I have a pypes axleback system and at first it was ok and i guess it still is...i just want a more agressive sound..im thinking x pipe but dont think i can go offroad cuz of mass emmissions. Will a reg x pipe make a difference in sound?
I don't know if it will get louder but it will change the tone for sure, the X makes it whine more like a high RPM euro car....kind of like a small V-8 Ferrari.
X=nascar sound and H=Muscle car sound The X with high-flow cats do a good job in making some decent power and as far as sound, like said it will sound a little different.
Here's a magnaflow Tru-X-Pipe with high flow cats? You'll get some decent gains and a more aggressive sound. http://www.youtube.com/watch?v=0CfOagAN3mo
