Takes the 'sharpness' out

I have this on a hopped up twin cylinder Briggs engine with a long tube 2:1 header.

It does what its supposed to do and is holding up well to almost a year of abuse. Quiet, no, but it knocks the 'edge' off.

Pros
  • Fit the space I needed in the motorhome
Cons
  • The product lacks efficiency and does not provide adequate noise reduction
