    Had the Challenger Hellcat up on jackstands the other day installing the skip shift eliminator. After finishing the install, I decided to check the entire exhaust system for the leak that is marking up my floor. Really figured I would find a clamped joint leaking or a loose fit somewhere. What I found was a bad weld on the passenger side muffler at the inlet to the muffler. Let me be clear, I checked every joint and found no other blackened area on the entire exhaust system. I am fortunate enough to own a TIG welding rig, and repaired what looked like a machine weld by re-welding the area at the bottom of the pipe. I suspect that there was a run of machine welded mufflers that weren't set up correctly and didn't properly finish the weld overlap.:mad: It's been a week now, and I have not had any spotting of the concrete. I have started it up cold multiple times. Any muffler shop should be able to repair this if you find this is your problem as well. Hope this helps
    .
    BTW, The underside of this car is very well engineered. I was impressed with the number of heat shields, protective brackets, hangars, etc. Very nice.

    Now, on to the water dripping from the trunk lid issue.........:eek:

    Take the most powerful leaf blower you have and spray the back of the lifted trunk lid, sideways, up, down and all over, then place a towel btw the lid and the bumper overnight to rest and catch the rest of any drips. Right between that and trying to keep the engine bay perfect, it extends the wiping time. But, so worth it.

    I literally think they sat in a room designing this awesome trunk with a great design and made it the final product. Right as they were ready to show it off they remembered it needed to drain water so they just put gaps all over the place to suck up water and hold it and slowly drip it EVERY ******* WHERE

    Here is a repeat of my guaranteed trunk water removal procedure:

    Yes, I am an expert trunk flapper ;).. but it's more like 20 times in groups of 3 - 4 flaps, a few minutes apart. My guaranteed trunk water removal procedure:

    1. Wipe down the engine compartment
    2. flap, flap,flap
    3. Wipe down the door jams
    4. flap, flap, flap, flap
    5. Wipe down paint
    6. flap, flap, flap
    7. Wipe down windows
    8. FLAP, flap, flap (caps mean more forceful flapping...)
    9. Wipe down wheels
    10. FLAP, FLAP, FLAP, FLAP:mad::mad::mad: (put some english on it...)
    11. Drive it around the block in a "spirited" manner (helps to wring out that last bit....)
    12. FLAP,FLAP, flap....
    13. Wipe down rear bumper and good to go...:)
    14. Until the next morning.... wipe down the rear bumper again...

    They should add this handy instruction to the manual...

    Yes, I am bored this morning.... and yes, I said "flap"....

    ELECTRIC leaf blower. Don't use a gas one. They expel gas/oil out the blower.

    My driveway is on a slope. I wash my Cat as you se in my signature. All the water runs to the passenger side of the vehicle. Sure I have to flap the boot lid up and down for half an hour with a micro fibre towel laying under the lid but it works.

    Most cars I've seen pics it's the clamps up front. (There's even a fca tsb on it.) But there's also the weep holes in the resonators. Personally I'd rather let this leak sooner rather than downstream you want that for the longevity of the exhaust system.

    Mine was the weld right above the weep hole. Notice no black or soot around the weep hole. I had black/soot coming out of the bottom of the weld and you
    could clearly see the weld didn't overlap properly. Thought I might not be the only one.

    FYI...I have used my gas blower on everything from this cheap Challenger to expensive custom show bikes (several awards and magazines to my credit), never, ever have seen a drop or problem expelled on any paint or beautiful chrome.

    I was WONDERING what the hell is leaving those little black-ish drops all over my damn garage floor!!!

    I was worried it was something serious ; I'll have to have the car abuse people (dealership techs) take a look at this when I go in for an unscheduled test drive/burn-out (oil change).
