Just a quick question.
Just a quick question. 2002 LS1, planning to do LT headers and y-pipe this month. I’m totally confused about the 02 sensors.
1- which ones will be long enough to plug back in with me new exhaust?
2- I will need to buy extensions. How many will I need? Front or rear sensors need the extensions?
3- extensions vs buying corvette 02 sensors??? Why not just extensions?. And you buy the “rear” Vette sensors and can use them as the front ones on my car?
So, I have no clue what to buy and what to do and no one gives me a straight answer. Can some one explain this to me like I’m a 4 year old. Thanx.

2002 LS1, planning to do LT headers and y-pipe this month. I’m totally confused about the 02 sensors.
1- which ones will be long enough to plug back in with me new exhaust? I have Kooks LTs and the front ones are long enough. I only used extensions for the rear sensors
2- I will need to buy extensions. How many will I need? 2 Front or rear sensors need the extensions? Rear
3- extensions vs buying corvette 02 sensors??? Why not just extensions?. And you buy the “rear” Vette sensors and can use them as the front ones on my car? I reused my stock O2s
Really my rear O2s are there physically for state inspection only, but the ecu is only reading the front ones. Regardless you will need a tune once you make the modifications. A simple mail order tune will work for this.

I don't know about Kooks headers, but the others I'm familiar with require extensions for the front O2's. It's best to get the rears tuned out because you don't need them for anything anyway.
I've used extensions but prefer the Corvette rears for the front O2's, especially if your originals are old. A fresh pair can be helpful. They are somewhat too long, but you can zip tie them up to get them out of the way. The key is to not have them too close to the primaries where they will fry and cause all sorts of problems.
