Sport / 3.0 in Cat-Back SSE 4.0 in Twin Tips | 14-19c Silverado Sierra 5.3L 153WB (14874)

2015 Sierra cat back

Install was easy and simple. The twin polished tips are nice. Only rate as a 4 because other sound clips seemed to sound a little more aggressive than how mine turned out. Definitely a lot more aggressive than the stock exhaust!

New exhaust

I would give you 5 stars, but I’ll have to go with 4. Product is AWESOME! However, I was missing the head pipe once I opened the exhaust system. However, I filled out the correct warranty I formAtion -per my phone conversation with Matt. Once I did this, you guys stepped up and sent me the missing component. Thanks for doin lg the right thing and taking care of your customer. In today’s world, it’s HARD to find companies that stand behind their product and deliver. Thank you Corsa!

Best exhaust for gm trucks

I work as GM tech and have installed/heard many exhaust setups and they all have horrible drone, never fit properly, sound like total garbage when it goes into v4 mode....but not the corsa, I picked up a sport system for my 2016 Sierra Denali 5.3L and it took me all of 20 minutes to install it, the fitment, the build quality and the sound is top notch, the shipping was also extremely quick. The exhaust only drones slightly at 1800rpm but once u get up a few gears you can barely hear it which is very nice when driving for longer periods of time. No doubt about, best exhaust u can buy.
