I to have had same problems developed mine at 500 miles in. Basic reason to me (advise it’s taken to dealer at time it happens) most twin exhaust systems have two continuous pipes running from engine (separately) to the back of the car. For some reason two pipes run from engine, then join into one large pipe until it hits the rear exhaust box, so all the exhaust pressures, meet at one point in the rear muffler before being expelled out the attractive but useless twin exhausts.

same here... noticed it long ago but wasn't sure if it's just carbon build-up in the exhaust...
yup the perpendicular style of the exhaust make's it possible for this discoloration ![]() now i'm thinking of having an aftermarket exhaust or have them just painted with high temp paint. ![]() .....up in the tree!!! |

It sounds simply like some heat discolouration, and the only reason I would be worried is if it is visible when looking at the rear of the car, other than that it sounds pretty normal.

You asked for it.... Maybe you should wipe it! Have you tried some Vaseline or KY? That should stop the heat build up! ![]() |

Maybe its Thrush, Canesten cream is apparantly good for this. Npinks we are happy to help you on all your issues as you are amongst friends but do not try to disguise them as vehicular ones....just be honest |

Carl I believe it's an i6 only problem, due to the twin exhaust. |
