got a set of tes headers for 91z . i have been hearing they aren't so good they aren't on yet but does anybody have an opinion on them and whether any are better? never put headers on before so i'm looking for something i wont have a problem with fit. thanks

 

I didn't really care for them. They were cheapies to use in the meantime while I was looking for better ones. I used SLP 1 3/4 ones but you might use the 1 5/8 one if you are not going too far with your mods.

 

SLP

 

SLP...awesome warranty mine still look great after a year...Worth every penny.

 

SLP headers are going on my car this afternoon FWIW Along with their included Y-pipe and that goes into a new 3" 40 series flowmaster right where the cat used to be located. Dumped right there onto the ground

I wonder what kind gains i'll see when I hit the button hehe I hope the nitrous likes it's new exhaust path!

 

Alright. So SLP it is for me as well, so why dont y'all help me find them cheap. And when you say included Y-pipe you mean "necessity inclueded" right? Or is there a package you can by everything you need? Tell me prices and where I can get them. Thanx.

 

Try www.slponline.com for the SLP headers and everthing else you may need for installatiom. A better option then some other sources. Also may be cheaper or on sale. My opinion.

 

Keep your eyes peeled for group purchases on the SLP headers. They come up on Thirdgen.org (exhaust board) on occasion and you get a pretty big price cut.

 

Does anybody have some SLP's for sale? I kinda want SLP but I'll take some other ones if they're good enough. Is there anyplace you can buy used headers for cheap? I mean, used ones are just as good as new ones right?
