Just wondering how "strict" either GM or aftermarket warranty with issues related to "tuners/exhaust" upgrades or changes?

Do I have to be concerned with a voided warranty as I do with the GM warranty?

any warranty we have delt with will only look after factory trucks...same set of rules as the base factory warranty it seems...

lifted trucks with related lift issues...not a manufactures defect and so on and so on....

in the end one cant expect a company to pay for a issue someone else created, lots of times in our area they send inspectors out, more so on the big dollar, commonly modified machines...
