Do these pipes need to be welded together?

Yes. These are individual sections — you'll need to weld them at the joints to create your complete exhaust run. This is a full custom kit, so assembly method and tools are up to you.

What sizes are included in the 16 pieces?

The kit contains a mix of 2-inch diameter sections in various lengths and angles. Exact piece-by-piece breakdown is not itemized in the product spec — reach out directly if you need the full component list before ordering.

Can I paint or ceramic coat these pipes after assembly?

Stainless polishes naturally and won't rust, so painting is optional based on your style preference. If you want a heat-resistant coating or color, prep and coat after welding — the material will accept adhesion well once cleaned.
