SLP Loudmouth II cat-back for 2005-07 Cobalt SS.

Bolt on a Loud Mouth II™ catalyst-back exhaust system from SLP on your 2005-07 Cobalt SS for significant horsepower gains over your stock restrive exhaust system. The tone is deep and powerful letting everyone know you're coming, with an aggressive rumble. The secret to the system's distinctive sound and performance gains is a polished stainless Loud Mouth II™ bullet-style muffler, stamped with our SLP logo. This system features a polished 4 double wall round tip, providing you with the ultimate Cobalt look. The modular design gives you flexibility to change to our louder Loud Mouth™ resonator (# 31062). The rest of the exhaust system is hand-crafted from 2.5 409 stainless steel, comes complete with hardware, detailed installations and is covered with our Lifetime Warranty.

Loud Mouth II™ catalyst-back exhaust system for Cobalt SS features:

Limited Lifetime Warranty
Hand-crafted from 409 stainless
Easy bolt-on installation
Modular design
Polished 4 tip

will not fit non-sc or non-turbo

Applications:

2005 - 2007 Chevrolet Cobalt

SLP Exhaust Type Descriptions/Definitions/Details: (use as a guide to the exhaust system on this page for details about the muffler type.)

Model	Type	Sound Characteristics*	Noise Level*
	Bullet-Type Open Resonator (or muffler delete)	Extremely aggressive; powerful high- and mid-range tones with moderate resonance
	Muffling, Bullet- Type Resonator	Similar to original Loud Mouth, but with a throatier tone and reduced resonance
	Straight-Through "Traditional" Muffler	Deep, rich, and mellow; minimal resonance

* Volume and sound quality will vary based on engine and exhaust-system specifications. Loudmouth also refers to some systems without any resonators such as the 2010 Camaro Loud Mouth and the 2005 Mustang Loud Mouth Axle backs where the mufflers are removed altogether. Images below are representations in order to better understand the differences.
