But it will make it v. Loud if you have a aftermarket back box. My de cat put around 10 bhp on my set up so can't see how they lower the power 2bf lol Last edited by spike_202 on Sun Mar 20, 2011 7:44 pm; edited 1 time in total

read his project lol
hes got a s**t load more air going in than anyone else so a decat is guaranteed to help flow in that situation.
cant see the benefit on a standard engine though without serious intake mods..

Cut cat out, weld pipe in. Well I think it something like that anyway!
Exactly, pretty hard how to do a how as you have to know what you are doing. Or if you have a decat pipe ready to go on you could fit that. But it's a b*****d fitting into the centre pipe, as well as removing the old one + getting it to fit without gas leakage.
I have a de cat purely because my cat compltely broke and rattled with a fair while till the MOT and it was a lot cheaper / easier to fit and weld a pipe on and just fit a second hand cat for the MOT then change back again.
what did it sound like when you de-catted it?
It's deeper and a fair bit louder, I have a peco backbox and it was loud before, and now it's annoying loud. Also backfires quite a lot but it didn't with the standard backbox so it's probably a mix of the two.

She is quiet and gains are good, compared to standard
But when you are concerned about back pressure, gimme a break its frigging 1.4

Slip the MOT guy a tenner and im sure he will wheel in a nice 1.0 corsa for your emmisions tests

Would have to be a total idiot to risk his mot license like that
People say it so casually, but I would feel like a knob trying that...
Because you are one.....
Love you lots
Oi you

I don't know how I would go around finding a garage to 'pass' it for me.
Do I already have to have exsisting friends?
If so, I'm f****d..
#30: Re: de-cat. Author: Lewis1304, Location: NuneatonPosted: Mon Mar 21, 2011 4:09 pm ---- Friends who work for garages yes or ask people who are in tuning car circles where to take it locally. I just take it same place my mates take their evo and ST's etc.
