hey fellas! a while back i bought a flowmaster muffler(50 series) I loved it at first but now am realizing that there's way 2 much backpressure<img src=icon_smile_evil.gif border=0 align=middle>. If i bought the high performance mid pipe from speedstate this would increase my performance noticably wouldn't it? and also does anyone know the difference between speedstate's midpipe and hdk's? I really hate 2 buy from hdk but it's bout 100 bucks cheaper. thanx<img src=icon_smile_cool.gif border=0 align=middle>
