BEST BANG FOR YOUR BUCk IMO
INSTALL was EASY! Grab a couple of jackstands and start wrenching! Just make sure to uninstall your front pipe and over pipe for more wiggle room. There's a bolt that is hard to tighten on the driver side ports once the Borla UEL's are on, but a swivel joint socket or swivel spanner will take care of that.
SOUND- Paired to a cat back it will be amazing, my personal set up, is as follows. Borla UEL, stock over pipe, 2.5inch catless front pipe, stock midpipe welded to a custom 2.5 inch dual tip Y-pipe. The sound is perfect and full of subie rumble!!
NOTE- Always be sure to check quality of parts ordered before continued work. Personally the headers were great, but I have read horror stories online and as a review above mentions.
