TC22RE

So I'm having a thought here. I'm running a turbo'd 22re in my '94 pickup with a custom exhaust. As of now the exhaust just has a muffler in it (no cat), I can't even remember what kind of muffler I put in there. Now my thought here is, remove the muffler, and in its place put in a catalytic converter. I was thinking it may up my exhaust noise some, and with all of the gas this thing eats it will probably help out the environment a bit (Plus we may be getting emission checks here soon.) What do you all think about this route? If you suggest putting a cat in do you know of any reputable aftermarket high flow cat. suppliers? Thanks in advance!

i think there is a reason for having both - that would be annoyingly loud -

I do applaud you for taking the initiative to put a cat back on it

To be honest, I'm not really concerned with the noise. I ran this thing pouring exhaust out of the turbo downpipe for about a month, I figure if I can stand that I can still stand having a full exhaust system w/o a muffler. I was thinking the turbo + cat combo will dampen the noise enough so as not to be too ungodly loud. I'm actually looking to pick up a decibel or two.

It's fine. I ran a cat with no muffer for quite a while and it's really quiet on a turbo.

Guys without a turbo - the turbo creates more backpressure than your stock muffler, it's really a big mufller.

I've got an SRT-4 and it came factory w/o mufflers... The only time you'd need them is to pass visual inspection (in some areas).

Location of that converter is critical though...

magnaflow makes a nice cat.

Thanks for the input! As far as the cat location goes, I have no real experience with cat. converters but I imagine they probably work best the closer you can get them to your manifold/header. Of course you probably don't want them too close. So I'm just guessing. What do you say?

I would get as close to the original cat. position of 22rte as I could, or (correct me if I'm wrong) any 22r/22re engine.

Well, my muffler is about a foot behind the stock cat location right now. See any problems putting the cat in its place? Ittle be a bit further downstream, but like i said, only about a foot.
