Buying Guide

Match inlet/outlet diameters

Confirm the pipe or tip inlet and outlet diameters (e.g., 2.5in inlet, 4.5in outlet, 3in OD) to ensure a proper slip-fit or clamp connection with your existing exhaust

Choose the right material

T-304 stainless steel resists corrosion and is common on longer pipes and mandrel-bent sections, while coated steel tips offer a budget option for appearance

Consider length and bend type

Select appropriate lengths (e.g., 7in tips or 40in straight pipes) and mandrel bends versus 90° elbows depending on routing and clearance needs

Bolt-on vs slip-on attachment

Bolt-on tail pipes provide simpler installation for some applications, while slip-on tips and mandrel pipes may require clamps or welding for secure fit

Check finish and corrosion resistance

Stainless finishes offer long-term durability; painted or powder-coated black tips may provide a desired look but can wear faster in harsh environments
