• Product Details

  Stage 1 Insert:

  Stage one has a smaller diameter opening that sets dB sound levels in the low to mid 90's (varies per model), yet produces industry-leading power at that dB level. NOT RECOMMENDED FOR EXTENDED USE. TUNE ACCORDINGLY.

  Stage 2 Insert:

  Stage two has a larger diameter opening that sets dB sound levels in the mid-to-high 90's (varies per model) and produces substantially more horsepower than Stage 1.
