With the right tools and equipment the entire exhaust system can be changed out from stock to long tubes, h/x pipe and axle back in about 4 hours. Of course I am a trained professional
Listen, I have been working on cars for a living for over 30 years. I have over $100k invested in tools and equipment. I have extensive knowledge of Ford Mustangs. I have installed a complete exhaust system in an 08 GT in just over 4 hours. Yes the car was on a lift, yes I have power/air tools, yes I know a few shortcuts to getting the job done, and yes they were American Racing long tube headers. You know if you take out the battery, and air filter assembly/inlet tube, and drop the K-member down out of the way, the long tubes go in quite easily. If you are not familiar with K-member removal, then the job can get much harder/longer. The point is that this job can be done in that time. Can the average "Joe" do it that fast? Not a chance. I did say I was a "trained professional". BTW I have also installed the Brenspeed Detroit Rockers camshafts into a 08 Bullitt Mustang in only 2.5 hrs. Another very easy job to do with the right tools and equipment.I don't mean to throw stones, but I don't see how anyone can accomplish an in car LTH install in 4 hours. I called American Racing Headers and asked them if the job takes as long as it did me or if I was just slow. They said LTH install usually takes them 6-8 hours - and I know they're professionals. Air tools and a lift will certainly help, but cutting the time in half? Just installing a grade 8 header bolt over the motor mount on the driver's side was a 1-click at a time ratchet exercise from purgatory using two swivels and a 2" extension. Then again, maybe you move like Flash Gordon...<G>
