Headers

[Keewatin427]

Has anyone installed headers on their ZR2? if so, was it involved, did you DIY or take it to a shop? A model you recommend? Any noticeable HP gains?

Not on my Z but on my 2020 HC. Haven't started it in a while but here it is after sitting in the garage for 2 mths.

Headers and S-type with the GM intake

Did it mah self. Feels moar fasters. Off the line with Denali's and other 6.2 Silverados I pull about mid bed infront of them. Haven't tuned it, on stock cal.

Need more details, please
Longtubes or Shortys? I'm gonna guess short tubes if no CEL on stock tune.
Brand?
Tube Dia?

PART # 1850S-2JS

Ceramic coated

Shorties

The truck had about 1,700 Miles when installed, currently at 53k never threw a CEL.

I did get some hesitation about 3 months in, which I thought was bad gas but it ended up being one of the plug wires that had managed to relax on one of the header tube's. Purchased a new set of OEM wires and a set of insulator sleeves for the wires and never had a problem again

This is what I want to do along with the AWE Tuning 0FG Catback to have true dual exhaust, but will more than likely require a tune.
I am not quite ready to go down that rabbit hole yet.......
