how much will that cost u?

 

Catback tend to be anywhere from $350-600 with some exceptions. Midpipes can be anywhere from $160-500 depending on the material, cats etc.

I got my catback for $250 shipped to my door, but that was because it was on sale.

 

ok thx. Arent mach 1's stock exhuast 2.5 inch pipings? also r u getting the magnaflow X pipe and long tube headers or do u recommend getting it?

 

Stock is 2.25". I am not sure about which midpipe I am going with yet. I am either going with the SLP X pipe or a catted H pipe. I don't plan on longtubes. They cost a lot to install. I do recommend them if you want to get the most power out of your car, but I am just choosing not to do them.

 

do u know how fast a stock 2004 mach 1, thats an automatic, runs in a quarter mile?

 

2003 Ford Mustang Mach 1 (Auto) 5.6 13.88 (MT Apr '04)
