"The tech support rep recommended this muffler for my one ton Chevy Van. It was a perfect fit, the muffler shop I chose had no trouble installing it. They made a new full 3" tailpipe to match the muffler output.
It's nice to be able to hear the engine running now, the noise inside is audible but not too loud. The sound outside is best described as muscular & throaty. Great sound.
It is too early to tell if my gas mileage has improved or how it performs pulling my RV trailer.
I also added a K&N air filter." —Paul G from Sherwood, OR bought a Flowmaster 70 Series Big Block II Mufflers for a 2002 Chevy Express.
