Baffle Insert Descriptions
Khrome Werks 202708P Performance Insert – This insert does the best at recovering torque curves without a loss in high end HP. It does tend to quiet the exhaust down a bit but for the most part, these will be used in higher performance applications such as 124 and 128 big bore bikes that would be ultra loud to begin with.
Khrome Werks 202711P Ripper Insert – This is a piece of 2.25” straight pipe with a flange on it so you can bolt it in. It basically turns the muffler into a straight pipe. These things make even a slip on behind a cat ROWDY.
Khrome Werks 202712P Louvered Insert – This insert raises low end torque while not sacrificing sound level. It does drop the high end horsepower level a bit and changes the tone o the muffler a bit making it sound more like a deep Rinehart or RC muffler.
Khrome Werks 202713P Decibel Reducer – This insert is strictly to reduce the decibel output of our mufflers to CA sound level. They will reduce it according to SAE J2825 sound test which is what CA uses for their acceptable sound level.
