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