Exhaust tips getting HOT!!!?
 

Hey guys,

I just installed the AAM Resonated Short Tails (only mod)...I was grabbing my bag out of the trunk the other day after driving and my leg hit the tip and gave me a quick burn! I was really shocked how hot the tips were. Hot enough that you could only quickly tap them with your hand for a second or so. I don't know if the tips on the stock muffler got this hot as I never checked. Definitely don't want them distorting the paint/plastic on the bumper long term. What do you guys think? Should they be getting this hot? I doubt this could be anything to do with the way the car is running because its such a small mod that the ECU would adjust to. Would hate to see the bumper discolored or burnt like one of those ricer civics...

Thoughts? :ugh2:

Absolutely normal. And it won't affect your bumper at all, the only time discoloration occurs on your bumper is generally from cars with catalytic converter deletes.

I've never heard of an exhaust getting hot, make sure your muffler bearings aren't seizing.

I've had to replace my muffler bearings 3 times already. COME'ON Nissan!!!

I only have 1,500 miles on the car...Highly doubt that it the issue...Putting the stock HKS back on for comparison..i will report back shortly

Maybe. But you never know???

True...Just put on the HKS for comparison and the tips get just as hot..Looks like ill be replacing my muffler bearings and blinker fluid next weekend! :eekdance:

Blinker fluid at only 1500 miles? I'd check the gasket or spill-over valve. It shouldn't be leaking. :hello:

Y'all are crazy�� the stock tips will probably run a little cooler as the muffler gives the gases more time to cool, but it's nothing out of the ordinary.

Please keep the mechanical jokes or none helpful replies to the FB page.

This is the tech section and a member is simply asking for basic help. :ugh2:


Op

There's nothing wrong with your tips as long as the tips are not contacting the bumper it'll be fine.

Keep your lower body away from the exhaust tips as they maybe hot enough to burn especially when the weather gets warmer.

Do we really need to warn people of the obvious? :rolleyes:


And another thing "THERE ARE NO SUCH THINGS AS MUFFLER BEARINGS!!" :bowrofl:

Or blinker fluid.

Please tell me this is a joke lol...in all seriousness the exhaust gets hot...extremely hot. My buddy burned the crap out of his leg on his R1. It shouldn't cause melting nor discoloration but try and be careful man...

You guys should try getting out of a side piped Viper after doing 30 minutes on the track without getting your legs scorched.:eek:

If you are replacing your muffler bearings too often. Try adjusting your flux capacitor by using the anti-ricer flyby screws. ;)

What's all this about exhaust tips getting hot? I have ART pipes, Garageline X and Mid-pipe combo, coupled with the stock HKS Nismo exhaust. Mine only are warm after driving, such that I have no concerns with pulling my car cover over them immediately after parking the car.

This is exactly why I posted about this in the first place....obviously I know exhaust headers and cats get extremely hot but I was not sure about the end of the system. Mine are getting really hot as stated above. Wasn’t sure if it was how the exhaust was flowing with the AAM Resonated Shorttails I just installed or the lack of insulation in those tips compared to stock. I did put the stock HKS on yesterday and they got equally as hot. Your the second person to tell me that your tips are only getting warm not hot.

Mine get hot too. I have the full FI exhaust. I wouldn't worry about it to much unless you are burning something under the car.

Even before I did the cat delete and X and Mid-pipe, my exhaust tips still were just warm...as a way of comparison. From the responses here in this thread, it's apparent that there are two very different experiences with the temps of this car. Interesting...

I see how many people would think this is a dumb question, but based on the different responses it is becoming quite interesting. My buddy has an infrared temp gun..I'm gonna hit the tips with it later and see what they register at after a long drive. I cant imagine they are over 200F...

W......T......F......

:facepalm:

FP,

Really though...look at the different responses I'm getting. Some say theirs are warm after long drives. Mine is nearly scolding hot after mild driving. I think its a totally legit question. I don't wanna melt/distort the bumper and paint. I also saw some posts that people said car exhausts get extremely hot when the car is running lean...so again I think this is a totally legit question. :stirthepot:

Koz, I think you should specify just how hot the tip is. Get an infrared temp gun, then you can really test the temp @ different section of the exhaust. This will help legitimize or dispel your concern.

Exactly what I am doing tonight. Will let you guys know.

Yeah because what's hot to you might not be hot to a blue collar guy like me lol!

Took the readings tonight after a light 20 minute drive, ambient temps about 60F. Tips read over 200F...it varied due to the reflection but anywhere from 190-220F. The inside of the resonated short tail was reading about 250F..Good thing is the bumper above the tips was luke warm. Also took a reading on a 2004 Santa Fe and the muffler tip was 250F. I wanna say that it’s normal...but have not a clue how some people are telling me their tips are getting just warm. Very interesting

Maybe our OEM exhausts, have these "fake tips" that make the opening bigger than they actually are, like a funnel. The "tip" that's exposed therefore is not as hot when compared to aftermarket ones. Maybe, maybe.

They'd be warm in winter at -30°C.

So final thoughts before we lay this to rest..200F+ normal for tips? Should they be so hot you can only tap them with your hand. This is more a matter of making sure the car is running right (i.e. not lean).

Some of it depends on the design of the tip. Some are insulated, some have vents in them.

:iagree: My HKS does the same thing though, and they appear to be insulated.

Metal transfers heat.

These cars are smart and will generally determine a lean/rich problem pretty quickly and compensate as such. Usually throwing a CEL. The high compression of the VQ would definitely emmit extreme heat... I think these warm/hot arguements are subjective without everyone having a real temperature reading. Still can't believe this is even still being discussed lol

3 pages so far... love it!!
