§ 02 / About this part
What it is
The PRO CIRCUIT 304 FACTORY SOUND MUFFLER/SILENCER, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
Bolt this to your expansion chamber to sharpen power delivery across the rev range. The longer canister design offers more top-end over-rev than shorter alternatives. It uses a brushed aluminium body and stainless steel inlet pipe to withstand heavy roost. Most riders swap the stock unit when the internal packing degrades or the canister takes a hit. Ensure a tight seal at the join to prevent oil leaks. Regular repacking is essential to maintain backpressure and performance. This fitment suits tracks where a broad powerband is more useful than raw bottom-end snap.
