Exhaust information help...
Newbie question...
What is a cat-back? I know what an X pipe with cats is... (or an H pipe) And then there are mufflers and exhaust tips... But where does the cat-back fit in? Is it a replacement for the mufflers? Thanks |

catback just includes replacement catylitic converters. The stock H-pipe has 6 cats on it, so do get the cat back system means you go from headers back, and replace those 6 w/ 2. If you don't have emissions and aren't a heavy tree-humper, than just go o/r h-pipe...but if you do, and you want to spend the extra couple hundred, get a catback.

You've got your Headers then its connected to your H or X pipe then at the end of your H or X is the Cat-Back or After-Cat Exhaust. It is called a cat-back because it hooks up from the catted X or H pipe then runs over your solid axle and out the back. But with the '99 and up Cobra's it runs under the IRS.
Heres a web-site http://www.magnaflow.com/03cat-mustang.htm

Sorry bout the mis-leading info earlier...
One more question, if the cat-back does not include cats, then what does a high flow cat-back mean?

Ok.... I'm still confused....
The X-pipe can have cats on it... Then you can have a cat-back which also has cats... Does that replace the mufflers??? Or is the cat-back between the X-pipe and the mufflers? Thanks for you patience... |

since you cannot get cats seperate (orig. equip.) unless after market weld on, most companies sell you an X or H pipe with or without cats. therefore, your cat back set up connects from your H or X pipe after the cats. you have like a foot or so of intermediate pipe that is flanged and connects to your pipe before the muffler as well. the cat bac includes mufflers and pipe that run all the way back... hope that clears it up for you..

A traditional cat-back is from beyond the mufflers to the tips. You can get a catted X or H that goes where the o/r pipe would, right behing the headers, but has high flow cats that should pass sniffer emmisions. Passing a CA visual is a whole different story.
