Review on π Dynomax Ultra Flo 17552 Performance Exhaust Muffler by Jeff Robeson
Sounds good. Deep idle noise
Sounds good. Low pitched noise when idling. soft sound when accelerating and soft at full load. Installed on Sierra 5.3. It's not like the Flowmaster on a truck, the Xpipe gives it an aggressive sound, more like a Camaro or Corvette.
Pros
- Test for one year
Cons
- So far so good
