    30543 - JEGS Dual Exhaust Kits is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Good fit and useful. I purchased this knowing that I would need to modify it a little. I was right! Head pipes were a pretty good fit to the long tube headers and needed just a little tweaking.The intermediate pipes were fine as well with no massaging those. I used Flowmaster Delta 50 mufflers which fit well. Tail pipes were a different animal. They fit over the axle pretty well and cleared the shocks, and axle vent OK. The problem was the bend was off on both sides. The angle was too much to the out side to run down along the sides of the fuel tank. I had to cut and fit with ~ 15 degree wedges and weld them in. Took a while but they look good and sound amazing. The quality of the pipe is very good and the fit to each piece is good. Hardware was just OK but worked. This exhaust was installed on a 1969 Mustang Mach 1 with a C6 and 351W. Car was made for 2 1/4" piping and the kit was a 2 1/2 system.
