well i just got rid of my silverado w/no warrenty and bought a brand new colorado but i was wondering about warrenty information i have the extended one but what i was wondering is it i do aftermarket stuff like exhaust, chip, intake, and header will that void my entire warrenty or just the warrenty on the parts i replace

I used to work for a Pontiac Buick GMC Cadilac dealer and if we did mods that voided the GM warrenty, we would provide coverage ourselves through the dealership.

We jacked up alot of 2500HD duramax 4x4 trucks.

good advice!

it should only void the aftermarket parts. the dealer has to prove that the after market part did the damage. some where on the sema website you can find the magnussom moss warranty details
