    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.

    Sounds nice!

    Fitment was great, all went together super easy. The tip doesn't look oversized at all and it has a nice deep sound with the resonator. Also increased my mpg by 5 mpg. thinking the old one was plugged. Would definitely do it again.

    10/10 sound, quality, and figment!

    Absolutely love the exhaust. It provides a deep sporty sound without being excessively loud. Completely drone free inside the vehicle. Top quality parts look great, fit properly, and were very easy to install. The package arrived very quickly and the exhaust parts were very nicely packed in the box. Will definitely use ZZ again if I need anything else for my Cobalt!

    Love It

    I absolutely love it, especially since I got it without the resonator. Sounds a whole lot better now!

    So easy to install

    I now have the full ZZP Exhaust system from the shorty header, 2.5” down pipe and 2.5” catback. Installed it on my 2007 Hhr LT 2.2 na. Took about 1 hr in my driveway that includes removing the OEM exhaust. It all bolted right up without a single issue.
