Dennis the meance Posted December 16, 2016 Share Posted December 16, 2016 I've got system with no boxes from cat back and it sounds quite good for a 1.8tdci Quote Link to comment Share on other sites More sharing options...
gavingilmour Posted December 17, 2016 Author Share Posted December 17, 2016 Mine sounds pathetic and considering I've done the same as other people but mine sounds worse it baffles me and no one seems to have an answer lol Quote Link to comment Share on other sites More sharing options...
m1tch Posted December 19, 2016 Share Posted December 19, 2016 Debackboxing a diesel, in terms of sound and performance the car is still quite quiet due to being muffled with the turbo and the fact its compression ignition rather than spark ignition, performance is slightly improved due to the better flow meaning spool up is better, the MOT however will flag it as part of the exhaust system missing - have had this issue on 2 of my diesel cars.
