Re: Cat suggestions please

If you have to pass for cheap, get a cheap one. If you've got extra cash to throw at it, get one of the high flow units. Magnaflow, or something like that. We don't have emissions in MI... yet.

Re: Cat suggestions please

If you go for a HIGH FLOW cat will you experience boost spikes? I heard to stay with a stock STAINLESS cat when I get my SS 3" exhaust, is that what you would do ?! ---

I got a 3" stainless Magnaflow from a list member for $60 but there are universal cats on ebay all the time for $35.

Just get a 3" universal off ebay and have a local shop fab it in for ya.

Mine is high flow, but if you're running a stock chip and stock turbo you may want to stick with a stock replacment to avoid boost spikes.

my bad.

Hey, Missouri just passed new legislation to revamp our emissions program.

We are getting rid of the loaded dynomometer sniffer and going to strictly OBD2 scans.

What that means to me:
1995 and older no longer has to pass emissions starting Sept 07.
Vortec heads and open DP here I come. :tup:

I you want to pull a fast one you could do what I did. When I ripped out my old cat when I went to the 3" ss exst. I cut the stock converter in half (ban saw) then hollowed it out drilled 4 holes and clamped it over the 3"pipe with a big hacking gap showing. The inspection shop laughed so hard they gave me a 9.3 for creativity. In reality they are not required to check and see if there is a functioning cat there just as long as one is there.

LOL, I have the same laws in NY for older cars, when I had my camaro, I had a shop cut them off for me( cause they didnt want to get in trouble) I took them home, gutted them, then bought them back to the shop, and they welded them back on. :D I stopped blowing collector gaskets after that. O, and when I didnt have a cat on my ty with the stock turbo, it was spiking like crazy, over 20lbs. Good luck!! :tup:
