I'm running true dual straight pipes on my z71 right now with mud tires and a leveling kit and most likely getting a lift kit, but I thinking of putting mufflers back on to regain some mpg's, what's a better muffler for performance and sound?, I don't know much about muffler brands and which one is best for overall performance

Not another exhaust thread
There are plenty of threads about exhaust if you use the search bar. Bust or the most part I think majority of the guys on here are running dynomax bullets,borla xr1 or a magnaflow.

i have a flowmaster on mine and I love the sound, mine is still the single into one then dual flowmasters after that

but just get you some Thrush, or flowmaster, borla, they are all really good. you wont be dissapointed in either

Magnaflow, flowmaster, borla, they all flow well you just gotta find which one will give you the sound you are after.

just put a borla pro xs on mine and is quieter than i wanted but has a good tone. i like the dynomax bullets i had, my favorite is still the slp loudmouth.

any straight flowing muffler for max flow. round ones and shorter case tend to be louder with oval longer case ones being quieter.
