Quick delivery of well packaged product. Instructions about preparing to install the headers were great. Complete project took about 6 hours and I was not hurried. These shorty Headers gave my 2010 6L GMC 2500 exactly what I was looking for... about 10% better fuel economy and 5% more mid-range power while towing my RV.
