What are the pros and cons of a straight-through exhaust header?
1 Answers
The advantage of a straight-through exhaust header is smooth exhaust flow and strong high-RPM horsepower. The downside is the loss of low-end torque in D gear, unpleasant odors, and environmental unfriendliness. Below are the hazards of modifying to a straight-through exhaust header: 1. Non-compliant exhaust emissions: Not only does it offer no benefits, but it also affects the vehicle's own power, as straight exhaust emissions fail to meet standards; 2. Loud noise: The modified straight exhaust pipe generally results in weaker low-RPM performance, increased noise, and excessively loud volume; 3. Higher fuel consumption: Untreated exhaust emissions exceed standards, causing severe pollution. The odor can drift into the car, and fuel consumption increases.
