What is a good exhaust??
With TRUE duels you can actually LOSE power and torque in some applications. You lose low end torque with duels. A friend on mine has a late 80's GMC 1/2 ton with a 350. He did some research before he did his exhaust. He found out that the best power is made with a single 3" pipe. And he has it going into a single in duel out Flowmaster muffler. So, it has the looks of duels, but the performance of a larger diameter single exhaust with the awsome sound of Flowmasters
