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.

Sounds amazing

This was super easy to put on! It took me longer to take the old one off than it did to put this on. Sounds amazing and super fast shipping! Great design guys never had something fit together so snug and easily.

Longest part of the instal

Longest part of the instal was getting my old exhaust off. Took about 30 minutes putting this one on. Sounds great!

Great sound

I have had the cat back in for over a year and the pipes still look like they are in great shape! The sound with the resonator is great, I am glad I splurged for the resonator.
