Reading this thread makes me feel so much better about the fact that I received mine a few days ago and am installing them this week...I ordered directly from BBK, had a couple questions that I emailed them and had my response within the hour. Great customer service, great price, lets see about sound/performance. I'm sure I won't be disappointed!

 

BBK is top notch.. I had their LTs and O/R H on my mustang.. Not one complaint!!!

Nice to see their products are holding up for you Wes

 

Ive been researching on what headers to buy for my z28 and because of this thread and the price of these headers im ******* sold.....

 

I'm about to start installing a set in a few minutes!

 

Drivers side done, passenger side to go. Drivers side was super easy going in. Basically the car is on ramps with the front jacked up higher on stands but the front wheels are still in contact with the ramps. Drive side went up and in no problem. I did not remove the steering shaft. I am taking a break here and there to cool off, and cleaning as I go so its taking longer than it should. I am also all by myself. So far getting the damn spark plug wires off without breaking them was the most frusterating time waster of the day. Hope to get the passenger side up and in here within a couple hours. Wish me luck!

Oh and so far the only casualty was one of the driver side manifold to cat studs. Damn thing turned about 5 threads before just deciding to shear, oh well. There is still plenty of stud left to get out of the manifold if I want to use them again.

 

Yeah, the install isn't bad at all, I probably spent just as much time routing the O2 wires, and installing additional heat shielding as I did with the header/y-pipe install.

 

I installed these on a 'vert and wouldn't recommend it unless you wanna do some extra work.

#1 The y-pipe didn't meet up with the i-pipe. I had to weld an extension on to make the connection.

#2 The tunnel brace/tranny brace didn't fit back on over the y-pipe. I gave him my old tunnel brace off a non-'vert.

That said, the header install was the easiest I've done, the y-pipe clearance was PHENOMENAL, and the merge collector in the Y was nicely done preventing rasp and drone. Also the header flange was nice and sealed very well against the head.

I'd recommend one of these to anyone who isn't a 'vert or wanting larger pipes and on a budget. If you're a vert...just buy the headers and build your own y.

 

Passenger side was equally easy. I did have to raise the car a few more inches but once high enough it sliped right up. I had to break for family time and dinner. I still have the y pipe to bolt up and switch the 02 sensor harness wires areound at the PCM. I plan to use the rear 02 harness to power the front 02 sensors

 

Finished up the header/y-pipe install. Ran into a snag though at the end. The outlet to the BBK Y-pipe is the exact same size as the inlet to my SLP catback. I had a suspision this might be a issue. So tommorow I am going to take part of the SLP catback to the exhaust shop and have the end expanded. I plan on getting rid of it down the road, but was going to run it for a while.

 

So I am just about to order headers and am deciding to go with BBK. Ive heard nothing but good things about them and the price can't be beat. I have one question though. In every picture ive seen of them (on summit racing, and even bbk's website) I do not see o2 bungs in the headers. I see places in the Y pipe but none in the headers themselves. I am wondering if the pictures just aren't accurate and they really have 02 hookups in the headers or if you hook them up in the y pipe.

 

I have been running mine since March and they still show no signs of turning blew so still to this day very happy with them.

 

There are 02 bungs in the collectors of the headers. Also there is a second set in the y-pipe for a wideband or whatnot. You will need to cap them if you are not using them. I found two short oil drain plugs from Advance. 18MM is what you need.

 

Do you have lm1? If so I guess im going to run into the same problem when I go to install mine?

 

I'd like to know what the size of Y-pipe outlet is, if you can let me know?


You got the coated ceramic or chrome?



So other that the tunnel brace on a vert issue which is trash from the get go and the Y pipe issue for a vert, thats it as far as negatives for a vert?? After market tunnel brace and perhaps an E cut out will solve those issues...

 

Mine are Chrome.

 

Would LOVE to see pics, if you had the choice over would you do chrome again or coated? I know the chromes costs less, I'm on the fence too...

 

Ill try to snap some tomorrow unless someone else has some to share if not ill get some.

 

I got the Chrome as well, the chrome finish was not great on them, but hey, what do you expect for 360$.

Yes I have the LM1. The outlet of the y is 3" about the same as the inlet that slides over the originalal y pipe. I was on Advance auto parts site and the store near me supposedly has a 3" band style clamp I may try before I go getting anything expanded. My GT500 has those style clamps on the exhaust throughout and they work well.

 

Hmmmm yea i may try and get that when I install mine let me know how it goes.

 

This is a shoot of my chrome headers after they have been in my car for almost 2 years.
