Pacesetter Armor Coat 72C2264 longtubes

[FATHERFORD]

Has anyone installed these on their 5.3L tahoe?

Looking to install these and some high flow cats(leaving the factory cat back) on my 03 tahoe. Wondering if anyone had any good results?

The stock cats actually flow pretty darn good. You'll be throwing money away by buying "Hi flow cats".

Good headers especially for the money. I'd wait a bit and check the reviews on these LPPs

My cats are going next week hopefully...should be nice and loud with the longtubes
