When the new 235 gets installed in my 37 I am thinking on another type of a exhaust system instead of the duals it has now,I am thinking about running the dual pipes in a dual inlet and single outlet muffler and having a single but larger then original exhaust pipe. Anybody done this and how did it run,since it has a 235 that looks like a 216 the dual pipes gives it away its not stock so just thinking.
