A cylindrical stainless racing muffler, but the listing is inconsistent. The title says cat-back system while the specs say muffler only, so confirm what arrives and what car it fits.

Overview
A racing buyer shopping for a stainless muffler gets the Sportsman racing design here, a cylindrical body made from stainless steel. The seller text describes it as corrosion resistant and easy to install.
Borla builds this line for racing use, and the stainless body is described as long lasting. The weak point is the listing itself, which calls the product a cat-back system in the title but a muffler in the spec table and names no vehicle.
Who it's for
A racer or fabricator who already knows the pipe sizes and mounting needs can judge the fit from the part number. Anyone expecting a bolt-on kit for a named car should ask the seller what is in the box first.
Pros and cons
- Stainless steel body
- Racing series design
- Corrosion resistant, per seller
- Title and spec table disagree
- No vehicle named
- Pipe sizes not listed
- Clamps and hangers left out
Performance notes
A cylindrical stainless body resists corrosion, and the racing design is described as built for flow and power. Fuel economy and horsepower claims in the seller text come without figures, so they should not be relied on.
