Will stright pipes guzzle gas?
I got a 91 chevy LWB silvy. It has the factory cat on it with that cheap ass single inlet duel outlet muffler. The gas mileage is bad right now and the cat gets very hot. The heat from the cat has disclored the tranmission cross member. I figure it is bad and needs to be cut off. We dont have those emmisons test where I live so cutting it off is no problem. Duel stright pipes would be bad ass, but I heard that it can damage the valves, guzzle gas, and give you less HP. But I have also heard that it wont damage the valves, it will save gas and give you more HP. Whats true/false?
