Full titanium exhaust with stainless downpipes? How is that a full titanium exhaust?

Every day I look around, and if nobody is shooting at me, it is a pretty good day.

Ti catback. Bumping diameter to 2.5"
The secondary cat/downpipes could be Ti, but for longevity in that high heat area of the exhaust we decided on stainless.

Weight has nothing to do with the stickiness of the tire.

I pulled the inner foam out of the steering console while de-stickying it, 3lbs dropped. I never thought weight could be lost there, lol.

Next up for me is coilovers, which should drop a few pounds over the OE units. Followed with light wheels; 2 piece brake rotors (4lbs per rotor) and some Ti hardware (2.5lbs for lug bolts)

Some other areas to think of for easy weight reduction:

Headers would drop the weight of the factory manifolds/cats (possibly SAI system) and downpipes.

Brand of tire. Different tire brands and models have different weights.

Brand of battery. Like tires, different brands and models of a battery have different weight. Generally Deka is significantly lighter than other brands. A smaller battery is also an option.
Please keep us informed as your weight loss project progresses, and what you're doing to reduce lbs. Be interesting to see how many lbs you eliminate and what all you did to get there.

Dropped 109.60lbs with the exhaust while retaining the stock manifolds. Fiammenghi headers & downpipes would shed even more weight.

Stainless:


Titanium:
