How do those compare to OEM cats in price?

Damn, I wish we could do that in this state. So, I am consoling myself with an order for a Remus custom exhaust today. A factory group buy has been set up JUST for the remanufacture of these for the W126, a one time deal only. You could get in on it too. www.Remusexhaustshop.com At least I will get 2hp, really good looks and a very nice sound for the money.

Magnaflows are around $110/ea. Random Tech about twice that.

I'll have to say again, not installing high flow cats is horribly short sided and irresponsible to boot. Why pump out an ungodly mess of polutants when for a about 200$ you could have made the car 50 state legal
 For anyone contemplating removing your cats I'll state again, you'll lost Less then peak HP...something you can't even FEEL... FYI, for the price of a Remus (nothing more then perforated core pipes surrounded by fiberglass) you can put up the Bulk of a full proper mandrel exhaust w/ high flow cats utilizing the Exact Same technology the Remus uses..all in stainless to boot.

(removed the resonators and tossed in a magnaflow muffler, spent $120) But if you got this kind of a difference by custom precat back... well i just may consider it, I can always have it welded back in later.

Well precats are known to be, from my experience, more restrictive than the main cat is why I asked. I could have sworn all the factory stuff on the Gassers was also basically straight through?

The OE cats in these are both of the honeycomb variety, ie quite restrictive. It would be one's best interest to R&R the OE cats w/ a high flow magnalow bits. You'll need one if you run the US manifolds, 2 if you have the euro bits.

I'm not a huge advocate of no cats either. Hell, there are 11 and 10 sec 1/4mi cars that are STOCK that are 50-state legal... and get 27-30mpg. If they can do that...
Most modern cats have shown less than 7rwhp to be gained after removal on mildly hopped up vehicles. That's within the realm of dyno error guys. If I can't find a set of the Euro TriY headers, I'm just going to toss on my base Euro dual manifolds and a dual in/dual out single Magnaflow cat on the 560. Has anyone dissected the stock 126 gas exhaust system? Didn't one cat say just the rear muffler gained ~2hp? I wonder what the resonator/center section is made from...

100lbs drop is usually worth about 0.1 in the 1/4mi.

They use a metal catalyst and are a small tubular straight thru construction. I'm running twin #59954 in a true 2" dual exhaust on my twin turbo M103-12V. Originally tried a SL500 style OEM cat, but the Magnaflow showed a 11HP increase on the Dyno over the single large OEM V8 cat !!!

. Much faster off the line and I can tell its running the way it should. I would recommend doing this if you are a real driver and would like to spend less on gas. It's a shame that this car came in the US with cats... Now it feels... right. the Sensor was $150 CDN and the custom exhaust a whole $200 ooohh $200. Do it, this Xmas give the gift that says "I love you" and have the Cat removed.
