			 I have mac 1 5/8 longtubes with the matching offroad hpipe on my car right now.  It won't pass inspection so I am thinking about buying an xpipe with cats to replace the hpipe.  Does  anyone make a xpipe to fit my headers?   How much hp will I gain/lose by going from an offroad hpipe to a xpipe with cats?   Also how much quieter will it get(I WANT IT LOUD but I need that inspection sticker)?
