IS200 Decat Manifold
IS200 Decat Manifold
Mine also goes straight through the MOT with no pre-cats.
One of the reasons a few of us with the chargers remove them, is because they break down and clog the exhaust? not sure if its the extra heat that does it? but a couple of guys have had them collapse after fitting the supercharger?
From just decatting the existing pipe, VERY slight according to my exhaust guy. Mostly just extra noise.
However a properly tuned manifold like the TDI Katana ones that use to be available might give you 10hp increase if your lucky.
right i have in my shed a tdi katana!
it wont give you 10hp i had a cat back that and a camcon and made 165hp on dyno std it was 153hp
does sound nice tho
