Why put in a muffler? Don't waste your money. Put a pipe in to replace the current muffler and I will garauntee up to a 20 horsepower increase AND popping and crackling...:head:

another popping and crackling 6 cyl, just what the world needs!!!! :cussing: :kidding: Guess its better than a 4 banger.
There is a post around here with someone that has a 40 series flow on a 4.3 and said they hated the sound. That is a two chamber muffler, so I assume a single chamber would sound worse. Although, some people's opinion of 'bad' could be another's opinion of 'good,' so it is hard to say. Find that post and ask him to describe the sound. It might be the sound you are looking for.
