Holy Mother of God! Installed the Corsa Extreme System this Saturday and its a freakin dream come true! Totally different sound... almost has a higher/raspier sound. Reminds me of some of the high end mustangs you see floating around. Cant hear anything more inside than when it was stock... hell, not sure why anyone would buy the Corsa Sport, cant imagine it could be quieter inside. But roll the windows down and it sounds freaking great... and wide open throttle and it screams! Love it! Worth every penny!
The MBRP shorty sounds like el cheapo system specifically for high school kids who just want loud.... Corsa sounds like something with real design and is meant for someone who wants an exhaust that sounds like quality... the sound precisely toned to complement the truck. Best way I can describe it.
Also... another bonus... no weird idle! That MBRP system made my truck idle high at completely unexpected times... like at a stoplight without my foot on the gas... very odd.... it'd just shoot up to 1k rpms out of no where. Like the engine was confused. Now with the Corsa, it idles perfectly just like it did with the stock system.
Again... worth every penny!
