The problem is that there are no cut outs on a 54, so the outlets are half obscured by the rear apron lip. There's also not much distance between the two. What are my options? cut the outlets off and weld them back on at an angle or lower downb like the original single outlet muffler?

just turn the pipe down.

either cut it and weld a bent one on, or bend the existing

Hi

The stock muffler used a short S pipe to go under the apron.
