    JEGS Cat-Back Systems are designed to produce more horsepower at an affordable price. We begin with fully aluminized 16-gauge tubing then use a proven mandrel bending process to form a smooth flowing system that is free of any "ripples" or "kinks", which restrict and slow exhaust flow. Most cat-back systems include high flow mufflers, for a throaty sound and increased flow while keeping the system emissions legal. Easy bolt-on installation.

    Rated 5 out of 5 by from 2002 Mustang got some horses Got these for my 2002 Mustang V6. Stock - a gutless wonder. Now it has some get up and go. And gave it a nice deep exhaust note. Not a V8, but still nice.

    Rated 5 out of 5 by from Great setup for a low price FAST shipping. For the price it's great for anyone who can't afford the expensive cat backs that are out there. Only one thing I wish the passenger side tail pipe clamp didn't show as much. Besides that it sounds pretty good. These are actually Heartthrob cat backs. That's ok by me.

    Rated 4 out of 5 by from Good product for the money. Installation wasn’t bad. I did it in my driveway with ramps, jack stands and a floor jack. To get the tailpipes on, I jacked the car up to separate the rear ended from the body and disconnected the bottom of the shocks. Move shock to the side and pipe clears easily. I spent an extra $4 on a clamp for drivers side muffler. Gives great dual exhaust look without being too loud for the neighborhood.

    Rated 4 out of 5 by from Great exhaust The sound of the exhaust isn't loud so if you are looking for a loud exhaust this is not for you the only time you will hear the exhaust is at full throttle which is a very deep grumble and I'm OK with that since I just wanted the dual exhaust look. over all the only difference in performance is that it is very smooth when accelerating. I had my exhaust installed professionally so I can't tell you how difficult the installation was but from what my mechanic told me it was very easy to install and he did have to add 2 exhaust hangers so it could fit right.

    Rated 4 out of 5 by from Great value Even though this system is less expensive than most, the quality was still good. A few of the rear muffler hangers could have been in a different position and I had to purchase two more 2 1/2" clamps for piece of mind to secure the mufflers better. the instructions said start at the front "Y" pipe and secure it, then work your way back. I did this and by the time I got to the over axle tubes things were slightly off. Good rule of thumb was to leave it all a little loose and slowly tighten things up. After that was done it all lined up great. The mufflers could be a little louder, so don't expect it to sound like a GT, but under heavy throttle is sounds way better than the single it had on it. I may change them out later down the road. I would purchase this again and recommend it.

    Rated 4 out of 5 by from Good fit. Bought this to replace my grandsons exhaust system on his 2002 Mustang. Every thing lined up great except the "Y" pipe of the converts. Had to use the old one that was on the car. I had ordered the system for a base model and found out his Mustang has an after market GT package on the sub frame supports. Every thing worked out good. Car is up and running and sounds great.

    What exhaust note should I expect when I buy this and will I need my own exhaust tips .

    Asked by: Stanglover92
    This will have a deep mellow tone and you will need to purchase exhaust tips if you want to add them on.

    Instead of turndowns I’d like to run the pipes straight under the rear bumper. Do you have straight chrome tip options that will work?

    Asked by: 98redv6
    This kit does not have an exhaust tip included, so you can choose any option you would like.
