Best sounding/most expensive- Corsa and B&B

Best sounding/affordable/overall performance- Magnaflow

I have the long (26") round Gibson muffler, 3" pipe in and 3" single pipe out. Has worked well for over 200,000 miles.

Just a nice tone in the front seat. A little more noticeable (louder) in middle and rear rows of my Suburban.

I have a '00 Silverado.. I just took off the muffler. I just had them put in a y-pipe so that I can have the dual pipe comming out the back. It sounds awesome and you do not get the re-verb cab noise like you get with performance mufflers.
