First off, here it is, in possibly the last drive of the fall. We've been pretty lucky to have such nice weather so far. Note the fancy headrests keeping the occupants a little safer. We (wife, dog and I) actually got to go for a cruise... I think it's the first time she has been in the car under its own power. And she liked it! That's a big win.
So I had a burst of energy to get the exhaust fitted with a ceramic coated B20E manifold and coated downpipe.
I got the exhaust mocked up (that middle stud did get replaced with a longer stud btw), with the manifold in place and the downpipe. Pretty straightforward so far.
Well, this doesn't look right. Why is this pipe so high? It looks like it'll hit the crossmember and not even line up with the resonator.
Yeah, this isn't right. Although I got my trans mount boxes moved forward as part of my floorboard replacement, this is a Volvo kit for a Volvo car. What gives?
I'm pretty much hitting everything on the way to the back of the car. This isn't cool at all. So, off to the internet. What I find out is that the B20E exhaust manifold is the same height as the old stock manifold (or so I am told, I don't have 2 here to compare). Some people say on the web that, yes, they did have to get the pipe bent; or No, they didn't have to get the pipe bent. What I do find out, is that on VP's site, it literally says for the 2" sports kit "Complete kit, Automatic transmission cars will require modifications.". Well, it doesn't really state what those modifications are. But hopefully 2+2=4, and this is the part that needs modification.
This is a bummer cause you cannot bend a ceramic coated pipe. So, off to VP once more to get another pipe. Live and learn, fit all the parts first, then do the pretty stuff afterwards.
You can see in the background that the old header is on the floor... it did its job, but I wanted to go to something more Volvo-y.
So, off to my local trusted muffler shop. I marked the pipe where I wanted it bent - through measurements, I figured I needed a 2-2.5 inch drop on the pipe. This requires 2 bends, one to drop it, and then another further down, to bend it back UP to level it out to meet the resonator. They didn't have the car, and since I either didn't want to take the car to them (cause I hate people working on it), and I wouldn't drive it there and disassemble it, I just took the pipe. Dude said he could eyeball it, but it wouldn't be perfect. First fitment, well it certainly is pointing down.
I mark the pipe to where I think it needs to be back up. During this time, I hung the rear of the resonator off the donuts, and used a floor jack to get it level, and the measured the difference. About another 2.5 inches back up. Back to the muffler shop.
Ok! Not bad at all. Both pipes are lining up, and I'll be darned if the resonator is almost exactly level. Not bad at all, I am taking it!
Now of course the fiddly parts, putting it all together. My brother in law was kind enough to come over and help me out. One note, is that the overaxle pipe can fit both ways. One flat length is about 11 inches... the other is about 13 inches. The 13 inch section attaches to the rear of the resonator. The previous mechanic who I had work on it, had attached it in reverse to fit a different resonator, in order to fir that header in the previous picture. Once the pipe was turned around, it fit right together nicely. I got some band clamps off of the jungle site, I never liked those u-bolt things and the look of them turned me off. I think these look nicer anyways, and they fit well.
Resonator just clears the back of the passenger floorpan.
The donuts were fiddly to fit up, but seemed to hold well.
Just another shot of the piping to the muffler. It does get fairly close to the mudflap but it does not touch.
Note, the muffler was rotated down at the time. The internet did not appreciate this fact, in that everyone told me I was missing the tab. I was a bit lost as to how to attach the rear muffler to the car. Is there a specific mount? In the end, I just used a muffler mounting bolt to tie it up with the fabric strap. People say that those straps have broken in the past, and some have replaced it with a rubber isolator mount (the Touge Tuning kartboy Subaru 1" Extra Long 15mm mount, 1002-07-KB-011XL-15mm is what was suggested).
I cleaned this up a bit after this shot was taken, and added a nyloc nut on the end so it wouldn't easily shake loose.
The tailpipe fits much better as well, closer the bumper and more to the inside of the car. I think it sounds great personally, nice throaty sound, if I can ever hear it from the agricultural lump that's in front of me
Stepped washers! Almost forgot to add this in. So when you have a B20E exhaust, and an aluminum intake, when you go to bolt it to the head, you'll find that the mating surfaces are offset. This means you cannot use those flat conical Volvo washers like you may have used before. I contacted Cameron at Swedish Relics and tried to purchase a set of stepped washers from him, off of his website. Try as he might, he could not navigate the paperwork needed to send them up here. But, he did recommend getting chrome spacers and modifying them to fit the configuration. Top man.
So, to the jungle website once more and picked up 4 Hillman Group 943075 Chrome spacers.
A few cuts later, I think the measurements were 5 mm and 5 mm for the thicknesses...
And voila. Not bad for a hacksaw and a couple hours. I don't have many metalworking tools, if at all.
And you know, they don't fit too bad! I think I will install longer studs in the entire head just to be sure. The end of the studs are flush with the nut. I did pick up some longer studs from VP, so that'll be a springtime job.
Another shot of the washer. It does the job, I have to say.
I also replaced my OD switch with an LED switch, and no my overdrive works like a charm. Either I was burning out switches before, I am not 100% sure. But now it works flawlessly. I was buying Lucas switches for a more authentic look, and they were kinda garbage. This switch is rated for 25 amps. Link is below.

I have an new reverse switch but when I ground the wire off the relay (in place of the switch wire to simulate the switch grounding out), I blow a fuse. I need to think more on this, I might have other issues. Please keep in mind this car was pretty butchered when it went to a manual transmission, from an automatic. I was looking at the Manual schematics and finding odd wires... until I looked at the Auto car schematic. Then it all made more sense. I have everything identified, but there might be more at play.
I also though it was a nice idea Volvo had, to run all the electrical from the back of the car, OVERtop the doors, that way it wouldn't get damaged by water, impact, etc. They knew what they were doing!
Just popping this pic here for future reference... I'd like to figure out my Smiths tach as well to hook up to my 123Ignition. To the internet!
