    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.

    Excellent product

    Everything bolted right up. All hardware included and hangars in the correct locations. Tailpipe is slightly bigger yet looks stock to the untrained eye which is what I wanted. Sound is just right with 2.5 downpipe and shorty header. Great product! Installed on 2006 LSJ Cobalt.
