Hey guys sorry i haven't been on in a while, been busy. Just wanted to tell you guys that i received my headers from ls1 speed and put them on. They are macs. Took me and a friend 4hrs. to put them in, but let me tell you it was so worth it. I got macs with and ory pipe and the loudmouth exhaust . There's only one problem. I have this massive vibration under the car a little bit past idle ; what gives?

Sounds like something isn't tight, or the ypipe is hitting something.

Good thing about MAC's the ypipe is easy to move around till it clears.

Id guess the y-pipe is hitting something.
