I have a 1984 trans am and it has a trans planted 350 from the early 70's, I need some part numbers for a set of headers with no air, everytime I try to find headers to fit my app the people tell me (well the car came with a smog pump so these are the headers you need) No they are not...my car no longer has a smog pump...lol! I also need a part number for a 3" Y pipe, I plan on having a 3' system all the way back with a flowmaster dual 2 1/2" out that my local exhaust shop will install.

 

There is one outfit that makes a true 3" y-pipe for our cars - Hooker. And, the only way to get that y-pipe is in a set with their 2055HKR shorty headers.

Yes, they do have the A.I.R. fittings. Big deal. Don't need them? Cut them off at the weld, weld it shut, and use a die grinder to grind off the piece of pipe sticking inside the primary tube. "But I don't want to pay extra for something I don't need," you say. Well, if you want headers with a 3" y-pipe, this is going to be the least expensive way to do it.

Let's see why that is: You want headers without A.I.R. and with a 3" y-pipe. Okay, start with Hedman 68470 headers, no A.I.R., no y-pipe, $145. Great, they make a y-pipe for them, 14178, $120. Now you're at $265, but wait, the y-pipe is only 2.5" outlet. Okay, you get the Flowmaster 2.5"-in/3"-out "Y", that's only $40 - just cut off the "Y" from the y-pipe and put that in, then a 3" mandrel bent elbow over to the cat - well, that's another $30. Oh, you don't have a MIG welder, guess you'll either need to buy one for $400 or take this all to an exhaust shop to have them do it. Personally, I haven't gotten out of an exhaust shop for less than $100 for a simple job in years, one more complicated like this is more likely to be $200-$300. Hmmm, how much were those 2055HKR's again?

Same story for Hooker 2460HKR's and their joke of a y-pipe.

Get Hooker 2055HKR, whatever else you need from there on back using '86-'90 TPI as the application for what you order.

 

Thank you for the great info...I guess it would be alot cheaper to cut the air tubes off and weld them. Do you have a part # for the 3" y pipe from hooker? I tried searching google with no luck.

 

It comes with the headers when you order 2055HKR.
