I bought the rear exit kit and have had a few issues, which is almost
to be expected when it comes from China.
My package did not contain the passenger side exhaust tip, packing list of materials, or clamps that are worth your time. Speed Engineering will, hopefully, replace the missing tip and I am buying 9 stainless band clamps to replace the junk pieces in the kit.
As mentioned earlier in the thread, you will need to grind down the washer for the rear-most hangar brackets to fit.
On the bright side, it sounded pretty good for the 50ft I drove it out the door of the shop.
