I'm thinking about getting the Trubendz 2.5 inch piping on my sxt. It says on the site you can use it with any muffler. Can I use it with my R/t muffler? Its the 2004 muffler with dual chrome tips. Will this change the sound at all? Thanx guys!

 

You could but what would the point be...you would be going from 2.5 inch pipe to 2.25 inch piping with the R/T muffler.
