A local dealer had a 2025 Rebel G/T on their lot I have not heard how is sounds and was curious what's different with the G/T's "Passive Cold End Exhaust". The G/T is still a SO engine but uses the HO left and right front exhaust pipes and left and right exhaust extension pipes that connect to a dual in dual out muffler. The muffler is not the same as the HO version and the resonators have different stampings on them too. The G/T muffler is stamped C-9476 left resonator is C-9458-L and right resonator stamped C-9458-R. You would think running dual pipes into the muffler and not having a 2 pipe into 1 Y pipe up front would increase power but nothing is mentioned that I've read.
For comparison my 2025 Rebel has a single in dual out muffler stamped C-9428 left resonator C-9411-L the right is C-9428-R.
