spudley1988 Posted October 1, 2015 Share Posted October 1, 2015 Hey folks, got stainless manifold decat and mongoose system but the tinny rasp noise is disgusting. I know hondas can rasp but heard so many others that sound nowhere near mine and now had a few honda chaps aknowledge the tinny noise. Cant be picked up much from video but its much worse in person and giving ful chat. Now id believe lack of resonation but likely to be from centre box or rear box? Sadly only have video of old system which was another mongoose but rasp heard in the video is much much worse. Quote Link to comment Share on other sites More sharing options...

spudley1988 Posted October 1, 2015 Author Share Posted October 1, 2015 Mine was raspy even with standard manifold just got bit louder or worse with aftermarket one. If I tap throttle to make it pop almost sounds mega tinny like one of the boxes or both are empty but could be wrong. I'd be happy with similar to the deck in video to where mine is now. Even in car the tinny rasp is borderline cringe Quote Link to comment Share on other sites More sharing options...
spudley1988 Posted October 2, 2015 Author Share Posted October 2, 2015 Yours a box or a can Tom? Think may need to bite the bullet and buy a system. Surely lack of baffles has to be the answer lol Quote Link to comment Share on other sites More sharing options...
Krzys Posted October 2, 2015 Share Posted October 2, 2015 My EK Spoon cat-back became very raspy when the baffles exited the system Quote Link to comment Share on other sites More sharing options...
spudley1988 Posted October 2, 2015 Author Share Posted October 2, 2015 Any sound clips of your box....... Quote Link to comment Share on other sites More sharing options...
spudley1988 Posted October 2, 2015 Author Share Posted October 2, 2015 First video sounded as if it could have been raspy but possibly just the echo cause second video and the tip one didn't either. Something definitely wrong with mine sounds a lot raspier than that even from inside Quote Link to comment Share on other sites More sharing options...
