I am looking for opinions on various exaust manufactures. Most of all I want to know what does each one sound like. I am trying to avoid that "tinny, rattley, popping, rubbing" sound my Paceheader makes! Cost is no consequence. The second criteria I have set fourth is the "anti-rice" tip. I would like to avoid large tips if possible (I realize that sometimes I must give a little) The systems that have ranked high on my list is the Courtsey Nissan exaust, and Stromung. Has anyone actually heard these? What do they sound like? I would like to find a stainless exaust (304 perferred). Any others that I may be missing? Thanks in advance for any input!
