      nice looking but leaky flange

      I installed this on my 89 LX 5.0 with the stock headers. Easy enough to put in but I could not get the passenger side to seal up. Took it apart several times but it appears the H pipe flange might be too large for the stock header flange. The leak was bad enough to be heard while driving. Disappointed. Will most likely have to get after market headers to see if they fit better. Project on hold for now.

      Get what you pay for.

      Not a simple bolt on and off. I had yo oval the holes to the manifolds/ factory headers. After bolting it on it wouldn't line up with the mufflers. This car is completely stock . I own a 97 mustang cobra , I installed a BBK H pipe without a problem. Sorry but I did not like this pipe.

      Great fit, excellent quality and fast shipping!

      The Mac off road H pipe was a direct bolt on, easy fit once factory H pipe is removed, the key to this system fitting so well is it’s 3 piece design. Note to all that are installing make sure to assemble all pieces before tightening any clamps, the right side O2 sensor will be close but if you rotate the H pipe leg counter clock wise before tightening it works perfect! Noticed quicker throttle response and paired with the Flowmaster American Thunder cat back exhaust it sounds AMAZING! Gave my 93 LX Hatchback the true Foxbody sound I was looking for!

      Very good fitment

      Work very well with equal length shorty headers and dumps. Bolted directly on place without any modification; bends were perfect. My car is no longer fuel injected, but it was very simple to plug all of the sensor ports using steel NPT threaded plugs welded in place and stock mild steel bar for tube connection. Be sure to use a corrosion resistant heat specific paint on any welds to help avoid corrosion issues.

      Great for the price!

      Can't beat the value. Fit pretty good and sealed well. I bought it because my old H pipe (2 piece MAC) would not seal up to my new BBK headers. One of the down tube ends came dented but i tapped it out with a ball peen and it was fine. A little raspier than my old H.

      Sounds great!

      Take your time when installing. This was my first go with putting exhaust on myself. Install it loose front to back and check for gaps as you go. Otherwise it will be more difficult than it has to be. I had to go back and redo mine because i was in a hurry. It sounds great now, definitely woke the car up!

      Had to cut one of the rear hangers and reweld it at a different angle to get the pipe to fit properly. You get what you pay for, but all said and done its not too bad.
