2.5 inch Stainless Cobalt Catback Exhaust

  • 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 as a stock replacement. 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 (LSJ), 2005-2010 2.2 & 2.4L Cobalt's; also fits 07-10 Pontiac G5.

    Performance parts as the name states!

    Our local mechanic spaced out the exhaust header and pipes for my son’s cobalt ss and he did not steer us wrong. The car performs so much better and the parts quality is very good!

    Best Bang for the Buck

    Excellent fit and workmanship. The sound is throaty, without being overly loud. Virtually no drone ! I highly recommend

    So quiet

    Big difference from my old stock exhaust. Super easy to install... with a friend. But still super easy, and sexy.

    Very happy

    I will only be buying parts that are sold by zzp whenever I can. Love the sound, as this is my first time having a non oem exhaust I had so many questions all have been answered quickly and to my satisfaction. Non resonator with muffler, I also got new hangers which I am very glad to have done as the oem had been getting rotten and difficult to remove. I was also very surprised at the size of the tailpipe at 4" its impressive.

    Great and affordable product

    Exhaust sounds great especially compared to my old leaky one. Affordable, shipped quickly, and no missing parts. Couldn’t be happier!
