Best Muffler/tune Needed?

StreetBobber09 · July 5, 2010

Ok I am really stuck on what brand muffler to get. I have a 2010 5.3l and it is very hard deciding. I have been watching videos and reading up. I would like to get dual exhaust however my I dont want to get even crapier mileage if thats the case with duals and no tune. Right now my rig is running 33's x 12.5

If I get the dual exhaust muffler should I really buy a programmer? My background is in motorcycles and I know when I did my bike I had to buy a power commander for it.

What brands do you guys really like? I have been looking at flowmasters but the more I see about them I hear that you really get worse mileage with their mufflers. I like the real deep exterior tone and loudness is not really a problem as long as it sounds bad ass and wont give you a headache in the cabin. <--Contradictive?

Thanks and sorry if this was posted 1,000 times before; I'm a newb here.

I like my Corsa exhaust. It's not true dual but I noticed some performance gain and almost 2 more mpg in my 2004 Escalade.

I am a fan of cherry bomb glass packs. They have a nice tone to them. I have heard that their regular mufflers are decent also. If you have a exhaust shop by, stop by and shoot the s**t with them and see what they say.
