new exhaust system.
4. **Sound**: Many enthusiasts enjoy the aggressive sound of a straight-piped diesel, which can enhance the driving experience.
### Potential Downsides of a Straight Pipe:
1. **Fuel Economy**: While some claim better mileage, others find that the lack of back pressure can lead to a decrease in fuel economy, especially during low-load driving conditions. The actual impact on mileage |

| Possibly, but not always. Removing restrictions in the exhaust system can reduce backpressure, which may improve engine efficiency slightly. However, your Cummins is already a turbocharged diesel, and the factory exhaust isn’t overly restrictive. Any gains would likely be minimal (1-2 MPG at best). |
