2004 Silverado 5.3L Comparison of Stock Length Y-Pipe vs. Equal Length Y-pipe with Borla ATAK

2004 RCSB Whte 4X4 Silverado
Stock 5.3L/4L60E
S&B CAI
Stock exhaust manifolds
Stock length y-pipe with cats removed vs. equal length y-pipe with cats removed.
Single 3" pipe from y-pipe into Borla ATAK Cratemuffler to 5" tip behind right rear tire.
Borla ATAK Cratemuffler
Borla P/N: 400844
I modified the stock y-pipe by removing the cats and making the passenger side of the "Y" the same length as the drivers side in hopes of reducing the clap and giving it a cleaner exhaust tone.

Probably the best exhaust comparison video ive seen

[@oklahomagoochgrabber7500]

saw someone in a forum mention this dude and how he had 100s of different exhaust comparisons, i was not disapointed

[@mattofearle]

Lol. Hopefully they help and I have more to come possibly. What forum?

[@stoichiometry147]

Great comparison. Definitely would need a resonator (perforated core glass pack) before the Atak muffler to get rid of that earpiercing rasp.

Great video!

[@televisionpilot3551]

Great job man. What camera are you using? And what were you using on the videos were it was mounted to the rear bumper?

[@mattofearle]

Cell phone for most videos unfortunately. Samsung S22 Ultra in these, Motorola in the red truck videos and GoPro on the bumper.

What’s louder the borla atak Or the corsa

[@mattofearle]

I have to say Corsa Pro is louder.
