Hello everyone, its christmas time and Rustys offroad's exhaust system for my XJ is on my list , im having some trouble deciding which of the two mufflers to choose from, the Dynomax Ultra Flow, or the Flowmaster 50 series, ive always heard the name flowmaster and relating it to a great exhaust system, but on dynomax's website, they say there ultra flow can let out over 1100 cfm as compared to the 435 cfm that flowmaster allows through....sounds like thats a major performace advantage, but i still want that signature sound...but not too obnoxiously loud....any advice on helpin me choose is greatly appreciated! :mrgreen:
