Butters

Ok, no less than 5 minutes ago I ordered my Borla Stinger catback. Tomorrow after I do some money moving I'm ordering my SLP X pipe. I was reading the description and it said that 2004 Mustangs need o2 extensions. I'm 99% positive that my 03 is the exact same as just about any premium 04 mustang gt. Do I need the o2 extensions? How much are they? and what are they? Thanks in advance guys.

Its just a wire harness for each 02 sensor. I needed them for my 04. The rear bungs for the 02 sensors are alot further back on an aftermarket midpipe vs. the stock one. The cost for them is about $25. www.rpmoutlet.com is where I bought mine from. I would think the 03`s are the same. You should get them just to be safe, and if by chance you don`t need them, send them back.

no you dont need em, i dont know why but they changed the location on the 04s only for some strange reason

so unless your car is an 04 you shouldnt need em

my passenger side o2 wires were short when i installed my o/r mac x pipe. all i did was cut the wire and made them longer. it was getto but it worked. took me all but 5 min.
