Forum rules states that you gotta post a price. Anyways to let you know what you're up against:
There's a stock 2015 exhaust going for $150:
2015 OEM Exhaust - Excellent Condition - $150 Houston
Another stock exhaust for $100:
Stock exhaust Bose headunit
An exhaust for $200:
Stock exhaust & intake
Just giving you a range of prices, which go from $100 - $200. Now I'm not suggesting you should put prices around that, you're more than free to price it at $777. But just know that stock exhaust isn't really high in demand unless there are folks trying to go back to stock. GLWS
