LS1 Y-Pipe Bump Stop Hanger for 2.5″ y-pipes

It’s a well known fact that all LS1 Camaros and Firebirds cars have a “banging” issue when a set of long tube headers are installed. This banging causes the knock sensor to activate, causing a timing retard, taking away much needed horsepower under hard acceleration (usually at a drag strip when traction is ideal). This Mufflex hanger uses a rubber bumpstop that will not allow the Y-pipe to hit the underbody of the car causing this situation. The lower clamp and support rods are made out of stainless steel (tig welded for strength) and the upper rod is zinc coated steel.

    Works great!! Hardly no vibration felt on the inside of the car. Required a little bit of tweaking to fit perfect, Took 10 min to install with simple hand tools, I can now launch hard without any worying about the knock sensors pulling any timing, Definitely would recommend.
