Ok my rear box is blowing because the n/s hanger pulled away from the box and the mot station did a pi%$ poor job of welding it back on(although they were kind enough not to charge for it as it blows now...)
so im in the market for a cat back system,have decided on eismann or supersprint but my query is regarding the cat i had a look and making a pipe to replace it isnt an issue should be easy to pipe bend a section however i then noticed it has a pre and post lambda sensor will removing the cat have any adverse effects on the cars fueling or power etc or is it a better idea to source a sports cat replacement??? or any other options i havent considered?
any input would be appreciated
Btw as far as mot's go my uncle said as long as i have my cat with me in the boot he will pass it.So mot isnt an issue its purely a will it run right and is there gains to be had from cat removal?2lambdas?
