De Cat benefits / gains?!

[artur69uk]

I have been looking to de cat my 172 mk2 phase one for a while and just wonder if it will be worth it power gain wise. Also How much louder does it get!

Cheers

Bit louder and pops, that's it. Oh and the lovely smell of raw fuel

 

[lewba]

mmmm i like the raw fuel! das prob y i work on an oil refinery hahahaha

 

[Dan Page]

yeah the smells ace lol

deffinately has made a noticable difference on my 182 and doesn't really make it much louder imo. it is deffinately louder but not too bad at all really....

Throttle responds quicker, stronger pull through entire rev range, deeper burble on full chat (no chavvy sound), occasional popping on overrun, a little less mpg, a b**ch to change at MOT time (172 manifold), quick to change at MOT tim (182 manifold).

I have no problems with MOT my car is registered in the Channel Island and there is not MOT there lol

I might get it de cat but put a extra silencer because its quite loud as it is!

Agree other than most of the ppl on here will back me up, its better on mpg with a decat, not worse!!!

Yep, very slight but better mpg.

Cheers guy looks like Im going to get it de cat on saturday! Will let you know how it goes, is there anything that I need to make sure gets done like the the sensor does it need to be welded in again or can I just remove it?

 

[many lemons]

def. get the de-cat i had mine done and the car feels mucher better now and the sound is good:lolup:

if you take it to a decent company they should automatically fit an new lambda sensor, they done mine, there is one either end of the cat, so make sure they are aware of this. and i agree with the rest sounds awesome! not loud at all, just sounds alot healthier and more powerful, and it certainly does increase throttle response, similar rip to that of the v6

 

[Fred@BTM]

fit a new lambda sensor???? do you know how much they cost!!!

you only have to remove one of them and then put it into the decat pipe

good to hear this , ive just ordered a 4-branch manifold for mine and wasnt sure to go with a de-cat because ive heard it slows it down .

gains on my 172 were
1,7 KS on the wheels without remap ( without cat )
6,8 KS on the wheels with remap ( without cat )

That sounds like a good gain!

When I was motorway commuting, I was getting 42-46mpg with my decat on. No worries there, mine's probably a hollow pipe by now anyway lol.
