What to know before buying

Listing details to confirm

The listing details are contradictory or inconsistent: the title calls the tip black and chrome or polished, the exterior field says Chrome, and the feature text describes black paint. Dimensions are listed as 23 x 5 x 0.04 inches, while the model-detail text says Black 4'' Inlet 6'' Outlet. Confirm the selected finish and actual dimensions before buying. The customer feedback also reports mixed experiences with clamp tightness, rust resistance and durability, so the listing's corrosion and long-life claims should not be treated as assured.

Who is it for?

A good fit for

Buyers seeking a 4-inch-inlet, 6-inch-outlet exhaust elbow and able to confirm the intended finish and clearance.
Vehicle owners considering a clamp-on exhaust tip and comfortable checking tailpipe fit before installation.
