Headers (long) sound great and make a difference in performance with the downpipe and Y-pipe. Fits all 5.7 engines with a Fox muffler (original steel) electronic 3-inch with its unit and everything. I have two Y-pipes, one for Lexus GX and one for Sequoia, upon request. The headers and muffler fit both. The sound is amazing, pleasant, and quiet. Videos of the sound are available. The sale is very flexible and the parts are free of issues. Reason for selling: I sold the car (all parts were installed on a Lexus GX 5.7). Prefer communication via WhatsApp or Haraj. (Price 1500﷼) for all items. The intake and muffler have been sold.
