I cant seem to find any company that really make anything exhaust wise for the 8100 in a suburban. Mean time my duddy brand got a flow master put on his 8100 and thye had it in stock at the local muffler shop. The guys said : the exhust size on GM trucks are the same for all 6.0 ltrs and 8.1ltr trucks...

So after he said that it got me thinking if this cat back for corsa performance for the 07 model esculades and denalies would work? It sound mean as hell in the sport option...
