Is 18 with all the mods you've done? What size tires do you have? I've currently got some lightweight falken ziex 275/70r16 tires on stock saw blade z71 wheels and can get almost 19 goin 75 in the Central Valley no ac and one widow not rolled all the way up haha

 

I realize you know about the headpipes, you stated so in your 1st post.

If you need to pass smog, run stock manifolds, then swap after. Shorties are legal so long as your connect the AIR and EGR.

If you have questions about a product, take a look at the products website. It will tell you what you want to know.

Have you heard of L&L mid lengths? They're a little bit cheaper then the thorley's a but still have the egr provisions I need. For guys seem to love them for their trucks. Might just have to take the plunge an find out.

 

No I havent, the best midlengths were the TOG's. You can see them from time to time in used form of course. They had crazy thick flanges. and were leagl in Cali.

Good luck man.

Thanks for the help. Is there any forum that I'd have a better chance of finding these headers at? Fsc or gmfs perhaps?

 

Not that I know of, kinda hit or miss, I havent seen a set in a while now.

What did they go for when new?

 

It looks like using the 3/4 ton the rear O2 sensors amy need some extra length to hook up.

 

Yeah I noticed that as well... Hopefully that doesn't turn out to be the case

 

I don't remember, it was over 10 years ago now. They did have nice thick collector and primary flanges.
