Thread: Guys with front exiting exhaust. I need your input please.

Tweet

Any of you who has front exiting exhaust, whether it is going out and back, before the firewall, under a front fender, how do you like it? Does it get annoying? I'm thinking of dumping my exhaust in the middle area of the back of my front fender. I'm just worried it might get old on a long trip. What do you guys that have yours set up like this think?

Mine exits just behind the firewall, right at the door edge pointing down at maybe a 30 degree angle or so and angled out maybe 20 degrees. It's baffled,but is still a pretty loud rumble at cruise, and loud to the point of wondering about needing hearing protection if you're into it all the way. Ask 34_40 and john boy, as both of them have ridden in it for highway stretches plus some cruising in traffic. I'm to the point that I'm thinking about alternatives for a possible future modification, but I really like the look, which one of my boys says is "the defining visual feature of the car". I think you'll be happier if you take the pipes out the back, over the long run.

Roger, thanks for the input. I think I can get it out the back, but that's still up in the air. I've always loved the look of a slammed pro street willys coupe with a blower sticking out of the hood and the exhaust coming out from the fender. I'll have to see what room I have when there's a body and engine back in it.

I would think that fenderwell headers, pointing down at the ground will give you a considerable amount of resonance with the sound bouncing up and hitting the floor on the highway, but I could be wrong. I recall driving my old '60 Chevy with a 348 and new glasspacks ending right below the front seats. I was about deaf from the drone after 100 miles....

If I go out the fender, I am thinking a single pipe at a 35* angle back and up similar to zoomies but with only one maybe 3" diameter pipe. I agree headers and turn downs even with a short muffler will make it annoying and hot probably too.

I'd have to agree with Roger, especially on a sedan which will most likely haul your family around on occasion. I'd definitely find a way to take the exhaust out the back even if you have some kind of dumps up front for racing & playing around. I know with my 66 shortbed F100, for a short period of time I ran with the exhaust turned down just before the rear axle until I had time to finish running it out the back. There was a huge difference of loudness in the cab even with 50series Flowmasters. I love great exhaust sounds but I don't have any interest in losing my hearing or yelling at my passengers to have a conversation.....

This is an exaggeration as far as the car, but that is the look I kind of had in mind as for the exhaust out the fender. This will be a last resort though.

I've worked on and driven some 63-72 Vettes with nasty BBC's and side pipes, and that is something you don't want to drive on a long haul without a good set of ear plugs. I was guessing it may not be a whole lot different 3-4 feet farther forward.

At 3 or 4 feet further forward, I would imagine the noise into the car would be worse!

True. I have a couple of friends that have headers with baffles that dump at the lower cowl area. One car is straight back, and one is down. They both claim they're so nice to drive. I think they're full of it just due to the nature of them.

Ryan I’m planning on running the exhaust on the 37 out behind the front tire and out the back. I picked up a pair of these from Jegs a while back. I’m too cheap for the high dollar electric ones and they are a lot more compact anyway.



I actually plan on having header flange on the end of the pipe that exits behind the tire so I can physically cap it off (like the old exhaust dumps we ran back in the 60s) but that will be primarily for looks . I love the sound of the old HEMI thru the headers but not sure I’d want to go any distance with it that way.

I've got 2-1/2" pipes coming out just ahead of my back tires. They sound great outside the car . . . not so much when driving for any distance. Next move - out the back.

My 69 nomad, in front of rear tires. It's muffled down pretty good, but exhaust comes in under some conditions. Probably bad seals around the tail gate.

Ryan, I have removed a few exhaust systems that dump in front of the rear tires because of discomfort on trips. Even with mine out the back, I have a couple of the Greybeard friends that have complained about my car setting up a drone in theirs when they follow on the interstate. Inside for us, the hot rod exhaust effect is there (sure ain't no silent German luxury car) but not uncomfortable. We have put the miles on it in all types of weather and speeds. I strongly suggest out the back but put the cutouts on it and run your side exits for show. Best of both worlds for you. (photo showing rear exhaust taking at 95mph on California Freeway playing catch up with the leader)

front exiting like this ? done many set ups with many mufflers and some nascar boom pipes engine size and cr plays in to sound getting it out from under the car helps the 4 inch pipes sound very nice not overly loud just idling but same setup on a car not coming out the sound hits the gound then hits the car floor and bunces all the way out what you get you a drone sound and your teeth get sore on long trips when your fillings fall out
