Decat on standard system, YES/NO? Why?

[lambrosj]

So.....

Car is currently getting a bit spoilt and now in the capable hands of Tom & James at JMS, having its overdue Cam & Aux Belt change including few other bits

Anyways booked into a custom exhaust fabricator on Saturday to have a blow sorted on my car, its blowing from the O-Ring between the Cat and Downpipe so went to renault bought gasket etc and gonna have it fitted on Saturday.

My exhaust fabricator said he would do me a deal on a De-Cat pipe to mate to the standard system, now is this reccomended?

What are the advantages and disadvantages I should expect?

Is it worth it? (standard system)

WIll it be too loud?

Will it kill my MPG?

Now before you all tell me the le/m lights gonna go on and I cant pass an MOT etc etc, I already know this and am prepared, mate Hussain at the local Norf Londan MOT station (Joke) will pass it and I can live with E/M light on.... Ha Ha Ha

Any input appreciated,

Thanks Chaps!

I would go for a decat only if the cat is broken and I can't afford a sports cat.
With the standard exhaust it shouldn't become too loud. Car should rev more freely above 4-5k and lose a bit of torque low down.
Obviously you will get that old fashion smell of fuel!
I think the engine will sound a bit rough.

Gardus thanks for that mate,

Thats what I was worried about was it sounding rough, I mean considering my cat at th moment is not great...... :clown: I think maybe the de-cat route is the way to go, dont mind the fuel smeall and loss of slight torque and the car really does seem a little strangled at higher RPM so should be good to have the mod!

I Just wouldnt sacrifice the noise I currently enjoy for anything other than an improvement...... Argghh decisions...!

Doesn't make a different really...Minimal noise different and no more power, also the risk of damaging the back boxes.

get a 182 cat fabricated to your car that will be far better and not silly loud

then get a decent stainless cat back system, it will save you money in the long run when the standard one disintegrates

My standard exhaust with decat sounded no different

My standard system on the Cup with decat does sound different, not massively but it does.
