If you’re looking to give your Pontiac G8 a serious upgrade, you might want to check out this CORSA Performance 2.5" Catback Exhaust. It’s not just any exhaust system; it’s designed with some seriously innovative tech that makes a real difference. With CORSA's patented Reflective Sound Cancellation (RSC) Technology, you can say goodbye to that annoying drone that often comes with aftermarket exhausts. Instead, you get a deep, aggressive sound when you hit the gas, but it stays nice and quiet during those long highway cruises.
This system is all about performance. You’re looking at a 68% increase in flow compared to stock, which translates to better throttle response and a bit more power under the hood. Plus, it’s lighter than the factory setup, shedding about 9 pounds—every little bit helps when you’re trying to get the most out of your ride.
Installation? It’s a breeze. You won’t need any welding, and it bolts right on with ease. The 2.5" exhaust pipe diameter and dual rear exit configuration mean it fits perfectly, and you’ve got those slick twin 3.0" polished tips at the back to finish off the look. The tips are slashed and dual-walled, giving it that polished finish that stands out.
And let’s not forget about the build quality. This exhaust is made from 304 stainless steel, so it’s built to last and resist rust, which is a must if you’re driving in less-than-ideal conditions. Plus, it’s made right here in the U.S.A., so you know you’re getting quality craftsmanship.
Here’s a quick rundown of what you can expect:
So, if you’re ready to take your G8 to the next level, this exhaust system is a solid choice. It’s all about that balance of sound and performance, and you’ll definitely feel the difference when you’re behind the wheel.
