De-cat

[ReNWiLL]

A lil advice please fellas. Not wanting to go mad on the addon front of my Williams, I was wondering.

All I have so far is a piper-x filter element, would putting a de-cat pipe on my Williams make much difference ?. I would be using the standard exhaust.

I have heard so many different views, some people saying upto 35% of power is lost through a cat, others saying it will degrade the performance as the back pressure would not be the same !?!?!?!?.

Opinions here please....Thanx guys and girls.

Well on every Williams and 16v that I know of, decatting it has always reaped benefits. Ive not heard of a single driver who would want their cat back on again after ditching it. Just dont expect a lot. It may feel a little bit more eager and it helps everything along but you wont see mega power gains. A couple of brake if youre lucky, mainly at the top end, but it all helps doesnt it!

Ive heard it gives 6 to 7 bhp more. Seems to have made a difference on mine. Although thats just my opinion. It pops in 1st nice too

My Williams has got decat, magnex system and K&N induction, and it got 163bhp at a rolling road day in May
