Chevrolet Flowmaster

I have a 1993 EX cab 4x4 and need to know if anyone has tried to put a flowmaster duel out the rear on it. Do you have to do anyting with the spare tire. Is the American thunder system loud while driving down the highway.
thanks

I have a Flowmaster 40 Series on my 93 standard cab. Its a duel outlet, and one pipe goes pretty much striaght out, and the other goes around the Gas tank. Its not too loud on the highway either(40 series is supposed to be the loudest, i think.)
Hope that helps out a little.

I work at a shop in florida where we install FLOWMASTERS reguarly. We never have problems with tails even with hitches and spares. Deltaflows sound real good and do not have the drone at highway speed. :bigthumb:
