I guess I don't understand the question. I have the strobe boxes, (3) total, hooked up to the (3) LED lights; the stock 3rd brake light and (2) LED reflector replacements. My stock brake lights are still stock bulbs and do not flash.
As for the details, I went to a local garage that does custom exhausts. He gets all of his parts from Summit Racing, since it’s pretty close to us, and we looked over the site for options. After all was said and done, I ordered a MagnaFlow Performance Muffler 12265, and a pair of new exhaust tips and he installed them. It is all 2.5" stainless steel components and pipe and cost me $450.
