Decat Pipe, Stainless Steel - BSA Gold Star 650

BSA GOLDSTAR, DECAT PIPE, STAINLESS STEEL, BRUSHED FINISH 

Manufactured in the UK from T304 stainless steel, this decat pipe is manufactured to an excellent standard using high quality materials. 

The original collector box is of a considerable size and weight and adds a large restriction within the exhaust system. This decat pipe bypasses the whole collector box and allows the bulky and heavy section to be completely removed from the bike, offering over an 80% weight saving. This gives an improvement in both performance and noise output, giving a deeper, healthier exhaust sound. 

They come with the provision for the oxygen sensor and utilise the standard mounting points and fixings. The end fitting is swaged to the correct size as standard, to remain compatible with aftermarket silencers.
As with all stainless steel exhausts, as they go through heat cycles there will be a change in colour, particularly around the header area. 

Suitable for the new 2022-2024 650 BSA GOLDSTAR.

Note: In Europe, the Euro5+ models were introduced for the 2025 model year and feature two lambda sensors in the exhaust—one pre-cat and one post-cat (easily identifiable by inspecting the exhaust). For these Euro5+ models, this decat pipe is not suitable.
