Been a way long time since I got back to the track car..but now I have an exhaust system to put on the car...mating to my headers..should both flow better and be much more quiet than the previous setup..

Hope to get it on the car and start back on the interior cleaning so I can actually drive it again LOL..

close...but no cigar.. you need one more muffler to make 92db... i have your set up and a rear mounted fart can, AND a turn down and barely make 92db. the set up how you have it now is more like 96db.
