Hi there. I'm new to this forum, and just purchased a 2016 F-Type R with only 2,638 miles. Found it in Florida, posted a deposit, flew there the next day, drove it, had it shipped to Reno. Just returned from a thrilling drive up Pacific Coast Highway from Hearst Castle to Carmel with two tight mountain passes across the Sierra Nevada mountain range going and coming home. Love this car! Looking for any information anyone can provide on one exhaust pipe (not both) leaking condensation from the flange. The soot is ruining my colorful (and expensive) driveway pavers. The dealer says "it's normal, from weep holes, designed that way." I wonder why not both pipes then? Others on this forum say it is a poor weld and should be fixed. Any knowledgeable certified Jaguar mechanics out there who care to comment? Is there a weep hole right at the flange (just behind the rear axle, before the muffler)? Is this car designed to stain my driveway?
Anyway, happy to be here. Recently sold a 638hp ZR1, but I really think this car is more fun to drive!
IMO you could probably tighten the clamps holding the pipes as shown mid-way through that discussion. (Might be easier than driving it back to the selling dealer...)

While blocking the vacuum lines to the exhaust gates I noticed the same sort of seepage that the OP is describing. Even though there had never been any stains on my garage floor I thought I'd see if the flange was loose so I gave the clamp a good "two grunts and a fart" and nothing budged. I decided to stop before something was stressed to breaking.
It is normal, there are slots in the bottom and this is the low spot in the exhaust where condesation would collect and eventually rust out the stainless pipes. All exhaust systems/mufflers have weep holes in them for this purpose.

Maybe they cut costs by going miserly on the chromium content.

I used to believe stainless steel couldn't rust until I realised there are a vast array of different stainless steels for different applications and have varying resistance to acidic liquids at different temperatures amongst other factors

Come on
Lance, you live in Maryland where there are harsh winters and salted roads. stainless rust that is used on exhaust systems. I don't know what the alloy, but they're rust RESISTANT, not rust proof! I can always tell northern market cars that come to Texas by all the rust underneath and on the exhaust system. I have even replaced 2 of the rear mufflers used on the xk and Ftypes for rust holes and leaking. Yeah they don't rust like plain coated steel but they can and do still rust. Try being under a hot 1 and have that hot water drip out o the weep holes down your back

I have had this problem on two of my other cars. The cars leave their marks!! Ive got black dots all over my floor. I I tried tightening clamps. No luck. I modified the clamps to get betting circumferential grip but still. Drips. I just ignore it now. I dont care anymore
I concur the the joint just behind the rear axle is DESIGNED to relieve condensation. But if it is too much then perhaps it should be tightened or the clamp replaced. V8 exhaust joint behind rear diff, looking forward
Our V6 is just slightly dirtier than the one above. I don't have drips on our garage floor but I don't let the car idle for long, before driving away.
no at a couple points in the middle. And checking the mufflers with a magnet it has a strong pull so a lot more ferous steel content than the pipes which probobly eplains it.

OK...I understand now. I don't even consider the 409 alloy to be stainless. That will draw a magnet and rust. 304 has almost twice the chromium content and 316 even more. My VAP muffler is 304 stainless and is still shiny after a year and 8k miles despite the Maryland salt.

Lance if you look at Paul59 pic above. Follow the soot marks back inline from the inlet pipes and the rust through on the mufflers I have replaced in the past are right inline and at the low point. Rusted out from within. Small holes though nothing large. And easy to spot because they then let the watery soot drain out there too and you could easily see it.

I’m just disappointed that Jag cheaped out with the 409 alloy.
409 alloy will last a long time (which is why many carmakers use it these days for exhausts). Isn't the requirement 100k miles?
@Brutal are you saying that the muffler pictured has rusted out? To me it looks as if the drip got 'tracked' rearward onto the pipes & silencer...
Oh well, that is why we try to drive our cars 45 minutes at a time....
no not that muffler pictured,. Was refferring to the couple i have replaced under warranty and unhinged wanted to know where they rusted through. Worth mentioning is i knew both owners worked close to home and they were low mileage and short trips will never heat up exhaust enough to vaporize the condensation in humid texas. Hell i run a dehumidifier in my shop at home 24/7

Exhaust Pipe leaking condensation and soot
