I have straight dual 3 inch exhaust on my truck with 2 chamber Flowmasters with dumps. It is pretty loud inside and out. I am getting new exhaust done with an X-pipe and was wondering what kind of mufflers I could use to quiet this thing up some. I was thinking of 3 chamber Flowmasters but was wondering what the people on here thought. It is driven regulary on the street but not a daily driver.
