After my right cat got clotted up, I put test pipes on my car..

So far, I've had no CEL, the car has about 15% better fuel economy, and the car accelerates onto the freeway better as well as accelerating from 60-80mph a lot faster. I didn't notice the difference until I put the LLTEK intake on, the car is NOT any louder, in fact, it might be a little quieter.

I'd say between the intake and less-restrictive exhaust, I have about 10-15whp.

I have the 2.8l V6

 

Hi ... I'm interested in doing the same - cutting out the cats. What did you do with the sensor?

 

So far I am dealing with the CEL, tomorrow I'll shim them.. I have had no time to work on the car

 

Can you explain the "test pipes" setup please? sounds like something i would like to/need to do to my 2.8.
