I recently bought a 98 Yukon Denali. So far I love it. It needs a little TLC but will be well worth it. I was wondering if putting a Cold Air Intake on it would be a good idea. Also if putting a new exhaust on. I've messed around with cars but haven't messed around with performance. So i'm a noob. As some would say. Any help and advice would b awesome. I know i'll be posting on here and I'll post pictures tomorrow.
