It's a straight replacement decat pipe. No internals, has the flexi section and threaded boss for the lambda sensor. Not sure if he is making anymore though. From what I heard the PTP one is cheaper now.

so its pretty much the same as a janspeed or does that internals. i like the idea of having a lambda sensor. no mil kit needed then? but wouldnt that set the light off if janspeed manifolds were fitted as there will be no pre cat and then that picking up high emmisions?

If you go the Janspeed manifold route you will need a sports cat and possibly the MIL kit.

Question for those that have Janspeed manis: what do you do with the pre-cat lambda sensors? Are these still fitted to the downpipes via bosses?

The decat has the lambda boss as you still need to screw this into the system, the OE manifolds pre-cats do enough to get it through the emissions, the post cat sensor is redundant.

Yes they do Mike.

I had a reel of thermotec and gave it away doh!


I had my decat fitted this morning..........................woa! Superb :D

It's like I have a new toy to play with! Sounds awesome and compliments my Janspeed system!
