I'm about to do the exhaust on my 55 Buick. Unfortunately it's going to have to stay a single exhaust with a y-pipe. Mostly because of the frame design and manifolds. I'm thinking about putting a Smithy on it I'm looking for that kind of like'50s Rumble but I don't want it to be super loud. Like turbo muffler loud would be the max. I used to run cherry bomb turbos on my Trans Am and they were decently loud but not obnoxious, but did get a little annoying on long road trips. Will they be close to that or are they significantly louder? If I get one of the really long ones will that help? Also how different do they sound from a glass pack?
Why not do like the late models do, run a bigger single to the axle, then split it into duals out the back or behind the tires? You can still use a single muffler and have good sounds.
I have been running Smithy’s for twenty plus years on all types of hot rods. Just purchase another pair for my truck project. I like the tone as they age. I mount them with the cups facing forward.
I say it everytime. Brockman Mellowtones made in the USA. Call and tell them what youre working with & what you need & they'll make em to suit. Best sounding mufflers Ive ever heard on an old car.
I ran Smithys on the Buick. True duel, no H or X , and they were quiet at speed. Pipes about an inch behind the rear bumper. The long ones. Lasted 12 years, 20,000 + miles. Ben
My 60 something years of driving experience have shown that where the tail pipe exits has everything to do with that droan that wears you out on road trips. Had a buddy with a 383 Mopar (roadrunner size) in the early 70's who had turbos with turndowns in front of the axle. I rode in it one time on a jaunt 50 miles up the road and back to do something and never got in the damned thing again as long as he had it. I had a killing headache for two days from it. When I stuck the 283 in my 48 I got the stupid idea of putting side pipes on it rather than going to a muffler shop for duals that would have cost about the same. Other people loved of it when I ran down the road and I got compliments on the cb all the time but on longer trips it got tiresome. Had a worn out glasspack on it (still so ) Quick and nasty exhaust install when I put the 250 in it in 1989 in a three week thrash from bare frame to making a road trip to a custom car event at Elma wa. I had had the cab, box and nose sitting here in the machine shed at my grandfather's house for several years. that exhaust exited in front of the rear tire and the muffler is more fake than real muffler. Both my OT trucks the same way, the 71 got the old exhaust off a 64 that I blew the engine up in and sent to the scrap yard. the 77 had a cobbled up mess that was loud and would wear you out. That 454 has an exhaust with turbos with the pipes exiting behind the dual rear tires and has no noise in the cab except when you are pulling hard. Meaning that as long as you get the tail pipe out and away behind the rear axle and the pipe ends out past the body or bumper life should be good.
