The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Opinions for dual exhaust

Going to put new dual exhaust on my 62 gmc fleetside. I have a 350 chevy engine. Auto tranny. Straight manifolds no headers. Was thinking about shooting the exhaust right out in front of the rear wheels going with 2 inch pipe and thrush glass packs with a 2" to 3" angled chrome tips. Questions...Should I run it over the axles? Straight out the back? Behind the rear wheels? Give me some advice.

I prefer straight out the back myself, or behind the rear wheel. I would keep it farther away from my ears. You still get the sound. Just not so close. These days I would go with some real mufflers instead of glass packs. They make some real nice ones that sound good and perform well. Glass pack will stay on forever, but the insides don't last.

The problem with exhausts in front of rear wheels is noise, plus if you want to work on the engine when its idling in the garage you will get gassed out pretty quick. I've got a '62 C-10 with the spare in the original spot and dual exchausts out the back that do not rattle or hit any part of the frame. It can be done.

Would love to see pictures too!!!!

I just ran full length 2-1/2" exhaust on my '65. It has 28" glass packs so this should give you a decent comparison. I agree with the posts above, if it's a driver you will want to run the pipes out the back, anything else gets pretty obnoxious.

I ran the exhaust outside the frame rails, worked out well and leaves a lot of access to the rear suspension. Click on this link for photos and a video clip: http://67-72chevytrucks.com/vboard/showthread.php?t=363509&page=6

I had a custom exhaust installed when I ran the 327: 2" pipe with turbo mufflers, over the axle and turned out behind the rear wheels. The guy said I'd like it better than out the back, and I did. With my big mirrors, I could see the little puff every time I shifted, and on cold mornings it was easier to tell when to start pushing in on the choke.
Ultimately, I started noticing a little more smoke on one side, so I put in the 250, hoping to rebuild the 327. I'm still using the one side of that exhaust system! I hope that guy is still in business.

I used to have my exhaust turned out before the rear tires. It was kinda loud with 2" 2 chamber flowmasters. I had it changed about 2 years ago and the mufflers come out under the bed area with turn downs right after the muffler. I used Thrush series welded mufflers 2 1/2". It sounds good and not blowning out my ear drums. Got a couple of pics with exhaust turned out before the tires and with turn downs under the bed. Sometimes I have found exhaust doesnt have to be seen to be appreciated.

sent you a pm

I had a new exhaust system put in mine a couple years ago with 2 ¼” pipe leading into Flowtech Terminator mufflers with turn downs just ahead of the axle. I had been running the same brand and model mufflers for over 10 years, but when all the pipes wore out I replaced them. They are rather mellow and never did generate excessive noise in the cab (and no droning). On the new system I decided to have a crossover pipe installed, and it literally cut the sound level in half. At first I was disappointed it was so quiet, but from the outside it sounds like a 60’s Corvette (at least to my untrained ear). Under full throttle it is still very impressive.

Here are some photos showing the layout:

I like the turn downs because they don’t interfere with anything, and the entire system can be easily removed if needed. They are also great for blowing debris off the driveway, but not so much fun when driving around on dirt.

I have a 64 gmc long bed with 2 1/4" pipes & 30" glass packs. I turned them out in front of the rear tires with 3" crome tips. I love the sound when out on open roads but when I'am going down the freeway next to the center devider it can get loud!If I do it again I'll run it out the back.

I have a 1966 Chevy C20 Custom Camper with a mild-build 327, double-hump heads, a cam and center-dump Ram's Horn exhaust manifolds. It has 2-1/2" aluminized pipe, Series 40 Flowmasters and exits out the rear. It is pretty loud, especially at highway speeds. I think this one would be too loud, if it exited anywhere else, but the rear.

Out the back with stainless steel, angled tips

I have a 1966 Chevy C10 lwb fleetside with a stock 327, a 2-barrel and ceramic-coated FlowTech headers. It has 2-1/2" aluminized pipe, Series 40 Flowmasters and exits out the rear. It is pretty mellow, even at highway speeds. I think this one could exit out the rear or anywhere, in between, and not be a problem.

Out the back with stainless steel, angled tips

I think the trend is out the back, but I think it is purely a matter of personal preference. I like the looks of tips exiting the rear, as well as, just behind the rear tire. The '66 K10 I just finished, turned down just over the rear axle.

FlowMasters turned-down, just past the rear axle

Turned-down to make room for the spare tire

I have Hooker comp headers on a garden variey 350, 2 1/2" w/welded Flowmaster copies turned down over the rear axle. Rumbles, but it's livable on the highway.

I would go with out the back .Still have that rumble with out the constant loud cab.Use a quality type pipe and do it once !I just installed Waldrons and it was worth it .I also like magnaflow mufflers,have them on my daily driver .

Stacks! Just did a set on my dually. 2 inch thrush packs give it a nice rumble and really bellows when opened up.

Thanks for this topic guys... I am working on a 1966 C30 Tow truck. I wasn't sure if I should go out in front of the rear wheels, down in front of the rear axle or out the back.

Out the side might be too loud. Down in front of the rear axle might kick up too much dirt in the yard. Out the back might be the best, but they would not do that on a tow truck. Too much exhaust in the area where they are hooking up.

Oh well.. guess I still have to think about this one!

My profile shows my truck both ways. I like the side better.
