How difficult to swap Exhaust for laymen?

    Has anyone done this yet to the fist? Does it depend on what type of exhaust, connections? Can you do this with simple 12" ramps or do you have to have a lift?

    Reports I've read suggest the stock exhaust needs to be cut for removal. That could be tough on ramps.

    I cut my 2011 SES pipe on ramps, not fun. It's doable.

    Not difficult at all but yes you do need to cut the pipe.
    Although I have not replaced my exhaust on my FiST yet.
    I have done it on my '11 SES.
    Yes the header and the down pipe would be different but the Cat back is the same just a slightly different diameter.

    I would not use the ramps for this but you could.
    I just used jack stands.
    You should lift the rear of the car first.
    Then cut the pipe about 6 - 8 inches before the muffler and remove it.

    Lift the front if not already and remove the rest of the system.

    Installing the new system is just the reverse.
    Most cat back systems come in multiple pieces for ease of shipping.

    If you are going to remove the down pipe, or in my case the header, this is also down from underneath the car.
    To remove the header it was required to drop the rear of the K-Member to get the header out and new one back in.
    This should not be required with the down pipe as it is a smaller piece.

    I cut mine right where it makes the bend to go over the rear beam My car was on ramps and jack stands so it was like 6 inches off the ground. Once cut it came out really easy as the rubber holder slide off real well with just a touch of WD40 or some other spray type oil to make them slide. That downpipe bolt were snug but nothing a 12 inch breaker bar couldm't handle. Then it was just getting the old out and the new in and hung so you can fit it and get the tips where you want. Took maybe a hour.. Hardest part was putting the saw to the new pipe on the new car once the first cut was made it was easy peasy..

    FYI there are 4 rubber holders one by the downpipe connection and one before the rear beam then two back by the muffler and two 15mm? bolts/nuts at the downpipe.

    I installed the Magnaflow cat-back on my 2011 Fiesta using four ramps. I drove forward on two then jacked up the rear and slid two under the rear tires. You remove a brace under the car and cut the OE exhaust in order to remove it. It wasn't too difficult. I have not done my Fiesta ST yet...

    When I do it I want to cut where the exhaust tunnel brace is so if I have to put it back, I just get a 55mm Torca coupler and the brace will hide everything.

    20140302_123622.jpg 20140302_123542.jpg For $136.00 I got some 3 inch pipe and a dynomax super turbo muffler from summitracing. Custom cat back and it fits with the frame brace in place. Next I'll make a down pipe.

    This is a good idea.
    However unless you have a lift and disconnect the rear shocks you may have a lot of trouble getting the muffler and that much pipe out of the car.

    My thoughts if I ever go back to stock (doubt it) was to take it to a shop and have then make a slip peice to fit over the cut and double clamp it. I have never bothered to put a stock exhaust back on any car i have traded or sold yet .. just not worth the hassle of the work and selling a used exhaust while sounds good if you have a local market and have local pick up only but to ship this long pipe would be silly... and very cost ineffective..

    I can see your point but I have access to a lift and if I mistakenly buy an exhaust that is far too loud, I like a backup plan.

    I do too.
    I did cut mine in front of the muffler.
    However before I removed anything I cut a small piece of pipe to make a coupler.
    I slotted one end and welded the other end to the mid pipe.

    Prior to trading in the car, I put the OE system back with only one extra clamp.

    I did it. You can buy pre bent pipe. Just cut to length and weld.
