Made some twin 3" exhaust tips, not quite happy with them/too wide so going to cut/make the tips closer together to fit better in the bumper opening.
Bought some aluminum sheet to make the hot air ducts, hopefully get some chance to work on them this weekend in between family/halloween/work stuff.
Weight loss 36lbs, but probably need to add a few pounds for the hot air ducts. Plan to redo the corner weight/check ride height afterwards.
Ted those look cool! problem with a lot of the 'twin' tips are that one of the 'tips' usually isn't functional, those look like there's a side hole to connect the smaller 'tip' but not sure how well that would flow. Also my entire system is 3", wouldn't make sense to step down to 2.5" at the tips.
Will take some pics with the car on the ground the next time the sun comes out, which may be a few days here in the wet north west.
well I hope this isn't a disappointment, I did try to make a couple of versions of the heating ducts but could not make them work, not enough space even to use the orange flexible tubing. In the end, I used some semi rigid aluminum air duct, doesn't look good but functional, weighs nothing. They might fly off but are easy to replace
You could also try what I did - use 2.5" SS tubing and ovalize the tubing in a vice - then start routing. Lots of angle cutting and fitting work though. Its is tight though, and i think your positioning is a bit different than mine - the spacing looks tighter. next weekend for a sound comparision?

Sure. Even this eve if the weathers' not too bad. I think both you and Knight have my email that goes to my phone to coordinate if possible.
My wife says it's too loud. I had a car alarm go off in the car parked next to me in an underground parkade. Considering making removable tip inserts to see if I can tone it done by a few DB.
I think it would be loud given you have essentially straight pipes after the turbos - with a bit of sound adjustment but no muffling. I tried that and it was too loud for me, especially coming home late, so I ended up with modified mufflers. Even with my current setup I get a few comments. :-)
Ok, will get an email trail going - nothing booked into the shop on Saturday morning (yet) so that might be a candidate. Will need to bring the camera/microphone so record the three cars side by side.
Too loud????? If it's removing dental fillings from a drone maybe, otherwise no. My system is empty also, and it's very "pronounced" :-) It's how these cars are meant to sound, not the neutered banker/dentist commuter car that some are. Can't wait to hear them.
Sat morning would work for me
Thinking about it more, I think I'm just going to start off by capping off one, two or even three of the tips to see how it affects the sound!
So don't laugh...
made a couple of caps so I could cap off one of the twin tips.
and removable steel wool packing that I could use behind the cap.
There are 3 options and 2 conditions for each option where I can check the sound ie.
1) no caps, at idle and off idle (say 2-3K rpm)
2) caps (no packing), at idle and off idle
3) caps/packing, at idle and off idle.
Which condition do you think would be quietest i) idle and ii) of idle?
There is 4-5 db difference between quietest and loudest at idle which was a surprise to me.
(I was capping off the outer most tips but I guess I could try capping off the more medial ones instead which could also affect the sound
