156 2.0ts DeCat

Hi Guys,

What is your experiences with putting on a decat pipe on these cars. What are the pro's and cons?

I would imagine I would have to keep the cat so it is available come MOT time.

CF2, no issues at all after removing the Cat, but yes you will need to refit for MOT.
Use stainless-steel M8 nuts & bolts.

Didnt think there would be. Will store the cat up until MOT time.

Can you guys notice the difference in performance?

Not sure... run on LPG so performance always feels great on petrol anyway.

Perhaps lost some low down torque and gained some at higher revs??? Thats sort of how it feels. Would need to dyno it to confirm this though.
