Hello guys I currently have a custom 2.5 inch all the way through with a magnaflow 11386 x pipe muffler in the midsection replacing the OEM mufflers. So I plan on putting on my Tanabe Medalion but I read mufflers cause back pressure in the exhaust and am worried if the 3 mufflers would be inconvenient and perhaps get rid of the muffled x pipe and getting resonators. Thanks for your help

 

You'll be fine. Tons of guys have run the resonated X pipe and mufflers; as can be seen in the exhaust section of the forums.

 

Zero back pressure is the goal but that's unobtainable. Real-world concerns such as sound volume and character forces one to make compromises that prevent the achievement of said goal.
