just wondering guys but what sort of performance gain would you get from just having a De-Cat pipe put in with a standard back box on a 1.8 astra.

Any ideas ?
 
It's actually not anywhere near as much as you would hope - probably only 3-4 bhp max which is about the same as filling up with low quality super unleaded instead of standard unleaded or going from a bad condition dirty plugs and fitler to having a fresh major service. It would also mean an MOT failure. Wait till the cat dies and then replace it with a High Flow Sports cat.

I think the closed loop system will also throw a wobbly if the cat were removed - I'm trying to remember where the probe is in these exhausts.
 
cheers waynne, i was just wondering really cuz i found a de-cat pipe for 98 quid on a side and the pipe seemed to go from the manifold down and all the way back to the back box, i think that site did sports cats as well i'll see wether i can find it again
