More progress... connecting everything back up and trying to clean up the hose/wire routing for a "cleaner look."



You can see where the exhaust gets routed here and I've added a bunch of aluminized fiberglass heat shield to certain areas just for good measure:



And it will exit something like this:

Forgot to also show that I wrapped my fuel line in the heat shield material:

If you go back a few pages you'll see the active aero wing that myself and some fellow students made in our last year of university. A new group of students took over the project this past year to build their own control system for the wing and were able to secure some time in the wind tunnel! Unfortunately it's not my car in there, but here are some pictures:





















Cool to see it actually working!

Exhaust is done!













Just need to wrap this last section with the fiberglass exhaust wrap and it's done.

back purging sucks, for the future:

Thanks! I've seen it used before and some guys on the welding web forum also recommend it. Just tough to find around here locally. Closest place that could order it in was a few hours away so I ended up just making due without.

Nice build thread as well, I'm not sure how I missed yours before!

Finished up the exhaust wrap and fired it up for the first time today. I took a video but the mic in my camera doesn't do it any justice. I'll get a nicer quality audio clip tomorrow with a proper microphone.

I didn't hear any exhaust leaks.. finally... music to my ears. I would say that it is about as loud as a stock Viper with it's side exit exhaust. Once the car warms up it quiets down a little and I wouldn't call it extraordinarily loud. I have a few other small details to iron out before it's drive-able so it will be different to hear it under load and on the highway.

My first ever aluminum welds (before cleaning up the tube).



I made a stubby intake from 4" aluminum... going to put a little shield over the filter so water won't soak into it if it rains / during car wash. I also moved the evap canister to make room for the intake.



Everything back in:



Drove it around the block today... I don't know if it's just in my head, but it feel like it's quite a bit more responsive. I didn't even get a chance to open it up.. I think I still need to give the clutch one more bleed as well... stay tuned for a video!

So I'm still working on getting the audio clips. I want to put together an assortment of clips.

However, I drove it around a bit today and I have some good news.. the side scoop doesn't seem to get hot at all. I even let the car sit and idle for a while and I could touch the fiberglass around the scoop and it wasn't even warm to the touch... fiberglass is a good insulator (which is why they make exhaust wrap from the stuff) so that might help.

As suspected, it's pretty loud even outside of the garage... especially above 4000rpm but it can sound tame if you don't get into the throttle too much. I can live with it for now since I don't drive the car daily. In the future if I get tired of it, there are some small "spiral" exhaust inserts, or cones, that I can put in the straight section right before it exits and it should take more of the edge off. It would just require a quick cut and reweld down the road.

Stay tuned for some video!

Nice work on the exhaust. It should sound much better than the stock manifolds.
