If you're looking to give your Cadillac STS a voice that matches its sleek lines, this CORSA Axleback Exhaust is worth checking out. It’s not just about looking good; it’s about sounding good too. Thanks to CORSA's Reflective Sound Cancellation (RSC) Technology, you get that aggressive growl when you hit the gas, but without the annoying drone when you’re cruising. Seriously, it’s like they designed it just for those of us who love the sound of our engines without the headache.
This system is built to enhance performance while delivering a sound that turns heads. You can expect a 42% increase in flow compared to stock, which is pretty impressive. The 2.5-inch exhaust pipe diameter means it’s got the guts to let your engine breathe, while the dual rear exit adds a nice touch to the back end of your ride.
Now, let’s talk about the tips. They’re single 4-inch polished pro-series tips with a slash cut and a dual-walled design—definitely a step up in both aesthetics and durability. Plus, the whole setup is made from 304 stainless steel, so you know it’s built to last and resist rust.
Installation is a breeze. You won’t need to break out the welding gear; it’s a simple bolt-on process with detailed instructions included. And if you’re like me and prefer a visual guide, you can find full-color instructions online. Best part? It’s lightweight compared to the stock exhaust, which might just give you a little extra pep in your step.
Oh, and did I mention it comes with a limited lifetime warranty? That’s CORSA standing behind their work, which is always a good sign.
