Decat for mk1 172(2000)

[Aids172]

I am thinking of getting a decat but am concerned about the management light coming on. Will it definately come on and does it cause any problems with the car?
How do they sound as the last one I had on my 106gti I took off as it was so raspy and spoilt the exhaust note?

Just removed a Janspeed decat from my mk1 172, sounded great and performance to match. Only removed it for the mot. Not putting it back on as I will be selling the car very soon, so I'll sell it to you if you like? The engine management light didn't come on with me.

how much you wanting for it dude?

there are 2 different types of exhaust in the Mk1 172's.

Mine (march 2001) has 2 lambda sensors, one before and one after the cat... so a decat on mine will make the light come on.

Some earlier 172s only had 1 lambda sensor, making them easier to decat

 

[GarethM]

like mine only one sensor

Are they really loud and raspy? I already have a k-tec stealth system !

 

[GarethM]

it wont be too loud on the stealth system but will get louder than without it.
doubt it'll be raspy!!
