Took my lad's zed in yesterday (60k miles 2005 2.5) for a spot of work; vanos seals and secondary cat removal.

Wow! Yes, do it. :D :D
Certainly got more get up and go now. Sounds like it too - not surprising to look at how much a restriction each cat is on exhaust flow.

Think I need to get mine done too - just wish my facelift had secondary cats to delete!

Ooh, I wonder if wifey would like that on hers.
Just to confirm, what effect is the secondary cat deletion likely to have on MOT emissions?

Apparently none but I dont believe that, why would it be there if it didnt have any effect whatsoever :rofl:
It at least probably isnt enough to cause an issue with the MOT but thats 3rd hand info :idunno:

I used to do the secondary cat removal on my TVR Chimaeras
The sound is great and they used to feel as they flowed a lot easier
No issues on mot as 1st set still in

Has it made a noticeable difference then? :)
I'm guessing it's a tad louder too
