if i unbolt the Y wont it throw a check engine light code?

 

that vid is so old LOL

 

Yes, because your O2's won't be reading anything.

Just do like Sr said and pull the Borla.

 

That vid is from back before this board was created. It was longtubes, no cats, y-pipe, and loudmouth from what i remember. DEFINITELY a no cat/y-pipe set-up. I'm not sure how anyone could think that sounded good with all the rasp but that's just my opinion. They guy sold that car for a supra because he thought supras were so much better than his car. He was a member of ls1.com and I'm pretty sure a member of this board too and i think his name had something to do with transformers(if you look closely he has the transformers/optimus prime face logo instead of the bird between the taillights. I have a video of his car at idle with a cam but it's on my other computer and i couldn't upload it til monday if anyone is interested.
