T bolt which slides into frame notch.

BOSTONCAMARO

I used dental floss to hold bolt in place, problem is the bolt needs to be pushed back so that the sidepipe can slide by, due to the mounting tabs. I ended up using wire on the rear bolt and also reaching up into the frame after with a long screw driver to push the bolt through once the tabs were lined up. I slide the sidepipe on all the way and basically let the header line up where it wanted the sidepipe to sit as I didnt want to preload or torque the header. I still need to trim the rocker moulding but setting them in place quick, looks like will be a great fit. I also took off the rear wheel to allow the sidepipe to slide in easier, as you have to slide it on from the rear, I hit the tire.

All in place, easy to get it with open end wrench.

Rear mounting tab, I snipped off the blue wire after.

Moulding that needs to be trimmed.

Another shot.

Passenger side T bolt tab, there was a big flap covering it that I snipped off, I did smooth it out after, made it look good

Header went right in, without jacking up car and without taking starter out

Measured to get idea how far the sidepipe is on, it will not go on the full 3 1/4 inch that the header seems to allow. Probably in about 2 1/2 inches.

Had to round the head of the allen bolt on the second bolt back on the number 2 cylinder, it simply would not clear the header tube, I also shortened it a couple threads so it would pass through and also slightly chamfered the hole. Was quick, easy work and not near as bad as stuff I have done for other header installs for other cars.

BOSTONCAMARO

Here is the chamfered hole, which I also finish sanded after, it allows the bolt to pop right through.

I could have shortened another allen wrench but simply used some good small channel locks to tighten this bolt...it is tight, tight like a tiger. I did also have to very slightly, barely touch two other bolt holes to allow the bolts to pass through easy, went fast with an air dremel.

In place and done!

Good job. Nice install. Looks good.

As we discussed, the header bolts may be the hardest part of the install. Especially the one in your pic. The problem is the tube overhangs over the hole in the flange. Impossible to angle in the bolt.

Like you, I tightened up 1" bolts for the other holes. This allowed me to use a shorter .75" bolt for that one difficult hole. I then grinded the thread end of the .75" bolt just a little bit more. I was then able to angle in the bolt without altering the flange. The key is to use the small head header bolts.

thanks for the compliment, yeah for this one bolt hole I should have used a small head stainless ARP header bolt, but this is what I had on hand, so my quick mod worked out fine. I will say they fit and look great, if anyone is considering sidepipes, these seem to be a great way to go

Camaro...

I totally agree with your recommendation for OBX pipes. I've been saying that for months with a mixed response. Much of that was from those same "Made in the USA" vs. "Chinese junk" posters including most who don't even ride with sidepipes. These OBX fit and look great. All for $600. That is hard to beat. It took your excellent post with pictures to prove it. Nice job.
