Buschur Down Pipe
Hey guys I have a quick question.
I bought this down pipe used a few days ago. Didn't come with hardware or anything, just tr DP it self. I reused my test pipe gasket and bolts, that was fine, I also got bolts for the hangers and that was fine. But my question is, should I use a gasket from the 02 housing to the down pipe? I had to remove the stock doughnut gasket and now I'm gasketless lol. Also, I reused te stock spring bolts, is that correct? I got them pretty tight but there's still play in the springs. Thanks in advance!

Doughnut gasket doesn't fit. I also did a quick search before installing. Doughnut gasket removes easily and is replacable.

I have a spare 3" gasket but I dot want to use it yet until I find out if I need different bolts for the DP to the 02 housing. Those spring bolts don't seem like they're connecting the two pipes together very snug and I'm almost sure I can hear a leak. And like I said before I torqued them down very tight but the springs on the bolts are still loose.

The spring bolts are too long. I found out that you can order up a set of these http://www.streettunedmotorsports.co...turbo_bolt.htm and they work great. Good luck

I called Buschur this morning and Nick answered. To say the least, his costumer service was unsatisfactory. I hung up feeling empty. He pretty much told me that they sell the hardware kit for $49! Talk about swindled. I asked for te thread pitch and he said he can't remember it off the top of his head. That's fine I understand that. But he was rushing me off the phone. So now I have to wait for the weekend, take the bolts off and have them fitted at a hardware store. Thanks for all those who tried helping. Ill post thread pitch later for reference

Yea, the buschur dp doesnt use the stock donut gasket. It just uses a standard two bolt gasket. Actually, you dont need a gasket really. I use the copper high temp gasket maker for my downpipe to o2 housing. Never had any problem with leaks, never used a gasket there. Then just grab you some bolts. I wanna say they are m8x1.25, but im not 100% on that.

You are correct sir, thank you again. For Buschur down pipe to stock 02 housing, unused a M10-1.25 and it was 40mm in length. Also added a washer. About to test drive it but the bolts gave it a good bond compared to the stock spring bolts.
Edit: you are semi correct. Not M8 but M10 is the size. I think the 1.25 is the diameter no? If then, then yes you are correct. I'm not so good with bolt sizes.

Buschur downpipe doesn't use a gasket which is pretty stupid if you ask me, I've searched and found plenty of people with leaks. I had a leak as well which threw my wideband off at idle. I found this gasket that somebody on the forums was using and it works perfectly, it's a round crush seal gasket for a catalytic converter on a mazda, havn't had a leak since.
