vdubfamily 0 Posted April 17, 2009 Report Share Posted April 17, 2009 Hello fellow dubbers,Im having a little issue with my mk3 golf vr6. ive just had a bunch of work one on it but still more problems. I just installed a new 6-2-1 branch stainless manifold and a stainless scorpion cat back exhaust. I just found out that the exhaust is overheating and has burnt the abs wiring on the back chassis. Anyone know what might cause the exhaust to overheat like this? cheers.Down and out bruthers....the only way Link to post Share on other sites

vdubfamily 0 Posted April 17, 2009 Author Report Share Posted April 17, 2009 its possible...how can i check those? Link to post Share on other sites
sirleeofroy 0 Posted April 17, 2009 Report Share Posted April 17, 2009 well the fuel mixture would come up on vagcom and would prob have something to do with the lambda sensor as thats happened to mine..Btw, did you check your cat when doing the exhaust? Link to post Share on other sites
rodney 17 Posted April 18, 2009 Report Share Posted April 18, 2009 is the car FI? Is the exhaust glowing anywhere or just blummin hot? Link to post Share on other sites
DAZVR6 0 Posted April 20, 2009 Report Share Posted April 20, 2009 Probably the 6 branch needs wrapping... Link to post Share on other sites
vdubfamily 0 Posted April 20, 2009 Author Report Share Posted April 20, 2009 everything is just bloomin hot. the exhaust and cat are roasting the underseal. I now got grey dust sittin on the end of the one tail pipe and black dust on the other. Link to post Share on other sites
VR6Pete 1,455 Posted April 20, 2009 Report Share Posted April 20, 2009 your 6 branch will need heat wrapping. sounds like there could be a blockage somewhere? could it be your CAT is collapsing.I'm assuming you havent removed the heat shields that normally sit between the zaust and chassis ?
