156 JTS 2.0 exhaust upgrade
I'm looking at upgrading the exhaust and airbox on my 2005 jts 2.0, its a 5 speed manual. I have been looking at de-cat systems as I had a coil drop out on me and now i get an engine warning that the cats are faulty (they copped a bit of raw fuel), so far it's going to work out cheaper ( plus better performance) to replace the cats with a de-cat system.
has anyone done this before ?? and what else needs to be done to make this work properly..?? I've noticed there are sensors before and after the cats, do i need to do anything to these..??
I'm also thinking if the exhaust gets an upgrade I should modify the airbox as well...what would the best option for this be..??
thanks in advance for any advice
