I considered how this change might affect my horsepower and torque, especially if I was upgrading other parts of my exhaust system simultaneously.

Price Range

When I started comparing prices, I found a wide range depending on the material and brand. I had to set a budget that balanced quality and cost. While I wanted something affordable, I also understood that investing in a higher-quality adapter could save me money in the long run by avoiding replacements.
