    Knocking sound 3" downpipe

    Just finished up bolting up my 3" relentless downpipe, and now all of sudden a annoying knocking sound has appeared when I take off/ accelerate / full lock etc.

    I checked cv joints are okay, checked sub frame bolts and engine mounts...all good :/

    Any suggestions guys?

    I'd guess the DP is hitting something when the engine is rocking under acceleration/braking.
