Thanks guys, I'm gonna pass on removing the cats. I figured a 10 h.p. I probably would, dispite reinstalling them for aircare testing each year. But 2-3 h.p. I wouldnt bother.

Thanks again,

Emir


The turbo.
The turbo is acting as a muffler close to the source.

I have new cats on my car, hi-cap they are, and I have twin mufflers on my 3" custom exhaust system.

Like Loren says I don't tink you will have a increase sound if You remove the cats, but the stock ones create a preasure drop whitch creates a larger preasure on the exahust ports which consumes more energy from the engine to push the exahust gases out.
If You remove the cats You WILL get more torque but the question is how much?

When I replaced my entire exahust system (from header all the way back to the end pipes) I could feel a differance, well in sound also.

On the question if mufflers will be wear faster:
Yes probably they will wear faster, but how much faster? But how much faster?
Sorry I dont have info enough, but my guess is that You will not notice this.
