De-Cat Driving Differences

[Arr0nUK]

Had a search not realy found what im looking for.

Basicly whats the differences in driving with a de-cat fitted on a 182.

for example is it more responsive at low revs, does it use more fuel, ext... stuff like that.

Hope you can help thanks

In general, better response, improved fuel consumption on normal driving, improved lower torque & upper Rpm power

Just makes the car nicer to drive daily, There are better gains on the 172 than the 182 but over all both see benefits

Yup, recently put my cat back on, instantly notice the difference. Pants!

would a decate sounds pants on a standard 172 exhaust system? or wont u be able to tell?

 

[oinotna2008]

the car is more expensive about fuel consumption?

Improved fuel consumption?

 

[mattjk]

In theory it should improve very mildly

 

[Ben..]

is this the same for a non sport?

How about reality?

Yes, I noticed this too! On a drive in 5th gear at 60 I'm getting nearly 5mpg better! Just got mine done and driving back from town I got 48mpg 5th gear at 50 for ten miles!

That's awesome lol!

Wont make a difference lol

 

[DannyR]

Wont make a difference lol

Your wrong there, Torque on the car is so much different, feels a lot easier to breath and pulls a lot harder lower down

Brilliant thread! I just fitted the cat back RS197 exhaust system, sounds great, feels better too. And i was wondering the exact same!

So think once MOT is done, de-cat here we come!

Thanks for your opinions!

greater lower down torque! less noticable 5k kick smoother power delivery! am i right in thinking that the improved fuel consumption comes after you have had it remapped?? if not then i have something wrong haha!

 

[Mark One]

decats do make a difference. And fuel consumption improves.

Mines not been mapped for it yet and its vastly improved!

I'm talking about fuel consumption if you read the quotes properly please

 

[Luke.]

my fuel consumption went from 30mpg down to 26mpg but i dunno if thats cus im holding the gears more because its more noisy eeeeek! got 36mpg on a run doing 80mph

If you get a decat do you have to put it on again for MOT or will it pass regardless?

It will pass with the right tester

Enjoyed mine, but wasn't willing to take the risk with insurance, so it came off. Regardless of the benefits, the insurance issues make it a no-no for me.

Exactly my thought, insurance is void as the car is not classed as road legal.

Surely if your car has valid MOT then it is road legal?

As far as im aware, cars with M.O.T + de-cat, either know a M.O.T tester who put's his emmisions tester on another car, or they take the de-cat off for the M.O.T and then back on after. (this is what my mate does in his supra)

But i wasn't aware until reading this last night, that it void the insurance, (suppose if i thought about it more instead of getting excited about the good responses i may of realised).

I'm now not sure what to do, think ill play with air filters etc, see how it improves the sound, and go from there.
