I have a Flowmaster and if it is a muscle car sound that you want then you cant go wrong with it.

 

I found a setup on ebay that I think is very reasonable.

This guy has several different setups to choose from. I have my eye on the delta 40 with the rolled tips. Shipped its only $250.00 and the autobody shop guy at the High School that I teach wants his kids to do it as a project. So I could save the install cost.

Yeah going to have to disagree with you there. If we want to talk about free flowing mufflers: the Flowmaster is NOT a free flowing muffler. It is full of chambers and baffles that stop and redirect the flow of exhaust gasses in different directions. Free flowing would be defined as a straight shot through the muffler similar to a straight pipe. No one can argue that baffles flow better than a straight pipe. The Magnaflow is a free flowing muffler because it utilitizes a perforated straight pipe to move exhaust gasses through. The muffling is done with the packing material around the pipe.

Second, both mufflers DO NOT lose torque. Torque is retained and improved by acheiving maximum exhaust gas velocity. As seen in the description above, it is obvious that the Magnaflow provides superior flow and therefore superior exhaust gas velocity. That is, of course, unless too big of pipe is used. A stock 4.6L or 5.4L with 3" true duals regardless of muffler is going to have no torque. The reason for this is that the velocity of the exhaust gasses is slowed down by too large of pipe which lowers the pressure and the velocity of the gasses. Exhaust gas velocity is also harmed by the baffled and chamber design of the Flowmaster. There is a chart floating around this website showing the CFM flow of different mufflers and lists the two chamber Flowmaster (40 Series) at 233 CFM. The Magnaflow flows in the 400 CFM range. In comparison, a stock muffler flows 150 CFM. While no one argues that Flowmaster is an improvement over stock, for the best performance for your dollar the Magnaflow is your best bet.
