  • Stainless steel
  • Mandrel bent
  • Optional Resonator
  • Polished 3 Chamber muffler
  • 1/2" Hangers in all OEM locations
  • Includes all required clamps and gasket
  • Direct bolt in when used with a stock exit downpipe
    During the testing phase we setup an RTA to measure db levels at various frequencies and rpm ranges . Time consuming to say the least but in the end we came up with a solution which we now manufacture in stainless. This is an amazing sounding exhaust while still maintaining a quiet tone when it is ordered with the resonator. It will be louder if you do not chose the resonator and run an offroad downpipe. Running this 2.5" catback with a catted downpipe, and resonator option can be quieter than stock and flow restriction free until around 260whp which is the average power for a Stage 3 kit with dual pass endplate, header/downpipe, & CAI. If your goal is to make more than 260whp you will want to upgrade to the 3" catback instead, but that will require cams/valve springs and more to exceed 270whp.

    Fits the 2005-07 2.0, 2005+ 2.2 & 2.4 liter Cobalts.

     

    *This product can be configured in a way that is only offroad legal.

      Looks and sounds fantastic

      Great experience. I purchased this because my lady said the car was too loud. Much quieter now but still has a good sound to it. Would highly reccomend this exhaust to anyone looking for a good highway sound but still gives you the giggles when you put your foot on the floor.

      Exhaust

      Good fit. Easy installation. A little bit louder than I would like but I am old and it is after all, a performance exhaust.

      Amazing Exhaust

      For my 07 Cobalt SS SC. The quality of it is outstanding, installing it was honestly pretty easy, everything fit perfectly. I got it with the resonator and it gives the car a deeper throaty sound, definitely louder than stock and overall just sounds amazing!
