The 370Z Weight Reduction Thread

FricFrac · 06-03-2009, 07:37 PM

FYI and thanks to Dean at Stillen (man their support is AWESOME - can't say the same for other companies I've been dealing with lately).....

Cat back exhaust - 90 lbs + 40lbs from stock - ouch
High Flow Cat - 15 lbs -6 lbs from stock
G3 Intake - under 10 lbs

UPDATE: Sorry there was a little miscommunication and I listed the shipping weight here instead of the actual.... thanks Josh for the real world data although if I drive around with the shipping crate I'm still right ;P

Stock Exhaust

Muffler Section - 26.8lbs (highly inefficient)
Y-Pipe - 11.6lbs
Resonated Y-Pipe - 15.6lbs
Total: 54.0lbs

STILLEN Exhaust

Muffler Section - 39.6lbs (proven huge hp gains)
Y-Pipe - 11.3lbs
Resonated Y-Pipe - 14.4lbs
Total: 65.3lbs

Difference: +11.3lbs and 18whp

I can't see how the CBE weighs 40 lbs. more.

I'm sorry for the confusion, I'll confer with Dean if that's where you got the exhaust numbers. Here's the correct info:

Stock Exhaust

Muffler Section - 26.8lbs (highly inefficient)
Y-Pipe - 11.6lbs
Resonated Y-Pipe - 15.6lbs
Total: 54.0lbs

STILLEN Exhaust

Muffler Section - 39.6lbs (proven huge hp gains)
Y-Pipe - 11.3lbs
Resonated Y-Pipe - 14.4lbs
Total: 65.3lbs

Difference: +11.3lbs and 18whp

Also note that the weight is at the lowest point of the car, over the rear wheels, which will increase traction.

That definitely sounds more reasonable.

Good to have the real data. I'm kinda surprised actually that the wider Stillen piping didn't outweigh stock, and that the muffler difference was the big factor.

I suspect the heat sheilds came into play here.

travisjb · 06-03-2009, 10:24 PM

suppose at least the weight distribution from stillen exhaust goes to the right places... low and back

miguez · 06-05-2009, 12:14 PM

I just PMed Josh@Stillen to confirm.

miguez · 06-05-2009, 12:59 PM

Quick work Josh, thanks!

FricFrac · 06-05-2009, 09:36 PM

I've edited my post to reflect the correct info but kept my old post above it so the thread still makes sense. I had been given the shipping weights rather than item weights.

jmlenz · 06-08-2009, 01:40 PM

I just removed the aluminum hatch this weekend...wish I had a scale handy but I didnt

It is VERY light though! I would estimate it weighed around 35-40ish pounds or so but again, I didnt put it on a scale so that's just an estimate.

Brazilbro · 06-08-2009, 10:46 PM

i'd like a fiberglass hatch for the track pushing 10lb would be nice

travisjb · 06-16-2009, 07:19 PM

side impact protection on the order of 5-6 pounds

LUVZTTZ · 06-18-2009, 02:10 PM

eXo5 has his head in the right place. Play your own version of The Biggest Loser, or hire a horse jockey to run your car. That will be more worthwhile than airbag removal on many levels.

travisjb · 06-18-2009, 02:35 PM

Luvzttz, this is the weight removal thread... we all have different reasons for removing weight from the car... there are some folks that have no purpose for side impact protection systems, and they will find the information useful. And yes, of course, losing body weight is one of the better options.
