Magnaflow Catback Install
By Mike Friend (aka LS1 Mopar Turbo)

2003 Mustang Cobra Magna Flow Catback Install

Here is what you will need:

(1) Magna Flow Catback
(1) 14mm Deep socket
(1) 14mm socket
(1) 10mm socket
(1) Allen wrench (provided with exhaust kit)
(1) Six inch extension
(1) Ratchet
(1) 10mm wrench
(1) 14mm wrench

This should only take about 2 hours and was much easier than Ken and I thought it would be. We did it on a lift but it can also be done on your back in the garage.

Ok you will get the box of goodies. Looks like a lot of stuff but not too bad. Here are all the parts.




You get four clamps, an allen wrench which is used to adjust tip length and all the pipes. We felt that these clamps worked just fine. First thing you have to do is remove the old exhaust. It requires you to remove 4 14mm bolts. Two for each side of the exhaust.




Next you will have to remove the pipes from the hangers.  It can be tough.  Spray a little soapy water on the hangers and they'll slide right out. 





Now you can slide the exhaust right out. Once the exhaust is out, remove the hangers for the tailpipe. This will make it easier to install the new exhaust. With that out of the way, this is what you should be looking at.  If you don't see that, cut back on your beer intake.

 

Alright time to start bolting in some horsepower.  Its the same for both sides.  NOTE: The first two flanged pipes are different lengths, the short one goes on the driver's side and the long one goes on the passenger side. 

First install the flanged portion of pipe to the H-pipe. Don't tighten it all the way down because you'll need to adjust it later.



Next install the Muffler. Make sure to put the clamp on before sliding it on the pipe.  Just get the clamp snug enough so you can still move it around.  Next install the long pipe with the hangers. Make sure you put the clamp on the pipe before sliding it on the muffler. You should put the tip on now.

In the picture below you can see how the tail pipe hangs. That's why you remove the hanger and bolt it into place later after its already attached to the tail pipe hanger which is adjustable.. all you do is tighten or loosen the set screw.
 

 

When you have completed all of the steps above, it will look like this.

Now that the exhaust is in, line everything up how you want it and tighten everything down. Make sure both sides are level.

Thats it! Not too hard of a job.  I have to admit, even though I'm a GM guy it sure does sound nice and looks really good on the car.

Oops! how did that get in there!!.

If you have any questions please feel free to
email me. As always I can't be held responsible for anything you do, so be sure to check with your local SVT dealer to make sure they'll honor your warranty.
