will it fit

will the gibson super truck exhaust fit on my truck?? 97 s-10

the retailer should have lists showing if it will, or what system will.

Besides you didn't say what motor you have, or if it's 2wd or 4x4

its a 2wd 4.3L vortec

if i am gettin a exuast system should i get a new muffler also??

It should include everything you need, muffler if it is ment to have one.
