Got a video? I'd really like to see it. I do NOT want my Tahoe loud, I have my truck for that. However, I did order an AEM CAI today and I'm getting an in-person BB performance tune 4/28, would replacing the muffler be a big gain?

 

[ChrisAU]

Bueller?

muffler gained 12hp with nothing else done at wheels on a buddys truck.

Stock 6.2 muffler is restrictive we cut it up and baffles everywhere

Hmmm, I wonder what the noise level would be like keeping the stock resonator on a 5.3L?

 

[Smokymance]

Tony, you got a booty shot of what the rear looks like without the resonator? i wanna maintain that stock look to it, and sorta like the "resonator" look back there....

 

[NORCAL SS]

no i dont just looks a lot better no resonator in rear

Contemplating the same thing before the tune...

Magnaflow and delete?

 

[NORCAL SS]

please check vids i posted its fine without resonator no drone.

 

[Smokymance]

So what you got hanging back there? nothing at all if you took the resonator off?

 

[NORCAL SS]

turned down after the axle just cut the factory pipe works out perefect

 

[Smokymance]

Sounds like a deal...ill be getting the muffler and an intake for it...any recommendations?

 

[NORCAL SS]

i have the volant on my truck (normal filter) and i like it. Im going to tune it next but for intake/tune and im 2wd i beat my buddys 14.6 mutang.

 

[Smokymance]

I was thinking of getting the Banks Power one just cause i havent seen anyone with it ...just to try it out...just got the tune few weeks ago and you are right, these trucks can spank pretty good amount of sports cars out there!

Old thread I know. I just got this muffler. Thanks for your info here.

Now to figure out how I want to install it....

 

[Mickey_7106]

does anyone know if the '09 5.3 has a 3.5" exhaust?

does anyone know if the '09 5.3 has a 3.5" exhaust?

Hey @NORCAL SS, I got a 12909 muffler and there is no way it will fit with the center/offset rather than offset/offset. Is there a different muffler that needs to be used for an ESV? I have a 2008 Escalade ESV and the 12909 is just not able to line up. I long ago got rid of the resonator for the SLP piece, but the shop had some 3.5" straight pipe, but it would need to be some janky angles to try and make it work.

 

[langsbr]

Or, does anyone have an installed picture that's not at an angle? The only pictures I've seen are at a goofy angle where you can't see how anything sits.

I can't believe I'm in hillbilly SC and can't find a shop that can easily do this.

Umiliffler has to be instalked at slightbangke like my video shows
