Overall Assessment

Customers consistently compliment the high quality and perfect fit of our product. They particularly appreciate its usability in building exhaust systems and its excellent compatibility with various builds, including Rat Rod builds. The product's sound quality is a notable feature, eliciting a favorable, nostalgic link to the 70s era. However, there's a suggestion for an improved version that would obviate the need for an exhaust elbow in specific cars. Users widely recommend our product for its superior performance over competitors and great value for money.

How can it work if you do not remove the original muffler? If I cut the end off, that will remove the cat converter. (Which I don't care, anyway ) Will it still work any way?
