I am considering getting the Invidia midpipe/downpipe for my 06 IS250 RWD found here: https://h-tune.co.uk/invidia-exhaust-mid-pipe-70mm-lexus-is250-350-06-13/

Can anyone clarify, does this have zero catalytic converters and one resonator? Also, would I fail my UK MOT emissions with this installed?

I'm a noob on this stuff so any advice is greatly appreciated.

 

Yup, no SECONDARY cats. You’ll still have The primary catalytic converter’s that are on the lower part of the exhaust manifolds.I am on sure about the European emissions.

 

Thanks for the info. Hopefully the primary cats are sufficient to pass emissions tests.

The same item at RR racing mentions it has high flow cats which is why I'm confused: https://www.rr-racing.com/Invidia-IS...hs06lismip.htm

 

Megan will retain the cats.

 

Megan midpipes have three resonators (one large and two small) and zero cats (unless there's a variation of the Megan midpipes that I'm not familiar with).
