One of the most restrictive things about your existing exhaust is the fact that the pipe differs in diameter through the mid section where the catalytic converter and valve are located. Many think that removing the cat by means of breaking it out is sufficient, this is not true.
Our modification removes the complete section marked by the red lines and replaces it with a careful matched straight through section that allows the gas to flow through without having to deal with changed in diameter. This is then neatly welded again using tig. You can expect a 6-7 horsepower increase with the correct map fitted. The Lambda sensor will remain in place
