Do I need clamps or brackets to install this?

You'll need exhaust clamps sized for 3.0" to 3.15" tubing to secure it to adjacent pipes or mounting points. The flared outlet accepts standard U-bolt clamps — verify your clamp diameter before ordering.

Can I weld this directly to my existing exhaust?

Yes, stainless steel can be TIG welded. Make sure your welder has stainless experience — MIG or stick welding isn't ideal for this material. Prep the joint surfaces clean before welding.

Does this come polished or raw?

This is raw stainless tubing. If you want a polished finish, you'll need to finish it yourself or have a shop do it post-installation. Raw stainless will develop a light patina over time but won't rust.
