Complete Stainless steel long tube header set from Maximizer (which is a copy off OBX I believe) for 6.0 AWD Silverado SS (Should fit H2's & Denali's too) with cat delete resonators I bought here on eBay but did not end up using. I bought them back in January 2016 and they have been sitting in my house unboxed since then. It doesn't appear that anyone is selling the catless version here anymore so this might be your last chance to grab a catless set. I will included the stainless hardware I purchased for the header to pipe connection so all you will need is some gaskets, clamps and 02 extensions. I will include the clamps I received with them if I can find them but I would recommend getting some better made SS clamps from what I read about them.
