What to know before buying

Listing details to confirm

Listing details are inconsistent or unconfirmed: the title and feature text describe aluminized steel, while the technical details say Alloy Steel. The feature text also gives a 7-inch body length and package weight of 11.4 lbs, while listed item dimensions are 13 x 9 x 4 inches and item weight is 5.08 kg. Confirm the material and dimensions that apply to the selected listing. Universal fit does not establish vehicle-specific compatibility, and included clamps or other mounting hardware are not confirmed.

Frequently asked questions

How many mufflers are listed?

The listing specifies two mufflers.

What pipe size and layout does the listing specify?

It describes 2.5-inch ID inlet and outlet ports in a center/center configuration. Confirm those dimensions match your exhaust pipes.

Can these mufflers be clamped on instead of welded?

The feature text claims both welding and clamp-on installation. The listing does not confirm that clamps are included, so plan to obtain compatible hardware if needed.
