Do I need to prep the exhaust before wrapping?

Clean any loose debris or oil buildup so the wrap sits flush. No sanding or primer required — wrap adheres directly to the pipe.

How tight should I pull the wrap when securing with zip ties?

Snug it down so there's no movement, but don't over-crank — you want the weave compressed but not crimped. Test by hand before tightening fully.

Will 50 feet be enough for my headers and downpipe?

Depends on pipe length and overlap. Most single-turbo setups use 30–40 feet. Measure your run first, add 10 percent for overlap, then order accordingly.
