Another thing that you should look at this exhaust system is whether it has the lambda sesnor holes along the header pipes and post cat location. Some of the newer engines has 3 cats, 2 along the banana header, and one in the mid pipe, if this exhaust system doesn't have such cats and lambda sensors positions, your standard ECU is going to detect a cat failure, set itself in safe mode ( fuel rich mixture mode), and you will loss BHP.
If I were you, I would check the manufacture site carefully, if it mentions words like "track only" or "aftermarket ECU" then it is 99% likely to cause cat failure. You will need to install O2 cheater to the system, but O2 cheater is illegal in Europe. |
