Haven't done it myself (I have the 3/4 or "non" 3/4 system and bolts into the HTEV system) but do a search as there is tons of info. If I remember right there are (2) cables coming from the servo (connecting to the HTEV) which you remove along with the HTEV. Not sure of your mechanical ability, you may want to grab a buddy as I've read a full system install isn't a piece of cake (new header, HTEV removal, etc.). Again, do a search, there should be lots of info here. Good luck.jerseydrew said:how exactly do you disconect the htev? do you just unplug the wires and tuck them somewhere or do you disconect them from up above (somewhere else)? i am going to order a new exhaust and want to instal it myself.
