ISO 1997 5.7 LONG TUBE HEADERS

[grantclark1990]

Hey gang! I’m sure this question has been asked a LOT. I’m looking for some long tube headers for my 97 Yukon here. The truck is currently tuned by Blackbear performance, does have trans mods, shifts like it’s being chased, and currently gives its sound through a magnaflow straight through muffler. Otherwise stock!!

I’ve done that. I still have yet to see any straight answers.

Here is a write-up from someone who did it.

Perhaps a moderator will move this thread to the Exhaust sub-forum.

TBI headers work fine if the EGR has been deleted in the tune. Bolt on and go as I did in my truck.

I just so happened to find a link to these from an old YouTube video from years ago. At this point I think I’ll try them out! I also plan on keeping the O2s and just using the spacer mod for the rears. The EGR will be gone and deleted out though by Blackbear for sure.

I have a set of long tube PaceSetters I bought local off marketplace. When I SAS my Yukon, Im not sure they will work. Plus I might swap the extra 454 I have into it....but, that will be a couple years at this rate...
