Straight thru mufflers are not a must, they certainly help in making more power but are not a must. There was a time when people ran flowmasters with turbo kits and had no idea they were a bad thing to run. Plenty of people made 400rwhp or more with those mufflers and had no reliability issues because of a chambered muffler. Heck I know of one car that made over 1000rwhp with 3 chambered flowmasters on it and the cool thing about that car is it was VERY QUIET. Not saying to go run chambered mufflers, just pointing out they are not a must by any means.
