O2 Sensor's Question....
Pacesetter Header's, Magnaflow Hi-Flow Cat's (Just wanna keep it street legal, and help reduce the sound of my exhaust), probably a custom y-pipe from a local shop, unless there's a good 1 out there to use with these cat's on these header's. SLP LoudMouth II Muffler (Unsure whether to get just 1 or 2. Dont want it to be very loud to the point, it's just unbearable), & right now. Unsure of what tip's.....
Anyway's, i know there's 4 O2 Sensor's, 2 in front & 2 in back of cat's. So i was looking over on the WS6store.com and saw the Front Bosch Corvette O2 Sensor's....So if i get these for the front 2 O2 Sensor's. Do i need to get the other 2 behind the cat's, or no??? Isnt there something about tuning the rear 2 out???
Any help with this is appreciated. Just wanna get everything figured out, and make sure i know what i will need to get or do before i begin trying to order anything.
