Yeah, it's doing me no good as a car part sitting in my room. What is the stock LS1 exhaust diameter after the Y pipe? I don't know if it's the right size- it's a 3" plate with 10 feet of cord. I went overboard on the cord because I didn't know where I was going to install it. I paid 199 minus 20 for that y pipe, so 179 and I think shipping was free... so 160? I'll go check and make sure I have all the original documentation and stuff, I know I just took it out of the box to look at it then put it back in. If I don't have the documentation for some reason then I'd drop 10 off the price.
