Doug Thorley

I had the Gibsons on my Tahoe and they didn't do ANYTHING for performance and leaked like hell. I wouldn't get headers unless you go with the Thorley's. You should be able to get them thru Summit.

search dood... seems like this is talked about on a weekly basis

however... go to www.autoanything.com, register for the email reminders, they email out 10% off codes + free shipping like once a month or so it seems. i got my thorleys in nickel chrome finish for $380 or so to my door. they carry the ceramics as well.

they emailed me a 10% off code today actually :D

mind you, they arent LT, they are a mid length header for the 5.7 L31... they come in shorty and LT for the NBS

How is the nickel chrome finish holding up?
And autoanything.com says the discount coupons don't apply to the headers. I wish i could get a set for 380...

wierd... thats what i paid for mine... about a year ago. bdz71 bought his from there too with the discount as well i believe.

the finish is fine... they turn blue and have stayed that way, granted theyre not exposed to nasty weather down here. they actually quieted my exhaust when first installed...

Pretty much every major brand has a set that will fit.
