Well, after making the mistake of not lubing up my new TOB in my new clutch kit from a couple months ago, the TOB is already making noise slightly... I'm dropping the tranny this weekend to knock it out, but I'd really like to avoid exhaust leaks like i got last time I dropped my tranny/exhaust. I've heard you can rub RTV where the pipes meet, but I was wondering if there were any good techniques I could use?

Do the pipes not fit together correctly?


I suppose if you had to, u could put some copper rtv on the joints. But if everything is straight and tight, there shouldnt be any leaks.

Well last time I dropped the exhaust, it was the stock h-pipe/stock catback. Now, I'm running a newly added BBK o/r x-pipe, so hopefully it should be an easy fix.

get teh pipe snug, then manhandle it a round so it will seat for the msot prat. snug it down then start the car and get things to heat up a bit (about a minute or so) then hit the bolts with an impact wrench... this usually works for me...

Don't be a doof like I was the first time I went to connect my X-pipe to my headers. I slid the collars up and cranked them down and proceeded to crush the header cone. I didn't have the cup properly oriented and ended up with a horrid exhaust leak. To fix the problem I had to replace my headers with new ones.

Slowly work the bolts up and wiggle the X-pipe around to make sure the cup and cone are properly seated - especially if the X-pipe was installed before. I wouldn't waste my time with the silicone as that just burns off anyway.

Sounds good, guys. I'll be doing the job next Wednesday, and I plan on making a few changes since last time I dropped my tranny to do my clutch. I figured it'd be a great idea to get a case of beer for the night. Ended up with a loose tranny mount, exhaust leak from passenger header, no reverse lights, and a ****ty job on the throwout bearing obviously!

I agree, don't bother with RTV since it will burn off, if not immediately, within a few hundred miles I guarantee. As described above, you have to wiggle, tighten, wiggle tighten to make sure everything is seated right. If it still leaks (like mine did) I don't know. I wish there was a flexible asbestos collector gasket out there we could use, but I have never found one.

You're a freaking God. How many will I need, one for each pipe connection? So four?

Does that gasket come back to a Nissan? Is that correct?

Thank RIO5.0, not me. he told me about these gaskets. he had the same problem and he uses them all the time. just like i do now

just get one for whatever connection was leaking. its a 2 bolt exhaust gasket so just cut it so the outside is round. i put a thin coat of copper RTV on the ball and socket and slid one in. leak free.

not sure what application its for. just go down to your parts store and tell them them you need a exhaust gasket, Walker part number 31540.

Thanks a whole lot. I'll be picking these up before Wednesday, when I'm doing the TOB.
