I have a set of the GN1 s.s. 3" muffs that I bought 2 years ago and they are no where near the same as Pitbull muffs in sound, tone, volume, performance etc...
I have a set of the 3" GN-1 mufflers .. they are similar to the original ATR Pitbulls but sound totally different which means a different design sound baffeling internally and possibly different flow characteristics.
Seeking a pair of 3" ATR Pitbull short case (11"/13" center in and out) straight thru mufflers in galvanized or stainless...must be in EC bdedrick@wideopenwest.com
