WTF?? $2000 to replace cats? & update fr the shop

Are they both rattling? How badly.

In my case, there was a faint rattle on the left side. My indy looked at it and was guessing the cats. I went round and round thinking about what option to choose, OE or aftermarket, cost versus quality.

Then, to my surprise, I pulled the exhaust while I was rebuilding my shift linkage, and when I put it all back together again, the rattle was gone. That was over a year ago. Maybe give it a try. It's cheap compared to new OE cats, which is basically the only real option in terms of fit and quality. Nothing else sounds like a good option.

I talked to Mike Miller of Tech Talk in the Roundel, and with a guy I know at Korman, and they both had to admit that the OE cats are really the only way to go, they are just really pricey.

Best of luck,

R.

Sucks for you. :(

In the "States"... we have this legal ambiguity sometimes referred to has "clear as mud". There's usually a clever way to get around some red tape loophole with a splash of good old fashioned ingenuity. What our beaurocrats do is make laws with ultra high expectations, yet hire the most moronic dumb asses to enforce them. You see the advantage goes to the well informed... :D

Lucky bastid. :flipoff2:

We have the same car, I cant wait till mine looks more like yours. Sick ride dood. Vewy niiiiiiice.

I cant tell. Thats the thing. It's hard to re-create the rattle without a lift handy. I suppose I could floor jack her up on stand, cold in the moring, and have my wife in her nightie come out and fire her up with me belly to belly with the beast. :shrug:

I have to say though, now that I have about an hour on her out of the once over... the annoying rattle has all but gone away. By replacing some exhaust bracing, I believe the problem is still there, however the exhaust is not moving and vibrating as much, therefore the broken ceramic has less to do now.

What I'm thinking...

When needed, get the cheapest POS cat to pass the siniffer, get the job done. Good for two years, whoptie doo. Immediately toss the OEM's back on.

plan

As others have said, there are no good aftermarket direct fit replacements available. The DEC and A&B are worthless, with a max life of about two years. Most of the people I know who've installed these things say that they come back within a few months, and they tend not to pass HC emissions test to begin with.

The OEM cat isn't expensive when one considers that they last ten to fifteen years.

Personally, I'd weld in a carsound magnaflow and be done with it.

best, whit
