    5 Stars   Awesome sound, and fit
    By on 4/4/2014
    I was working on my 7 up when I noticed the stock exhaust was rotted out! Well that was the excuse I needed to purchas the flowmasters ! They came to the door in perfect shape and in record time. The installation was a breeze and in no time I was taking the car off the jacks. The sound is great! It's that traditional 5.0 sound that you expect from flowmasters! Thanks to latemodelrestoration for great products, super fast shipping, and awesome customer support!

    Yes, I would recommend this item to a friend!

    5 Stars   Sounds Awesome!!

    Image uploaded by Pastor N. It took me a while to decide which Flowmaster cat-back system to buy. Had to get Flowmaster due to the use of my MM Panhard bar system. The sound is outstanding, but the fit could be a little better. These went on my 93 Cobra. The fitting issue was between frame rails and also differential housing. I used extended exhaust tail - pipe hangers due to factory Cobra rear bumper. I will have to go to exhaust shop to modify to my liking. Other than that, it's aftermarket and at times they just don't fit well.

    Yes, I would recommend this item to a friend!

    4 Stars   Very easy install
    By on 4/21/2015
    Just installed the new cat back system on Sunday. Very easy to install and worked perfectly with my BBK H-pipe. The sound is MUCH loader than the old stock mufflers with the same H-pipe. I like the sound, especially under heavy acceleration. The only complaint is a significant drone at 2200 rpm - no issues above or below that RPM. This is a high quality system. I was the exhaust buyer for Ford Purchasing back in the 80's and 90's and I know a good system when I see it. And yes, I bought all of the original Mustang factory systems!

    Yes, I would recommend this item to a friend!

    5 Stars   Extremely happy with fit, and classic Flowmaster sound.
    By on 5/2/2016
    Image uploaded by William W. I was quite amazed how well these fit with some minor adjustments. 84 Mustang only came with a single exhaust, but I ordered all the correct hangers and hardware. Holes were already in the correct locations so no drilling to get the hardware to fit. The previous dual exhaust was hacked in and never fit or hung correctly. These are nearly perfect, even running the torque arm and panhard bar from MM, there are no clearance issues.

    Yes, I would recommend this item to a friend!

    5 Stars   Quality product, great fit.
    By on 6/18/2015
    Well made catback system. Sound in the car is loud, but not too loud. I was unable to install the tailpipes in my garage because I could not safely jack the car up high enough. I took them to a local shop and paid $40.00 to have them put on. No problems with the install other than that.

    Yes, I would recommend this item to a friend!
