Astra/Zafira Z20 2 1/2" Solid Top Hat (VXR,GSI,Sri-T)

Astra/Zafira Solid top hat boost pipe, fabricated in 63mm (2 1/2") 304 Stainless Steel.

Popular for taking out a common silicone joint and giving the engine bay abit more of a "unique" look over what is already available on the market in high volume, the TigWorx Solid Top Hat made with mandrel bent pipework welded in position, gives a smooth flow to utilise the full size of the Throttle body, over the standard sized Top Hat.

Mapping is recommended with this Top Hat

* This Top Hat is SOLID, this may cause original boost pipes to be slight altered in position for a seamless fit up, however this hasn't been an issue to date due to the pipework running in a very similar position to that of a standard pipe kit *
