Cpt.Fred Posted April 13, 2014 Author Report Share Posted April 13, 2014 (edited) that's all very nice work there, but it's only possible on P15 frames, it appears, since they seem to lack the massive X-member in the center of the frame and don' carry the battery in a case under the driver's seat that is 100% in the way of any exhaust pipe possibly routed that way... prewar frames don' seem to be that roomy unless you're willing to cut them up. edit: self correction! all what i said above only matters if you want to get the car lower (back to topic), because the biggest difference to the original in my case is that i rerouted the pipes THROUGH the frame to get more ground clearance. if you walk down the original road and let them hang under the frame you can pretty much do what you want, i guess... i'm hungry for pics of your under-the-axle-exhaust, deathbound... ^^ Edited April 13, 2014 by Cpt.Fred Quote Link to comment Share on other sites More sharing options...

40desoto Posted April 14, 2014 Report Share Posted April 14, 2014 Nice to see that our old Mopar's are coming up in the world!!! I am an addicted viewer of the HAMB and a year ago you didn't see anything that wasn't Ford/Chevy in our era of cars. Now people are starting to dig them out of wherever and give them new lives. We will still be the unusual cars at the cruises and shows. I was hoping to get mine done and at some car shows before the too many started popping up..(I love having something a slight different) I went to The Grand National Roadster show here in Pomona, California a couple months ago and I must of seen 6-7 mild custom '36 - '41 Mopars. Actually the last pic with the kid Im not sure if it was a Mopar or not? Quote Link to comment Share on other sites More sharing options...

Don Coatney Posted April 14, 2014 Report Share Posted April 14, 2014 Fred, here are a few.....Derek I am curious. why are the clamps installed nuts up? I always use an impact wrench to install these clamps as breakage is minimized over using a wrench. Quote Link to comment Share on other sites More sharing options...

I always use an impact wrench to install these clamps as breakage is minimized over using a wrench. Not sure Don, the muffler shop installed them like that & I didn't notice til you mentioned it. I'll look tomorrow. I agree, it's easier to access the nuts from below.......no smart remarks....I can hear them already! Quote Link to comment Share on other sites More sharing options...
Cpt.Fred Posted April 14, 2014 Author Report Share Posted April 14, 2014 agreed... no comment. no problem with some nice photos, they're not even that off topic since all pictured cars are pretty low... only thing i'd say is that white '41 isn't "mild custom" at all... that's a full blown lead sled to me with tons of body and frame mods, air ride and all... would like to know what's under the hood? thanks a lot for the photos! i think i might change my exhaust a little this year and that under-the-axle-thing looks great... do you have problems when you get the car up on jack stands and the axle touches the tubing when it comes down? also, what diameter did you use? mine is 2" all the way. i also think i might get drive shaft issues when i crossed over to the driver's side like you did. great info here, once again, thanks a lot!

pflaming Posted April 14, 2014 Report Share Posted April 14, 2014 They may have put the clamps with the burrs up so they would not hook onto things like snakes, or worms, or flat head burn tracks! Oh, for the younger set, it's bolts and burrs, not nuts and bolts. Got to learn to be more sensitive these days! Quote Link to comment Share on other sites More sharing options...

Don Coatney Posted April 14, 2014 Report Share Posted April 14, 2014 After looking closer I suspect the clamps are bolted to a pipe hanger. Quote Link to comment Share on other sites More sharing options...
40desoto Posted April 14, 2014 Report Share Posted April 14, 2014 Hey Derek, what shop did your exhaust work? I used to go to a really good shop in Long Beach years back but cant seem to remember. Quote Link to comment Share on other sites More sharing options...

Fred, I'm running 2" also. I don't think the axle came down on the exhaust the last time I had the rear up on stands....I would've remembered if it had. Looking at the pics I posted, it looks like the drive shaft rubs a little where it crosses over.....I'll have to address that. They may have put the clamps with the burrs up so they would not hook onto things like snakes, or worms, or flat head burn tracks! Oh, for the younger set, it's bolts and burrs, not nuts and bolts. Got to learn to be more sensitive these days! Paul, I've never heard the term "burrs" for the clamps. I know there is a u-bolt w/2 nuts....is the "burr" the other part of the clamp? After looking closer I suspect the clamps are bolted to a pipe hanger. Don, correct, there is the metal bracket that is bolted to the flexible part of the hanger sandwiched between the pipe & clamp. Hey Derek, what shop did your exhaust work? I used to go to a really good shop in Long Beach years back but cant seem to remember. Advance Muffler on PCH in Long Beach.

pflaming Posted April 15, 2014 Report Share Posted April 15, 2014 The term 'burr' at one time was synonymous with 'nut'. Now that may have been a regional term but I grew up with 'bolts and burrs', not 'nuts and bolts'. Maybe some one else who is a bit older can comment.

Dave72dt Posted April 15, 2014 Report Share Posted April 15, 2014 Paul, I've never heard the term "burrs" for the clamps. I know there is a u-bolt w/2 nuts....is the "burr" the other part of the clamp? Burr refers to the nuts themselves. My father used the term. I have no idea why they were termed as such. Wickipedia doesn't define it that way either Quote Link to comment Share on other sites More sharing options...

Dave72dt Posted April 15, 2014 Report Share Posted April 15, 2014 Wicki does mention burr haircuts. We had a burr mill for grinding feed years ago and had some burr oaks growing on the farm and it was something I said this morning when outside looking at the fresh snow I didn't need or want.

Bmartin Posted April 15, 2014 Report Share Posted April 15, 2014 So what is everyone's motivation for the dual exhaust? Is a it style choice, perhaps based on how things were done in the past? Or do you actually see a noticeable performance increase? If you keep posting pics of those custom Mopars I'm going to lose my patience and start on the suspension before all the other stuff is fixed. Man those look good!

pflaming Posted April 15, 2014 Report Share Posted April 15, 2014 (edited) motivation for the dual exhaust. . . I have concluded that dual exhausts (1) allow for more air to faster escape thus a freer running engine that is if (2) dual carbs or such are also added so that more air can get in! (3) and sound. I think those are the big three. For me and my liking for the flat head, that is not enough reason for the added expense, and that's not an indictment, just a personal preference.

Don Coatney Posted April 15, 2014 Report Share Posted April 15, 2014 Duals, Mostly the sound and bragging rights. Quote Link to comment Share on other sites More sharing options...
Cpt.Fred Posted April 15, 2014 Author Report Share Posted April 15, 2014 Bmartin, when i did my triple carb project and documented it here, the topic of dual exhaust was very well discussed... the best comment regarding increased performance i can remember was: "dual exhaust is like pissing in a wet suit - nobody notices, but it gives you a warm feeling." i gained a full second on the 1/8 mile, but i did a number of little things to the engine, and to be honest, i think the most effective was a good valve job. if interested, read the full mess here: http://p15-d24.com/topic/22357-201-hop-up-project/?hl=%2Btriple+%2Bcarb and of course don is right, bragging rights! and the sound is much better with a full split system.
