67-72 bagged exhaust

[gringoloco]

Looking at this, it seems that there will not be much room to route pipes. What are you guys doing? Ideas? Pics?

Thanks -Chris

Not sure what you're looking at, but I plan to go with a mid-length header and custom tubes and dump my exhaust just after the trans (sort of muscle car style). Just a 45 degree end out of the muffler and call it good.

Man, that is going to be LOUD. I want to get it as far out the back as possible.

I am doing shorty headers, and 3 inch all the way out... i put in a tubular crossmember which will give me some room to run the exhaust through, but i also put in the under bed gas tank which wil make it hard to run the pipes out the back. If i can find some mandrel bent 3 inch tubing i will piece it together and then pull it out and tig weld it. If i can get my motor back in soon, I will get some pics of the exhaust. if i don't and any one else has pics i would also love to see them. could save me allot of time.

I have soempics of the stainless exhaust htat was done on the blue truck that I help put together that was completed backin 2005. Here are the pics I have have at work that show the block hugger headers. Ehaust was 2.5" stainless steel tubing with st/stl Borla mufflers.

I plan on running the Summit welded mufflers with 2.5 tubes. A freind of mine put the same setup on a 383 in a '64 SS Impala and it was perfect. Nice and low rumble from 0-2500 rpm with your foot off, but stomp on it an look out.

My truck is running ghetto straight pipes and cherry bombs now, so I doubt it could get much louder.

That looks like Porterbuilt's dropmember in that truck.....
I'm working on the same problems w/ exhaust right now. I'll most likely be going with the ECE drop x-member and will run the pipes through that and then dump them right in front of the rear end. The currently run under the x-member and I have been dragging the snot out of them. I've got a brand spankin new set of Sanderson jet-coated blockhugger headers waiting to go in but I need to get some other things worked out first.

Thats a Jim Meyer front end. Very pricey. I looked in to it before I found Nathens Dropmember. That crossmember requires you change everything on your front suspension.

I will be using shorty headers from a camaro and dumping it right behind the cab. Before I took it apart for the Z, I had the stock center dump manifolds with a 90 from Autozone and a piece of pipe and dumped it just behind the cab. I made it myself and it worked fine. Pretty cheap too.

im not bagged but it's all above the frame



yea i have a little oil under there

[98L150]

Damian that is how my 72 sub's exhaust is done.

Here are some pics of the blue trucks exhaust:

WOW, that is super clean. Does your bed have a step in it?

[98L150]

yes the bed does have a stepp notch in it.

Here's some pics of the exhaust on Dino's 66. It's dual 2.5" fabricated exhaust (180 mandrels cut and TIG welded together) into a 4" Flowmaster 'Super Comp' muffler and turned down and out behind the cab. It's loud... but cool!

Mine is a 6-banger, so only one exhaust, but you could repeat on passenger side for duals.

I routed my head pipe to the outside of the frame rail just as quickly as possible behind the front wheel (where the frame comes up at an angle to the front xmember). Once outside the frame, it's pretty much a straight shot all the way back to in front of the rear wheels. The rocker hides everything (my muffler is under the cab, behind the rocker because there's not much place after the cab for a muffler on a stock frame stepside. Since going to the fabricated back half, I'll be able to put as big a muffler as I'd ever want just outside the frame rail either in front of or behind the axle.

Oh, mine currently dumps like the last pic in Porterbuilt's post just above.

[Low68]

Anyone with bags have their exhaust run all the way back behind the rear wheels?

Possibly, but the problem is that... for a standard bag setup with CPP notch, the axle bottoms out on the notch, which leaves less than 2" of clearance between the axle and the bed floor. So to run all the way to the back, you'd be laying on the exhaust instead of the axle.

hEY 98L150 I think you forgot the calipers!!!!

[04 orange]

What headers are yall running when the truck is bagged.

[Inthuwind]

I heard Sanderson C5 full lengths will work on Big Block and bagged.

[FnLow69]

either shortys or block huggers

[bodydropped68]

here's one pic i have of my exhaust were it exits,i'm running block huggers and it runs on the outside of the frame then between the frame and rear tyre's following the frame kickup over the axle.

Either of you run into clearance problems with the front tires when turning? Looking at it, it seems like this would be a problem. -Chris

None whatsoever. 27" tire on an 8" wheel.
