This question does not pertain to daily drivers. Think of your weekend car or track car when answering the poll
Fender/bumper or out back for me.
I think both fender and hood exhausts are copouts for fabricating a complete exhaust, unless there is no way to make it fit or your car is built for maximum lightness, the weight savings will be marginal.
Hood exhaust is lazy ricer shit.
On a track car I’m ruling out side exit (at least before the rear tire) because why would you want exhaust temp air right ahead of your rear brakes? I have no idea if the physics would back up this concern though.
I missed the behind the rear tire side exhaust exit on my Expedition every time I went to hook up a trailer on the Murano or now with the CX-9. With the Expedition it was no problem to leave it running while you were hooking up a trailer but with the other two while you’re standing there usually one leg is being toasted by hot exhaust gasses.
It depends on how nice the weekend / track car is. Let’s say if it’s under $10k then do whatever you like. If it’s worth more than that then maybe consider full exhaust.
my touareg TDI was horrible for this. the exhaust would blow on the chains and not only make everything hot but cover the chains and everything in soot.
I think it depends. I’ve seen some really awesome side exit exhausts, but I probably only thought it was cool because of the car it was on.
I’m a hood exit fan but it really depends on what car it’s going on. I’m assuming this is a turbo application?
Hood exit with smoke stack.
I have a side exit on my truck, dual rear on the car.
road course setup i would do a pass side right before the rear tire- offsets some of the driver weight and wont echo off the wall on the drivers side right next to your head (like the roush did lol).
drag car, i would do out either fender before the front tire- which side based on how the turbo was laid out.
Don’t do a hood exit. It will leave carbon on the windshield and ruin your field of view. I used to have a WG dump out the hood and after a hard night of running it, I would have a carbon streak up the windshield. If this was a drag car and made only a couple passes then yea oh well do what you want.
If this is N/A put a full exhaust on… You do not want a headache racing this thing whatever it may be and you also want to Match up the exhaust Pulse to your engine for your desired RPM you will be running at for a better torque curve.
yes turbo, because no exhaust would fit any other way
Option 5, Roof:
Picture of the “Fender exist exhaust” anyone?
Click on this link, it has some images.
too many variables to answer this.
the vehicle and its application would change where I would have the exhaust terminate.
If you plan on doing some sort of sanctioned racing I would check the rules for that first.
I had wastegates that exited out of the hood and it would fog up my wiindshield at night doing a wot pull
i think that the coolness of anything but a full exhaust wears of rather quick. I’m glad I have a full exhaust and dumptubes exiting under the car now.
That still doesn’t show me the fender exist exhaust.
No, that link does show that in fact fender exhaust do exist.
