Borla part number

[Flyboygt]

ive been searching for awhile and can’t find it. I’m looking for is a part number for the borla touring muffler, only, for the 17 Tahoe 5.3L... I don’t want to spend 1k on a cat back just a better sound.

Thanks for the help

I’d like to know the answer to this question as well.

Ive been dragging me feet on this one as well. I thought Magnaflow was the way to go with only a muffler swap?

I dunno. I just know I like the sound of the Borla cat-back but I'm not paying a grand to be slightly louder with stupid chrome tips that hang lower than my step rails.

The muffler for the above Borla system is Borla p/n 55770, which is with one 3" inlet and two 2.25" outlets. If you're looking for a single 3' outlet, check these:

Just picked up a 40359. I’ll report back in a couple weeks when I have a chance to get it welded in.

What about your resonator?

Leaving it. I'll have them remove the flapper (AFM is disabled through my tuner) but I want the resonator to stay. I don't want much noise at all, just a slightly lower tone.

Me too, curious how this will sound when you are done.
