Its not common and its something you should have fixed 4 months ago when it first occurred. It doesn't have anything to do with your y-pipe banging either. The actual knock sensors are located under the intake inside the valley cover that is in between both heads.

do you or have you washed the engine with a garden hose? #1 reason knock sensors take a crap is do to moisture getting to them under the intake. The good news is it's a pretty cheap and easy fix. The intake is a piece of cake to take off on these cars. Go to ls1howto.com and read the write up on swapping intakes. It'll give you the step by step on pulling and installing your intake. Your first time will probably take you between 1-2 hours start to finish. After that it's a 30-45 minute job probably.

Like above reply said it is probably the moisture from washing the engine. IF you did wash it then the front sensor is probably bad. They run about $45 a piece so it wouldn't hurt to replace both just to be safe. A word of caution when removing the intake is to watch for the MAP sensor and Oil pressure sensor because many break the oil pressure sensor and sometimes the MAP sensor while removing the intake for the first time and they can add up when doing a simple intake removal and install. Just make sure the brake booster hose does not snag on the sensor when removing the intake.

I highly doubt it's being caused by a "banging" exhaust pipe.. A sales gimick is one thing but a banging exhaust? Come on be f&cked up for real man.. In all my years of working with engines and even on boosted cars I've never once witnessed this happen. But I guess anything is possible..

I couldnt get mine to pass emissions one time cause of this code. I had to pull mine off twice. The second time was to replace the wires. And then I realized I should have worn a long sleeve jacket both times, my arms were scratched to shit. My .02
