I'm not trying to be fancy here. The Monroe shop that did the exhaust on my '95 940 for the previous owner did a hideous job. Apart from welding the cat to the front muffler (at a weird angle, no less), and leaving off the center muffler hanger, I've just discovered they used a cat intended for a Turbo car (which this car is not). They chopped a couple of inches from the slip joint on the muffler, and maybe the end of the cat. Then butt welded the two (badly), as the diameters are the same. I realized the cat was the wrong diameter, and too long for the car while trying to install a new Starla system.

So I can buy a new correct cat, but would have to wait, pay money, wait, and waste a low milage part. Did I mention I'll have to wait. Other option is that I can shorten the turbo cat by cutting between the cat and the three bolt flange (there's four or more inches there, unlike any other aftermarket cat I've seen). I can then weld a length of the correct diameter pipe (2 1/8"?) to the other end, and slip my new system on. I could have the car back on the road tomorrow. Shortening my brand new exhaust is not a desirable option for me. I'd rather pay and wait.

So that's the back story. My question is, am I losing torque by having this slightly larger diameter catalytic converter on my car? It basically has no power until you hit about 3k, but I figured that's normal for an N/A wagon. But if I'm losing even a smidgen of power, I'll pay and wait to get the correct part on there.

Thanks for bearing with my long winded diatribe.
