This is our ZZP 3" cat back exhaust for your LSJ/LE5.
- Stainless Steel
- Mandrel Bent
- Optional Resonator (recommended for supercharged or N/A builds)
- 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 much louder than stock. Also it will be even louder if you do not chose the resonator option and run a catted downpipe. This is a very good sounding exhaust when you order it with the resonator and muffler options. However, we recommend our 2.5" catback for most builds, found here.
Fits the 2005-07 2.0 (LSJ), 2005-2010 2.2 & 2.4L Cobalt's; also fits 07-10 Pontiac G5.
July 2025 update: We have updated our muffler section with out new double wall muffler tip for a more modern look. New tip featured in product photos. Muffler delete is currently our old style.
