LeoVince SBK complete systems replicate the standard layout. The line and general appearance of the system is identical to OE. The header pipes are matched to the power unit, and are fabricated from AISI 304 stainless steel, which is TIG-welded, with or without filler material, according to circumstances. Where filler is used, this is always stainless steel, to eliminate the risk of corrosion.The inside of the header pipes is internally ground and profiled around all welded joints.

This process gives the production versions of the street-legal systems the same gas flow characteristics as the prototypes worked on in the development department. As a further benefit to customers, the systems used in the production department ensure that the tolerances achieved are as accurate as current technology allows, which makes them easy to fit, and provides a perfect gas seal where the pipes join.

The outside of the header pipes is treated with Scotch-Brite, which gives an elegant and workman-like performance. The whole system is characterised by attention to detail. For example, the flanges where the systems clamp up to the cylinder heads are machined from solid light alloy. The exhaust port adapter bushes are turned from stainless steel. All stainless components are treated to the Scotch-Brite process.The silencer internals are made entirely from stainless steel. Street-legal noise levels are achieved thanks to the twin chamber layout of the silencer internals, which also have a double outer skin.

Between these two skins, there is a layer of durable sound-absorbent material which withstands continuous use at 600 degrees C.

This makes a major contribution towards vehicle silencing. The silencers are oval, the same as the race versions, and are available with aluminium, carbon fibre, or titanium outer skins.
