Xpipe vs Hpipe with longtubes?
 

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)?

Go on Bassani's Website and check it out. In my opinion X-pipe's sound awesome even with converters. I love mine!

I don't know how to make this a link but there is the address. The part # is 5093R-3 and it lists for $489.99. I am positive you will like it. It gives the exhaust a distinctive raspiness that gives me the chills every time I drive mine. Hope this helps.
I doubt you would notice any power loss. It will be a little quieter but I think it will sound better. Just my .02

I didn't realize that you could just copy the address and paste! Click on the link and have fun!

Thanks for the links guy... just curious anyone out there in San Antonio or Austin(i'm in san marcos) that knows somewhere I could get inspected with no cats. http://www.mustangworks.com/msgboard/smile.gif
