After having the Borla/Switchfire set for a thousand miles, I am rather disappointed. I will def. go back to H pipe. Not sure I heard a difference in stock and Borla set up.
Went from GT350 to GT500 in 2019, test drove M1 in 2022, back to GT500. I'm still in love with the GT350 for shifts, sound, and RPMs. I was left wanting with the M1, was like, when does the power come? Now, I have not driven a 350 since 2019, so not sure how I would feel since owning a 500...
