Yes - the larger engines don't breath as well with a 50 pipe
You need a 55 pipe to get the best out of these engines

Yes my rossi pipe failed on my 57 , I put the Align pipe on it , could not tune it , and it would not pull ur hat off.

Was surprised how much they do .

Thats said though , I had the OS 55 combo and tried the Align pipe on that and could not see alot of difference except for the different noise.
