    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, 2005+ 2.2 & 2.4 liter Cobalts.

    When I pulled it out of the box all I could notice were the phenomenal welds. Installing it was upper easy, just lifted one side of the car and sprayed some WD-40 on the hangars. It sounds so good, and is a great medium between stock and loud. I highly recommend this exhaust

    Sound's amazing.

    I run this with stock headers, a old 3inch catless downpipe, and with the resonator delete. There is a tiny bit of drone\buzz around 4k but it's not that bad in my opinion. My main complaint is 4th gear 2500rpm sometimes has drone sometimes it doesn't. But this will give you a lot of good pops and crackles on deceleration with the right tune. And sometimes during shifts you'll get a nice big pop. 10\10
