is there a dummies' guide to exhaust upgrades on here?

My GS is a January 2005 so very early... It has 4 lamba sensors. I guess the decat will be a bit tricky. Would a pair of 200 sports cats allow the car to pass MOT on emissions and be able to fit between the header and the squish pipe? Even the larini option for my car retains the 4 cats.

Hi Alex , there are a couple of ways round it that David at Larini will be happy to explain , im pretty sure they can link the two rear Lamda's into the sports cats if necessary , i would definately go to remove the quish pipe it makes so much more free flow ,and with the centre H section it would sound excellent , It would raise the the growl to a howl when the valves are open (if your keeping the standard rear boxes) with popping and cracking on de-throttle , i have some picks of mine on the Larini exhaust thread . Larini valved rear boxes are just the icing on the cake and tone it that bit higher
