Hello All,

I have a 2005 GMC Yukon XL SLT 1500. Everything is stock on the truck except for a K&N cold air intake. I'm looking to upgrade a couple things. First off my exhaust system, again everything is stock, but I want a louder outside sound. Give it a more throaty and deep sound. At the same time I don't want a huge resonance inside the truck. I'm looking toward the Flowmaster Series 40, the Super 44 series, the Super 40 series, and lastly the Delta 40. I need help choosing. All comments and suggestions welcomed.

Secondly im looking to add a brush guard, or a grille guard to the truck. I've searched around the internet and took some suggestions from my mechanic and friends. They all suggested Westin Grille guards. I'm looking for feedback to see if this is the right choice and/or maybe there is something else out there. I want the guard to cover the headlights and All black (No chrome or colors at all).

Again all feedback and suggestions are welcomed.
