sports CATS

Post by wrekka » Sun Mar 20, 2011 6:33 pm

I'm not willing to pay £1200 - £1400 for new 100 cell sports CATs, so just wondering how much realistically should I be looking to pay for a second hand set of 100 cell or 200 cell sports CATs, or even no CATs at all? Obviously I know that a re-map will be needed too whichever type.
cheers

Contact your local Milltek dealer and ask them for the test pipe for this car. Not too expensive but you'd definately need a remap.

As reference I paid £650 for a set of barely used Miltek Sports Cats. Which is about the going rate and a fair price.

600-800 sounds about right, depending on mileage.

An alternative/cheaper route would be to get precats removed (gutting) by mrc . Ofcourse u will be left with the 400cell oem cats but that might not be a bad thing. I wil stil have good back pressure and majority of power gains come from removing the restrictive precats rather than from reducing the 400cell to 200 or 100...........I think...

hi folks,

sorry bout the slow response. Test pipe is essentially a full replacement pipe for the length where your cat is. This method is better if you intend to decat as you can still keep the original cat at home in the event that you need it in the future. The test pipe comes with all the necessary clamps and also sensor mount points. You'd definately need a remap for this though.

A few questions:

1. How much HP gain
2. Can i run it with the stock exhaust?
3. Does it make it much louder?

Lookin for HP gain, but not louder.

Thats a no-cat downpipe your talking about then?? There approx £500 from milltek plus fitting,they are expensive considering they have no slinncers or cats,but they do have the flexi joint in there to stop you shearing off your manifolds or exhaust when the engine moves under load etc.The more you open up the cats the louder they will get,gutting pre cats will give some gains but not ideal to leave a hollow tin shape it surely cant be good for flow,milltek 100s or 200s are fit and forget and will pass mot no probs with gains of 10ish bhp unmapped perhaps and another 10 or so when properly mapped by mrc,the car will throw codes anyway if you dont map it and run crap when cold,no cats is ultimate performance but mot pain in the arse

I had 100cel cats and downpipe from Milltek fitted after I had a non res Milltek. Believe you me its significantly louder than just a non res cat back. On the day I had the cats fitted one of the B5 owners that had heard it testing at MRC before I arrived reckoned it sounded like a Lamborghini. It just sounds ferral, also throttle blipped downshifts give a Group B rally car style bang out of the exhaust which is always useful for emptying trees of birds or indeed having lots of people jump/crouch in more urban settings.
