What are your thoughts on Dynomax Ultra-flos?
I want to get rid of my dronemaster 44. I want to true dual it after the cats, on a 2009 chevy silverado 5.3L... would i need an h-pipe or x-pipe to make it sound better? I want to put long tubes and get rid of the cats in the future as well, but just a new muffler for now.
I have been looking into Part Number 17231.
any other suggestions? or videos of ppl with the same truck and muffler?
