Going through CL locally, see an add for a fourth gen SLP loudmouth 1 for $85. This included the front y-pipe, cats, and o2 sensors- the complete exhaust. (can sell what I don't use, I guess...)
Messaged this person right away. He has just upgraded his Camaro to a long tube, out before the axle exhaust, and didn't need the exhaust, so he was selling it to get it out of the garage. IT'S MINE!
BTW he showed picts- a beautifully done Pro-street style Camaro!
Thank you CL!
