After my experience with the Kooks side exhaust and hearing everyone else talking about their own fitment issues I have been thinking of having some made. After making mine fit I know exactly what they need done to make them right. Actually much better than anything out there right now. I have a good friend that is a fabricator. Went to NASCAR fab school and now owns his own shop. Almost exclusively fords and a huge mustang fan. Anyway to get to the point. He looked at my 2012 boss and after telling him my issues decided he can make these better. Way better than Kooks. Sorry Kooks. Using the same grade stainless steel and putting the bends in the correct place using my car as a template. Also putting a short piece of flex pipe like ford did at the factory to avoid rattles. We can make them better and cheaper than anyone else. The only thing is I need to make about 20 sets to make it worthwhile to all of us and keep the price down. We are thinking around 350 a set but not sure until we get into it. Oh and they will be garuanteed to fit your factory h pipe. These things sound like a race car. I won't lie they are loud but that's what I want. You can quit them down with the plate or the qfre still if you wanted. I'm posting it here exclusively for now to see if I get enough interest to go ahead with this. Please respond if your interested or have questions. Like I said I need about 20 or it's not worth the effort. As far as I know the 2012 and 2013 boss are exactly the same as far as the side exhaust. Tell me if I'm wrong about that. Thanks for responding.
