Hey Shane ..
Y00'll be waking out of TAS with about 10 lbs of paper and catalogs to say the least ..!!! BTW Spoon will be there for the 1st time in 8 years this time ...So this years TAS will be a good one!!

wow, i likr the exhaust, why is it that on TI exhaust the tips have that cool, miscoloration
titanium exhaust tips are colored to distinguish them from regular steel exhausts because you can only achieve this color by super heating titanium. it doesn't happen with steel

I think the last time hitechex and SMSP actually got along on this board was way back when the DC Ti 4-1 race header came out. They both actually agreed ...yes...you read that correctly...agreed back then that Ti was too soft for the street and would not be durable enough.
I think SMSP said that 18 gauge mild steel would save you about 20 lb (not sure) over 16 gauge mild steel...and no-one here would buy an 18 gauge steel race header for their daily driver. So why would you go for Ti weight savings on a daily driver? Not to mention the cost. The DC Ti race header was $1500...what's this one go for?

.....actually, my stock itr exhaust is starting to look like this on the tip! Weird.

Shane, no problem!
I need to give the originals back to you whenever you have time...
My 16g ITR header weighs about 18-19 lbs and the 18g B20 race header without a collector flange came in at 15 lbs witht he larger tubing. On average 16g material is about 32% heavier than 18g. But a 16g header won't be 32% heavier than a 18g since you'd probably still use the same thickness flanges.
Light weight header is cool, but that doesn't mean they would produce more power. I think that header design is much much more complicated than exhaust design, weight saving really isn't as important here.
Dave (SMSP),
you did a calculation of weight comparing a 16 gauge vs 18 gauge exhaust recently but I can't find it on the search. Can anyone link me to that post please?

I really concern about quality too
Lighter is always better. Gaining power is good and lesser weight is always part of my concern.
Some ppl might not care +5-10hp and +10-15LBS

Been There!
The owner of Power House Amuse is a really friendly dude.
He is also really tall ! (compared to me any way) Very clever with ECU tuning. He has a chip for the S2000 and he showed me all of the dyno graphs before and after showing the power gains and changes in A/F ratio. There was a heap of Ti exhausts on the floor in the showroom. He even climbed onto the carbon spoiler attached to the carbon boot on the S2000 to show how strong they are! (It was their turbo S2000 BTW)

Michael D,
18g 2-1/2" OD tubing weighs 1.28 lbs/ft
16g 2-1/2" OD tubing weighs 1.69 lbs/ft
There is roughly 7 feet of tubing in a standard cat back exhaust for an Integra/Civic, so the weight savings is just under 3 pounds. A system built from 18g tubing will also be louder than one built from 16g since it won't have the mass to absord some of the sound. This is why the engine is a little louder when you bolt on a standard USDM spec header (i.e. DC, CompTech) and removed the massive cast iron manifold.
More weight savings can be realized in the resonator and muffler. Calling the rear section of most of these systems a muffler really isn't true. They are just straight thru resonators with a fancy tip. This is the reason they don't do a really good job of muffling the noise. They use a silencer to do this which is actually a device to restrict the flow and allow the rear muffler/resonator to work better (I thought the reason to install an aftermarket exhaust was to get rid of the restrictions). Mufflers are larger than resonators and this allows for more volume and therefore material (stainless steel mesh) to be use to absord more of the noise. This is the one reason why longer resonators work better. So the smaller units obviously weigh less but they can't perform as well as the larger heavier units.
So, if you are really concerned about weight savings I guess you could go with a 18g system with 1 resonator in the rear. But this will be loud for the street but should be fine for the track. It will just depend on how much noise you can tolerate on longer drives and the hassle you may get from the police. You could do a quiet system for the street and then just use some straigth tubing with a resonator and let it dump at the rear of the tunnel for track use. But there are a couple quiet systems without restrictions available.
I know with my road race car that it's about 30 pounds overweight right now. I could spend about $800-$1000 for liteweight wheels and reduce a big chunk of that, but for no money I could probably loose a few pounds myself and have a quicker car and be in better shape.
So, if you want to save those 3 pounds just take some exlax the night before your race.

now Dave, you don't want to be promoting drug abuse on this board
