I tried to install the Heddman Y-Pipe to the Heddman Shorties that I had purchased. The problem is that the passenger side hedder dosen't mate up to the Y-Pipe. Did any body run into this problem and if so what did you do to correct it?

I'm doing the same thing right now, just inside cooling off a bit. I got the passenger side lined up, but am having a heck of a time on the driver's side. doesn't seem like the little cut piece of flanged pipe goes far enough into the rest of the y-pipe to make it line up correctly. I'm going to cool off and try a different approach, like bolting up that separate flange first and then slipping the y-pipe over it and working on the passenger side after that.

What part did you find most difficult about installing the headers themselves? The biggest PITA for me was modifying my a/c bracket to mount. I ended up just cutting one leg off. Seems to work so far.

Keep me updated, I'll check back here later....

We really did not have any problems. We took out all the emission stuff because we installed a LT 1 manifold. But we did have to unbolt the motor mount to jack up the passenger side of the motor. Now the only problem we are having like I said in the above post is the Y Pipe will not mate up on the one side once you start to bolt the one side on. Its hard to believe that some guys on the board installed the Heddman Hedders and the Heddman Y Pipe and they did not have any problems. Come on guys your help is need here.

Yah, no kidding! Actually, my passenger side header went in very easy (I've already taken out all the emissions stuff years ago), and the driver's side just needed massaged a little by just barely moving the engine up in it's cradle, maybe 1/16"...then it just settled in. The problem I had with the y-pipe was the aftermarket "soft metal" gaskets I bought for the flanges. The 3 holes for them needed elongated so the bolts would maintain their attituted towards the y-pipe flange. After I wormed out the holes, we're talking about 15 minutes to get them bolted up tight and the cat on. I still need to finish breaking the exhaust pipe from over the axle (the rust has already done most of the removal work on the piece of junk 2 1/4" pipe. Then I will hang the new pipe and drive it a couple of miles to the performance shop to have an adapter made to bolt up the cat to the pipe and we're talking done install. I might have them weld all the joints together while it's there, so I'll take my muffler along for the ride.

I sure hope I can feel SOTP results for this mod.

Next mod is a 3:42 rear end out of an 86 Firebird V6. I'll probably wait until the heat goes away before I do that one, even though I hear it's alot easier to swap whole rear ends than do the exhaust.

Let me know how your install goes and what you had to do to make it work!!! Good luck!

Lasher 350: I did not see how you bolted the Y Pipe on. Unless I'm missing something in the Post.

woohoo, im about to tackle a pair of these myself, as soon as theyre back from jet-hot. what exactly did you have to do to the a/c bracket? any other problems you can warn me about?

lasher_350

I'm getting ready to head out there again this morning, I'll take some pictures of what I did and post them here soon.

Now I'm having a big problem with the catback pipe not going over the axle, and I'm about tired of it, so I'll be taking it down to the exhaust shop asap and let them do the "easy" stuff! ha ha

I tell you, if I didn't have 3 kids to watch all the time, the install would have been a lot quicker. As it is, though, I only had about an hour a time to work on the car, so it's lasted way longer than it should.

Anyway, I'm out to get the pics! Later

Here's a couple of pics, but I think my setup is different than yours, KagA, as my a/c is on the driver's side....but anyway, you'll get the idea. I had to chop off one ear, but it is just as stout as before.

my a/c isnt in the way at all. the only problem clearance wise to me looks like the heater box. im removing the smog stuff, so its not an issue. will i have to take everything off doing with the heater box, or just the box itself?

lasher_350

Unless the heater boxes have changed drastically, you shouldn't have a problem getting the header in there, especially if you are dismantling the smog equipment. The header should be able to be angled in from the front and slide right back into place. My starter wasn't in the way either, but I did take off the wiring to it so I could reroute it a little safer away from the headers. Once you get the AIR pipes and stuff out of the way and get that last bolt out of the back of the manifold, then it should be smooth sailing....but you'll need a short wrench to tighten the back bolt on the headers for sure...not much room back there.....hope that helps some....


On a good note, though, mine is completely finished. Took it to the exhaust place today, and they suggested I return my catalytic coverter and go with one of their "straight pipes" as they called it....lol It is ULTRA FLOW!!!!
Sounds sweet with the Terminator in the back. I'll have to go and tighten header bolts tomorrow after a bit of playing this afternoon.

I am having some black smoke coming out the pipes now, is that indicitive of a rich mixture, or just from the new pipes and what not? Any ideas? Thanks.
