    Rated 5 out of 5 by from Good fit It's a good afternoon project. I did mine with my car on jackstands. A lift would make it much easier. Unhook the shocks to drop the diff for more clearance. Follow the instructions and don't tighten anything until you have it completely installed. The quality is ok. I upgraded to heavy duty clamps.

    Rated 5 out of 5 by from Excellent value I replaced a worn original single exhaust and this modified dual sounds awesome. The fit and instructions were very good. All brackets and clamps were included which some other companies’ products do not. I was fortunate to have access to a lift and believe that installing It on your back would be very difficult. Great value and price.

    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.

    How do the hangers work on this can I cut tailpipes and weld 12 inch tips to the cut tailpipe

    Asked by: Y2Ksn95
    These hangers are just a clamp that can be positioned where you want them. You can cut and weld different exhaust tips to this system.

    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.
