It'll also be nice to have the T5 with the 0.65 "transit" 5th.

Just make sure you have a high enough final drive to make it useable. 5th gear is useless in my car until I'm over 85. Below that I end up having to downshift on any kind of an uphill slope to hold 75ish. Of course, this is all estimating as I've never had a working speedo...

Well dotcha have like 3 of the Stup-rah diffs with 4.3 in 'em?

Ha! good stuff. At North Nevada Rally there were some long straight highway transits, and the 70mph nevada speed limit, the volvo has the 4 speed and the low rear end, pipe with one little glass pack and a resonator, it was screaming and not even breaking the limit! I like the sound, but its hard to hear the codriver. It'll also be nice to have the T5 with the 0.65 "transit" 5th.

You heard the co-driver just fine...that was the screaming... grinning smiley

I can put a nice exhaust on for you before Olympus if you get up here a day or two early. Something like this...

Yeah. 3. One needs rebuilt with probably a bad bearing.

Is it a pretty square beam? I'd love to have both in my car.

Do It Sidewayz
Please get Ryan @ TRF to tuck that cat up well, and put some shields around it.

there are 2 things in the world that kill cats.

#1. Heat....this is caused by running a car flat out for long periods of time...cats are designed to run at 20% throttle cruising down the highway. Run flat out they not only don't really work as cats, but they also over heat. The only solution is getting it further from the engine.

#2. Impacts....no matter if it's a metal core cat, or ceramic. The impacts even to the exterior surface will break apart the insides.

IMHO, there is ONLY one place for a cat in a rally car, and that is 3" from the exhaust tip at the back bumper.

I actually just finished a 2.5" system on a '98 civic with a JDM B18 in it. The system was a JDM brand header (greddy or something), with a glasspack resonator in the mid-pipe (basically in OEM position), and a Metal core cat at the rear bumper. The car is not terribly loud, he actually drove it to work a couple times already, and drives it to rally-x events.

I can tell you that on this civic, at the end of a good trackday run, look inside the tail pipe and the cat core is glowing RED!

Also...if you are using a ceramic cored cat, you will not get any more than 3-4 events out of it, so be prepared to change. Doesn't matter where the cat is (under car or in the bumper), or if the car is N/A or turboed.

If you use a Metal core cat, the cat will last longer than your car, assuming that you put it in the rear bumper.

Ideally, I wanted the cat in the back and have the v band clamp so I can disconnect it for Honda Challenge races (whenever I run one), but I also wanted a muffler. Couldn't fit both back there, at least by eyeballing it. I did get a metal core cat at least. But I am going there tomorrow to check things out. Maybe we can size up everything and find out that the cat will fit in the back with the muffler. There's really not a whole lot of room to work with back there.

/crosses fingers

The only other thing about cats is them clogging on transit driving. But then again, I'll be doing transits at 4500rpm anyway. So I'll probably get some heat back there for it to not be cold.
