Hi this is full system with high flow sports cats fitted by Tony Banks in Leeds. They fitted 90 degree spacers for the rear o2 sensors and the car didn’t like it. It wasn’t getting any reading from the sensors and the car thought it wasn’t getting enough fuel. It started running rich as it was over fuelling to try and compensate. I went back and had the spacers removed and it was all fine. It did however through a code for post cat efficiency as the sensors were now getting a high reading. I had these mapped out when I had the car remapped and it was spot on after that. Personally if I was to do it all again I wouldn’t bother with the sports cats. They didn’t really improve performance and all they did was mess up the fuelling and throw an engine management light. Just go for a cat back and leave the cats alone I reckon
I put usp high flow cats and a full cat back exhaust. It didn't like it either because it just ran rich and killed my power, but a tune it gained a good 22 whp over stock with the much better free breathing exhaust. Lesson learned just get a good tune and you are set.
Oh lawd
Good sound!! Whats your exhaust configuration??
Miguel López longlife stainless with hi flow stainless sports cats. Stock air filter, no induction
Can you go into a little more detail who made this exhaust? Is this a cat back or just flow cats with stock muffler?
