RoW Exhaust - aftermarket system position of cats

[Ranfurly66]

Hi

Thanks. I'm working my way through it just spoke to the workshop service guy and he's said it is an EU4 car (only 2 cats at the rear). It is a street car and I want to keep CEL light issues to a minimum/nil so I'd look to keep cats on the car.

So you're right. I have 2 options:
- full system headers with sport cats or possibly mid pipes with rear sport cats (trying to find out if the system I'm looking at has the O2 bungs on each side of the rear cat). It is the expensive option with possibly some HP gain, maybe, who knows.
- Just replace the rear muffler and have improved noise. The OEM system is so quiet! Quite a bit less $$$ to be spent.

My main issue with putting on sport cat headers is whether rerouting the O2 sensors from the rear to the front. Does that cause any dramas getting the O2 sensors forward - will they go that far?

Thanks
