Hooker -vs- TPIS Headers
I understand both the Hooker 2149's and TPIS headers will work well on my 86. I'm leaning toward Hookers simply because I can eliminate that crappy "clamp" style EGR tube connection that is on my stock manifold. The Hookers supposedly have a two bolt connection if I buy a later version EGR tube. Is this correct?
Also, are O2 bungs provided on both styles?

Hookers you need to get a Y-pipe for. The TPIS includes the Y-pipe and I know has the sensor bung installed, both the emissions and non-emissions versions. Don't have Hookers so can't comment. But pretty sure they do.

Hookers have the 02 welded in the number 7 primary, which some have used without any problems. I put a heated sensor in the Y pipe on the passenger side (more room there).
Yes the Hookers use a bolted egr (later style) pipe. Other differences are they also have a flange connection to the Y pipe instead of the slip fit that TPIS uses.

Re: Hooker -vs- TPIS Headers (1MoorTym)
Is the flanged connection to the front Y better than a slip fit? I've heard ceramic coatings can cause trouble with slip fits. What's the Chevy part # for the later style EGR tube? Can I buy one anywhere else?

Re: Hooker -vs- TPIS Headers (bradvette)
A few of the Hooker header bolt holes are very close to the tube OD's.
IF I bought them again, I would weld on a tublar extension over the bolt hole so it sticks out past the bend in the tube so you can get a good grip on the bolt.
You will be glad you did this little mod belive me.

Tell me more about this. What do you mean by a "tublar extension"?

The OD would be @ 3/8" and the hole would be clearance for the 5/16-18 header bolt, the length would be @ 1-3/4 long and would stick out just past the bend in the header tube so you can get a wrench on the bolt head,,, some headers already have these welded onto them.
The way it is now 3-4 of the header mount hoels are too close to the header tube so you cna only turn the bolt @ 45 degrees,,,, I tried using socket head caps screws (SHCS) and they work OK till you get back to the passenger side rear bolt, then virtually nothing can be used back there to reach a bolt head. I cut off an Allen wrench and slip a 5/16 boxed end wrench over the allen piece and then use a pipe to crank it down.

Re: Hooker -vs- TPIS Headers (geezel)
Shouldn't you mainly be considering your application vs. header size?
Hookers have 1-3/4" primaries; aren't the TPIS only 1-5/8" ?
On a less modded car the 1-5/8" are usually better, especially for low and mid range torque.

Re: Hooker -vs- TPIS Headers (gcrouse)
ld85, I understand what you explained about the hookers headers and adding a tubular extension to give you some place for the bolt... but do you know if the TPI's are ok for this?
I plan on putting on a set of headers on my car this summer, but I don't want to do any welding on my brand new headers, "especially if their coated"
