Post exact weights of weight reduction you have done!
SH10 3" 304 Stainless piping with a wall thickness of .120" weighs roughly 4.33 lbs/foot.
SH10 3" Titanium piping with the same wall thickness weighs roughly 2.49 lbs/foot. About 43% lighter.
That's assuming you are getting a true titanium exhaust throughout the entire length. Some manufacturers claim its a titamium turbo-back exhaust system but only the muffler and tips are titanium. Just be a smart shopper and cover your bases before you commit to anything. For the cost, I would find more weight savings elsewhere for the same money I bet.

Ya i have definitely read into all the ones on the market... Most are crap. I already have all of buschur's weight reduction parts, pulled the dash apart, and everything else in this thread shy of drilling holes/ chopping the wiring harness haha

Any weight to be lost by swapping exhausts? I've been looking into titanium alot lately. Anyone know the weight per foot on 3" titanium compared to 3" SS? I've looked at every titanium exhaust on the market and haven't been able to justify giving up my buschur exhaust (both sound and weight wise). I need to go back through and read the last 20 pages or so since I haven't been following too close lately
If you are after light weight, you sure as hell aren't using 0.120" wall tubing for an exhaust.
By Cost
0.065" Aluminum -> 0.704 lb/ft
0.035" 321 stainless -> 1.142 lb/ft
0.035" titanium -> 0.637 lb/ft

^ If i wasn't in a Ti kick...
I'd do an .035" wall 321 exhaust with 2 burns mufflers. 1 used inline and one at the end of the car.

Obviously whether or not spending big money on a full ti catback is "worth it" or not is a personal decision, but here are the exhaust weights I have documented:
OEM ’06 Mitsubishi Lancer Evolution 9 catback exhaust – 36.0 lb.
Agency Power 76 mm (3”) catback exhaust w ti muffler/tip, stainless piping, w/ hardware – 21.48 lb.
Mine’s ti 80 mm catback exhaust w/ hardware (2 tension springs) – 11.52 lb.
DIY mild steel 3” turndown pipe with 02 bung, total length 18 1/2" from flange to tip – 4.22 lb.

I have been using a 3.5 dp back aluminum exhaust with a Ti muffler for 2 years now without issue. Just go with aluminium. Cheaper then Ti but weighs nearly the same.
