What People Say

Synthesized from 40 reviews · 100% verified purchases.

Choose mufflers matching your engine size and volume preference; Thrush and MagnaFlow offer deep drone-free tones for most engines, while Cherry Bombs are very loud and may degrade to a straight pipe over time. For heat wraps, proper surface preparation and extra adhesive prevent peeling.

Praised for
  • Affordable price and great value
  • Easy installation
  • Deep, aggressive sound without excessive drone
  • Effective heat reflection and protection
Common complaints
  • Sound may be weak or raspy on certain engines
  • Minor manufacturing and quality inconsistencies
  • Adhesive weakness or peeling on heat tape
