2 or 3 parts exhaust system in B230F (Volvo 740) ??

Question

Hey!I'll change the all exhaust system in my Volvo 740.I've got B230F motor with catalisator and lambda sond (the lambda is install before the catalisator,..is install near the engine, in collector). In this moment the catalisator is put out because it's damaged,..so I've got two another silencer.I don't want buy the new catalisator. (I use the LPG Patrol for my car, so I don't need the cat.!)I want to buy all new exhaust system to my car,..but I think, if  I can buy 3 silencers system (from models without catalisator) or I must buy 2 silencers (the system from models with catalistor and 2 silencers)??What are positives and negatives for install the 3 silencers system (from car without cat.) to my Volvo 740 (primary with catalisator,but now only with 2 silencers)??

You can safely leave out the catalyser as it is not necessary on your car and your Lambda probe is installed upstream of the cat where the manifold becomes one pipe. It is possible as a temporary remedy to rod out the catalyser (carefully remove all elements from inside the catalyser so that it is just an empty box), or to replace it with a piece of pipe of the correct size.

All the best, Peter.

Yes, I know it,..I've installed the pipe in catalistaor's place. But I've to change all my exhaust system,because it's very old. And I don't know what buy?? Only 2 silencers (I've got 2 in this moment) or buy 3 silencers system (from models without catalisator). With 3 silencers will be more silence than with 2 silencers?? My engine will work good with 3 silencers?? What with engine's power and sound of my engine in 2 or 3 silencers system??
