Keeping fresh packing inside is critical for maintaining peak power and keeping exhaust noise levels within legal limits.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this fit my stock exhaust pipe?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes, the Pro Circuit R-304 is designed to be a direct bolt-on for the factory exhaust pipe, offering a simple way to improve your bike's power delivery.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e Don't wait until the bike sounds \"hollow\" or metallic to repack it. As the packing breaks down, it creates backpressure that can actually hurt your engine's performance and throttle response. Replacing the packing regularly ensures your bike pulls hard out of corners every time you hit the track.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/new-ktm-85-sx-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eKTM 85 SX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/husqvarna-tc-85-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eHusqvarna TC 85 Performance Parts\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/gas-gas-mc-85-performance-parts-and-accessories-moto-house-mx\"\u003eGas Gas MC 85 Performance Parts\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
