I have just had a chat with FR & R Tuning and they have recommend the THS one, he said its the same quality as the Miltek and comes with the adapters to fit the OEM centre section.  £145 inc VAT & delivered. Seems good.

Did you buy the THS part then, if so whats it like?

Yes, It's been on for a few weeks.

I noticed that the car seems to pull a little harder and feels a little smoother so overall I am very happy.

On idle it makes a funny wispy noise and you can also hear the turbo spooling when moving in traffic etc, sounds a bit like a police siren. Also sounds a little bit meatier when putting your foot down but not a hugh difference.

My mechanic made some modifications when fitting it so that I would easily be able to fit my old cat back on if needs be (MOT rules might change).

The risk of failing an MOT due to the confusion which seems to be prevalant puts me off putting one on right now.

I chucked a decat pipe on the misses's tdi 140 altea yesterday that I got off here.  Noticeable improvement. Revs and boosts smoother and seems to hold slightly higher boost at 4k.  Nice and easy to fit too.

It's not a ths pipe, but I would have got the ths version if this one hadn't come up cheap on here.

Is the Altea mapped? Do you foresee any issue with a Revo mapped car?
