I took my exhausts off to fix some stuff on them, can't get the things back onto the manifold cleanly. The flange is about an inch away from the thing I'm mounting it to right now. The bolts feel really tight, should I just keep tightening it down? I'm worried about breaking something. Is there some trick to making this work right?

Bolts to long? See how much higher they need to go and take the exhaust down and try the bolts themselves.

Didn't these have studs in them? I've always heard using bolts isn't a good idea as they will seize in the manifold and twist off when you need to remove them again.

Crazy as it seems I checked the factory drawings a majority of them did specify bolts instead of studs

Makes a lot of sense thanks, any recommendations for studs to get? Don’t reckon my local autozone will have them?

Didn’t make it out today, but aren’t those to attach the manifold to the engine? I’m looking to attach the pipes to the manifold.

The ones in the link are pipe flanges to manifold. That's a generic kit though that contain 2 different lengths. Looks like you'd have to buy 2 kits. Do you have 2 on each side? If so, maybe you can find another kit or buy 4 individual ones.
Check your other local parts stores too.

Yep, I used this same kit when I put my new Pypes exhaust system on a few months ago. Works great! Mine had bolts from the factory, and they came out very easily. Guess I got lucky.

Probably any decent auto parts store-NAPA, for one, should carry these. 3/8 NC Grade 5 or better, I actually like Murdoch’s, if you have one nearby. You can buy grade 5 or grade 8 bolts by the pound.
