just fit a 3 inch catless downpipe ( swapped from a 2.5 sports cat)

now when i drive the car I can feel the car rumble far far far more in the cab - is this usual

bit worried the downpipes bangging against the centre tunnel its that bad

 

i have also moved back from Equal length headers to un equal length but still tubular

 

freezing fingers - the downpipe was banging on the side - temp fix now

thanks
