This ebay DP has a reducer to fit the OEM system... so youd need to remove that part of it so it fits with the 3" Milltek Catback

Excellent! Would i have a problem with an MOT with this fitted?

Post by: Scottymon on April 23, 2013, 02:21:26 pm: Down pipes aren't expensive... sport/racing cats are though.
If you buy the above you will essentially have a pre-cat delete and main cat de-cat and also increased the first section from the turbo to 3 inches from the 2.5 inch OEM.
You'd probably lose a little low down torque, but free up that brick wall of a pre-cat and bring down the EGT's and increase horsepower (with the right map of course).

That said, it seems a bit silly to buy this to mate it up to a 800 cell OEM cat though... I doubt there would be much in the way of gains from doing that and just doing a pre-cat delete and using the standard system...

Post by: mdmay on April 25, 2013, 09:02:37 pm: would this fit to my Octavia VRS. I know the engine and the turbo are the same but would this mate up with the standard exhaust system?
