Hello,once again i have a small problem with my car it has very small miifire,today i took it to the auto mechanic.He was checking the fuel distributor,he was pushing it too uch the car was going like crazy,but it was gasping for air sometimes.He went to the back of the car and checked the exhaust,and he realized that i have one side of the exhaust was completely blocked and the other one was filled with the isolater of the inner exhaust.So he told me that we have to change THE STUPID UNIVERSAL EXHAUST cos it is cosing a block and maybe i have distroied the catalizer.
Is it possible that this caused the misefire????
Do i have to put a new cat.converter or can i put only normal pipe,which is 1 million time cheeper????And what the difference will be?:thumbsup:

Not sure what the Plzen version exhaust is like ;-) but the US version has two pipes coming out of the rear muffler but really only has one coming out of the muffler behind the cats. So what really is wrong with your car - it doesn't sound like you really could have a "one side blocked" exhaust from what you describe (unless your car has a very different exhaust than a US spec car)
