Should I de-cat my rica'd t5 s70?

[tomtyres]

Hi every1!

my s70 feels quick to me, it did a 14.5 at santa pod too, but i want MOOOAAARRRRRR!

it has a 'longlife' stainless cat-back system.

my mate can de-cat it for me easily, but i dont know if being rica'd, will ££££ it all up?

will it benefit the performance?

any help will be happily recieved!

cheers, Tom. :)

I'v never NOT known a difference when going in a car thats had a de-cat.
On a turbo you want it as freeflowing as possible, the cat (expecially the standard one) is quite restrictive.
