Is a 2. 25 Stainless Steel Exhaust Pipe the Best Choice for My Vehicle?

From what I've read, the diameter of the exhaust pipe can impact the exhaust flow and backpressure, which in turn affects the engine's performance. A larger diameter pipe might improve flow but could potentially sacrifice some low-end torque. It really depends on your car's engine and how it's tuned.
