i got the donut gasket off, and today i'm going to buy different longer bolts that aren't spring loaded to close the gap. locking nuts and big washers as well.
and, of course, put a hanger on there.

when i installed my RB catback, i just went ahead and bought a new donut gasket. the old one was stuck on there pretty good... so i took a dremel and cut a notch in it, then used a flat head screwdriver to pry it apart which made it come off real easy. then i installed the new gasket. a tip i learned was when tightening these types of gaskets.... tighten them like they were your wheel... dont crank one all the way down then go to the second... tighten the fist one a bit, then tighten the second one a bit, then go back to the first and keep doing that until they are both tight, youl see this will help keep it all aligned as well....

Just use the donut gasket and all will be good. I'm been running a RP Supercat with no hanger for a good 30k miles now. The main difference on why it will work without a hanger is the weight difference between the stock cat and your midpipe.
You may want to get some high temp neverseize and coat the mating surface of the donut gasket so you can easily take it off next time.

i tried it with the donut gasket and the spring loaded bolts, and it still leaked just the same. this is just a temporary fix until i get a catback in a week or two when my bonus gets here.

even that way, there's still a 1/4" gap.
we're not talking about something not sealing right, we're talking about something that's so off that it doesn't compress on one side at all.
do i need to draw you guys another picture on autocad? lol.

(when this is all said and done in a few weeks, it's going to be a true 3" single exit all the way back, no cat, just 2 big resonators in the midpipe.)

well, i tried my method of buying different bolts, and it fixed about 80% of the leak. now it's just leaking out the top. it doesn't even leak after it gets warm now.
Lord ET, I didn't think of that. i'm going to give that a try here in a little while and see how it works.

you need that support--rmember that header doesnt have the support that the oem manifold has(the bolt on thingy). if you are using some other type of support for the header make sure all of that is loose when you begin to tighten. the cat back maybe off a little also. it should have some flexibility to mate up with the midpipe. get those soft aluminum gaskets man, if there is an 1/8 gap those type gaskets will take care of it--np.

you can stick your hand up in there (your GLOVED hand) and feel the exhaust pulsating out. i know exactly where it is... that's not a problem. i'm just going to have to wait until i get a catback that'll mate up better than the stock exhaust does. no biggie. i'll probably order it next week. that rx7store midpipe is just too short... bottom line.

I'm looking for info on the exhaust flange bolt, which I'm having trouble getting it back on. and this thread is the closest I can find.
The Spring loaded bolt and nut I'm having problem with unscrewed at the midpipe, rather than the nut itself, not really sure how to say it. The bolt came off with the nut still stuck to it. So, I'm having problem putting it back on since the spring has to be compressed so much that it will reach the midpipe hole. Am I making any sense?
Anyways I tried everything to get the nut off the bolt but its impossible. Since theres no place to clamp on the bolt, and it took a breaker bar to get the other one loose.
Is there like a mini spring compressor somewhere for this, I cant seem to find the right name for it to buy one.
Thanks

hmmm... have you tried emptying a whole can of liquid wrench in there? Also, if the nut came off, you should just be able to hit the spring part with a mallet. If that doesnt work, heat it up with a torch (or get a shop to do it) and replace the spring bolts. Charles from BHR can hook you up with new ones as he includes them with his midpipe.

Thanks for the info, I did use liquid wrench but the bolt itself is small and there isnt a good spot to grab it by to break the nut off. I'm currently trying to compress the spring with zip ties so the bolt can reach the threaded hole on the midpipe. If all goes bad I'll just get new ones.
