    I would like to add a set of headers with these. Would i have to get shorty or long tube headers?

    • With the Magnaflow Competition Cat-Back Exhaust w/ X-Pipe, you will only be able to use shorty headers. If you decided to go long tube headers you will not be able to use the x pipe included in this kit, or you will have to have it modified to work with the long tube headers of your choice.

      Magnaflow Comp Cat-Back 12BOSS

      Excellent fitting product. Great quality as well. I opted for this system because I wanted to retain my side exhaust. Only reason I rated as a 4 and not 5 is because the system is not as loud/mean sounding as I had hoped for. It definitively is much improved over stock but I feel like a Boss Mustang should be noticed by all. I have Borla on my 2010 GT so maybe that’s why it sounds so quiet. All in all I am very satisfied with the purchase. I would recommend if you are wanting to keep the side pipes on your Boss. I believe the side pipes is just another thing that makes the Boss Mustang so unique and great.
