MAGNAFLOW CAT-BACK EXHAUST
-
This Andy's Auto Sport how-to project is sponsored by Magnaflow and MyFordFocus.com. MagnaFlow contributed the cat-back exhaust for the project car and MyFordFocus.com helped document the install.. - Removing the stock cat-back exhaust system is not a terribly difficult job, but there are a few things to watch out for. First, if you don't have access to a mechanic's shop to get the car up on a lift, you will at least want to have four jack stands or some other way of getting the entire car off the ground and safely supported so that you can get under the car and feel safe. Secondly, be sure your replacement system came with all the proper parts, clamps and more importantly a new gasket. Finally, be patient!
- Kit Parts: 3 piece exhaust system(front pipe, center pipes and muffler, tail pipe and tip), 2 u-bolt clamps and nuts, exhaust bolts, gasket.
- Tools required: 9/16" socket, 11/16" socket(may vary depending on system), hacksaw(or other cutting tool), WD40(or other spray lubricant)
