The Exhaust Question That Has Not Been Asked

well.... I have been searching and can't find a viable answer anywhere.


please pardon my ignorance in regards to the mechanical aspects of the automotive world.


ok, here goes: Every car manufacturer, Exhaust, and custom shop always exits the exhaust at the back of the car underneath the bumper.

What if I wanted to make my exhaust Non visible and terminate it under the vehicle - with a downward angled tip of course. I like the stealthiness of it, and if you don't get on the gas, people really can't tell what you have ''under the hood'' or that you even have an exhaust/performance modification.
This would also keep the back of the car a LOT cleaner in terms of looks.

What are the downfalls of doing this vs the old standard? I mean, in my day of performance trucks and muscle cars, guys terminated the exhaust in front of the rear tires...
So whats the difference? If any?

Re: The Exhaust Question That Has Not Been Asked

Look closely at a current model VW Golf TDi, they don't have a visible exit for the exhaust - the tailpipe dumps just short of rear bumper area.

The disadvantage of this is the possibility of the waste gases staying in the area under the rear bumper, then of course the possibility of spark + waste exhaust gas could = explosion. Though I think this possibility is low considering that the engine should've already burned all the combustibles in the gas.

Over here you'd get in trouble since the legislation clearly states that the exhaust must exit the bodywork, but I"m not sure over your corner of the world.

Alternatively you could have it finish up near the rear bumper and have all the pipework and muffler painted flat black to make it harder to see.

Re: The Exhaust Question That Has Not Been Asked

i dont think its a good idea

first of all the bottom of your car would get pretty ****ted up, more so than normal at least

secondly, if there are any areas that leak into the cockpit, such as worn gaskets around the shifter, the exhaust is going to get inside the car. this is why exhaust leaks under the car are supposed to be fixed.

lastly people will see the exhaust pouring out from under your car and think you are too lazy to fix it

Re: The Exhaust Question That Has Not Been Asked

i think in ths case you should customize it from the header to the back of the front tires.. that way it doesnt stay under the chassis

Re: The Exhaust Question That Has Not Been Asked

Wow... I appreciate all the feedback.

I am getting ready to replace my exhaust system and this thought came to mind... while I did consider the possibility of an ''air'' leak, I am sealing EVERYTHING up and replacing all the rubber gaskets so that wouldnt be so much an issue. My goal is to be quiet, the whole build of my car is focused more on the sound system and creating the most opportune environment I can. Speed isn't so much a desire for me.

Re: The Exhaust Question That Has Not Been Asked

in essence the closer the exit of the exhaust is to the motor the louder it will be, because of the velocity of the gases. but if you could tuck a cat, resonator, and muffler up in there somehow i doubt it would be loud at all. just gotta make sure ur gettin the right stuff.

Re: The Exhaust Question That Has Not Been Asked

You need to take the safety precautions and put a heat protective guard for the underside of the gas tank. I have this exact setup. However, do not cheap out and buy some junk resonators. You will regret it. I bought a nice resonator and it sounds good yet I have an equal length manifold which really helps the sound tremendously. Also running a high flow cat and not some crap test pipe. I love the look of it as I hate how the exhaust sticks out the back. I don't have a problem with the cabin noise since it is essentially a racecar so that is something you need to consider as well

Re: The Exhaust Question That Has Not Been Asked

thank you!

Very informative! I didnt even think about the heat issue at the fuel tank.
