Building a Scorpio exhaust

Post by tvissoc » Thu Oct 07, 2010 2:55 pm

Wish me luck. This weekend I'll be attempting to build an exhaust for
the Scorpio. My exhaust has pretty much disintegrated from the cat
back, so I'll be building this thing pretty much from scratch. I've
purchased two mufflers and enough pipe to do duals, but will probably
just do one side for now and make it dual in the spring. I have a
spare Y pipe to hack up and haven't decided if I will do an H or X
pipe for the dual setup. I'm also not sure how I will connect the
front section to the rear. I know I should make it so I can remove
the rear section easily. So, do I do a flanged connection? A slip
connection with clamp? One of those fancy band clamps?

Here is what I've purchased to work with.

Two of these:

And a pipe kit from:
http://www.speedwaymotors.com/Mild-Stee ... 25216.html
I thought this would be a good kit to start with, since there are
plenty of slip connections to work with. I'm still getting up to
speed with welding, so I think this will work best. It might look
pretty crazy when all fitted up, but I think it will be easier to weld
a slip joint than a butt joint. And, if all else fails, I'll throw
clamps on.

Anyway, just thought I'd put this out for comments if you're
interested. Perhaps you can talk me out of the madness or pray for
me. Beer would be good too. I'll be sure to take pictures to allow
praise and/or criticism.

Flange, and make sure to get some that have readily available gaskets. The Scorpio gaskets are impossible to come by. And in your part of the country I implore you to use SS fastners everywhere, to make your life easy for tear down in 20 yrs...

Good luck! Please take some pics when you can. I need to do exhaust surgery on my Scorpio some time. I would like to see how yours comes out.

Success! I took some pics, but they're still uploading to my Picasa album. Ok, they're done. Have a look:

Seems that my muffler choice is really only good for a single exhaust. Much too big to fit a pair under the car.

Did you consider getting a dual inlet/outlet muffler? That would allow you to run dual exhausts if that's what you're trying to do. And, of course, that leaves the two mufflers you already have, but is just a thought.

Your welds look great, I wish I had those skills for when I put a 3" exhaust on my XR4Ti.

I've thought about mufflers like that in the past. I chose these mainly because of their cost.

Close up, these welds are pretty ugly. I'm getting better, but these welds would never work on something like intercooler tubing. I'm sure I have leaks.

Thanks!

Yep, you're right. Shoulda had stands under there. I did know that if a jack slipped, I still had enough clearance. I know... flirtin' with disaster.

Yeah, that was some mandrel bend art. I still have all the U bends and 90s from the kit.

Can anyone guess what I made the muffler hanger out of? Hint: It is an XR part and both ends are cut.

That looks like it's just about 10 mm in diameter.

Lookin' good. How's it sound? Looks like you might have room to tuck the second one next to the gas tank if you needed to.

Hint #2: The part is found in the interior of the XR.

I actually wish I would have tried that first (prop rod). It would have been WAY easier to bend, but may have been too floppy for the muffler hanger. For the rear hanger, it would have been perfect.

Sometimes I'm glad I'm a packrat, when I'm searching for bits to fab up something like that. Also, like the flange I harvested from a spare Scorpio Y pipe.
