Z06 Maximizer Performance Headers with x-pipe
Application fits Corvette 2005-2013 ZO6 LS7. I have total of Qty 3 new old stock, dated 2014 for sale.
$550 cash, for one ( 1 ) complete set. One box opened for these actual pictures. Complete new old stock #MH11425B Maximizer H P Headers, Resonators, X-pipe clamps and gaskets.
Specs: 304 stainless steel, 1 7/8" primaries (round port), 3" secondaries and 3" collectors. The headers have nice looking sandblasted finish.
These also fit LS3. I have one set of these going on my 2008 Automatic Transmission Corvette with LS3 engine and the large 3" ZO6 X-Pipe needs adapted down to smaller LS3 exhaust and mufflers.
Last picture is retail picture on my invoice. These headers are new old stock from sealed box, never installed.
Pick your's up across from Collinsville,IL City Hall parking lot at 125 S Center St, Collinsville,IL 62234. This is safe, well lit and covered public parking area 1 block from Main Street. I can meet you there. Message here or e mail direct for date and pick up time.
If you need these shipped, contact me for my address that you will need to send payment check or money order to. 1 week for payment to clear, if in rush do not buy. Buyer will need a Fed Ex or UPS account in your name so I will drop your PAID FOR parts at Pac Mail and they will bill your shipper. Buyer must pay shipper. I will not be able to give buyer a shipping quote.
This box may be over 70 pounds, buyer pays ALL shipping and extra handling costs such as double-boxing through Buyer's shipper Pac Mail, 407 Beltline Rd, Collinsville,IL 62234.
