Just picked up my 14 Sierra All Terrain last night

[Sdb33]

Hey there, new to the forum but there seems to be a ton of great info out here for a new owner like me. Just picked up my 14 Crew Cab All Terrain in iridium metallic. Had the dealer do a 2 1/4 inch level in the front, 1" block in the back, 33" Toyo ATs, and a Flowmaster cat back exhaust.

 

We'll the truck looks amazing but the exhaust is terrible. I reached out to get the model they put on and will add tomorrow. At start up and when accelerating it sounds great but between 1500 and 2000 RPM the drone is unbearable. After the hour and a half drive home on the highway last night my ears were ringing, couldn't hear, and had a terrible headache. Even driving through town 15 minutes back and forth to work today my head was pounding.

 

Has anyone else had a similar experience? Next step is to try to get them to fix it or return to stock but I'm guessing they ripped out everything and will charge a ton. Want some sound but this is ridiculous.

 

Greatly appreciate any advice anyone may have.

 

Thanks
