Been thinking about getting an exhaust system upgrade for my 87 K5. Looking at a Flowmaster Force II system from Summit Racing. It involves a two chamber muffler, a 3' intermediary pipe and 2 1/2 " exhaust pipe. The other system I have been thinking about is in LMC. It utilizes the stock manifolds and is basically dual exhausts. I pull a two-place snowmobile trailer and do alot of mtn driving so torque is needed. What do these systems sound like?Would the system from flowmaster suit my needs do ya think? I am leaning towards it. The prices are about the same.
