Headers: AEM Brute Force or Thorley Tri-Y?

[DaUsedMCR]

now that i just installed my catback and a vette servo, my next mod i think will be some LT headers. i am stuck between the Thorley Tri-Y's or the AEM Brute Force (which im leaning to because they come with Hi-Flow Cats and Y-Pipe, but are a bit pricier) i have a pacesetter 3" ORY in my garage that i was gonna use for my Firebird, but headers and turbo dont mix well, so i sold the headers i had. and it should work on the Tahoe, id just have to get the cats welded on. which headers do you all think i should plan to get?

LPP's

the only place i could find LPP LT's are their site, but they are for trucks with no EGR, and im pretty sure mine has it.

truck and suv headers are same.
Have them weld on EGR fixture.

i know they are the same by "trucks" i meant trucks/SUVs in general. i called a shop and they quoted me $300 for the header installation and $75 to put on the EGR fitting. another question i had was, since the LPP's come with no cats, will my truck sound like crap or rattle with my magnaflow exhaust? ive heard people say they can sound bad with no cats

use your oem cats

dont use the ORY..

wont the OEM cats block up the flow and hinder performance? also, i know the LPP's are stainless, but how are they for underhood temps?

very good, like the higher more expensive brands...the stock cats dont restrict as much as you'd think
