This is our ZZP cat back exhaust for your LSJ/LE5.

• Stainless Steal
• Mandrel Bent
• Optional Resonator
• Polished 3 Chamber muffler
• 1/2" Hangers in all OEM locations
• Includes all required clamps, gasket, & bolts
• Direct bolt in when used with our 3" 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. Remember that this is a 3" exhaust, it will be louder than stock. Also it will be even louder if you do not chose the resonator option and run a cat'd downpipe. This is a very good sounding exhaust when you order it with the resonator and muffler options.

Fits the 2005-07 2.0 (LSJ), 2005-2010 2.2 & 2.4L Cobalt's; also fits 07-10 Pontiac G5..
