Got my janspeed decat fitted at local exhaust place, what an affort we had to fit it but its on now. It has made the car slightly quicker at high revs so im happy with it that way. The problem is that when accelerating hard in first and second the engine is moving so much on its mounts that the flange where the decat connects to the manifold is tapping on a crossmember or sub frame and causing a quite annoying knocking. I took it back in to tell them and we messed about a bit tryin to sort it but to be honest there is know way of getting anymore clearance so im a bit stuck with it. Has anyone come across this or any ideas on things i could try at the moment im living with it but only just. cheers

engine movement shouldnt really be affected by the de-cat i would have thought its more likely that its been incorrectly fitted somehow and there is less clearence hence the knocking that you didnt previously experience. my de-cat hasnt suffered these problems so can only guess its either the fit of the pipe itself being poor or the place that fitted it have done a poor job of lining it up
It took about an hour to fit id say but that was at an exhaust place with me helping. Thats the only mod at the moment and i can genuinely say it has made it slightly faster especially from above 100 just seems to rev that bit better top end. Yer both sensors are pluged in and no lights yet. Ive done about 300 miles this last week and the vibration seems to be going away. Not sure if thats a good or bad thing!
It was making a vibration when the engine was moving on its mounts the decat flange where it connects to manifold was touching subframe, when accelerating hard in first second. It has stopped now but from nothing i have done maybe badly fitted or what eva was vibrating has dropped off but its not doing it anymore.. And yes i still have standard system..
