I decided to go with Fast Intensions after hearing the FI cat back plus LTH combo...simply put...HAAAAMAZING!

Question2: I'm researching wheels. For obvious reasons Forgestar F14's are popular but I am not sure I like them (although I recently saw a set with the dark bronze finish that actually looked good). Do you all know of any wheel under $3k that comes close to 23 lbs and is a 19x11?

Nobody?

Has anyone done this, or considered this? Interesting site.

Sounds kind of hard-core to me. I guess if you were having your engine completely rebuilt and fine-tuned for balance anyways, you may as well try something gutsy like that

I wouldn't tear the engine apart just for the lightening though.

Seibon now offers dry carbon hoods and hatches. Something you may want to look into. Im also curious if anyone know any weights on them yet?

How about gutting rear hatch too and then installing plexiglas ? Weight savings?

anybody look at Litespeed Racing? its basically a Titanium resonated straight pipe they claim exhaust weighs 14lbs excluding the Y-pipe as far as i can see sent them an email. its pricey 3600 or so but -40lbs and adding 14whp and 16trq (Dyno sheet on website) could be a recipe for success. Loud i would bet though good for a track car haha 370z Full Titanium Race Exhaust sounds pretty good as well

kcquinn49 · 09-24-2012, 08:15 PM

Yes, I've been to the litespeed site. They also advertize here. The 14 whp I believe was on a Nismo, so it might be more on a base coupe.

I picked up a Siebon dry carbon hatch. Will be interesting to see weight savings with this piece

Mike · 11-02-2012, 08:31 AM

I lost 16lbs with headers

Please post both weights, Siebon and stock, after you weight them. How much for the dry carbon hatch?

Were those long tube headers that replaced both the stock headers and the stock cats?

They were short piped headers. Just replaced the manifold.

kcquinn49 · 11-04-2012, 12:37 PM

thanks for the quick reply. I checked this thread for weight of the stock header and couldn't find it. I only found that the Fast Intentions long tube headers, as a pair, are 17 pounds lighter than the stock headers and cats that they replace.

What was the weight of the stock headers?

No, short tubes

Extra pound or so you can shed without really altering the look of your car (for those of us who aren't track monsters like Spohn, Mike, or wstar, lol)

For all the Nismo guys... Removing the front and rear body dampers saves 8.4lbs. I can't hear/feel any noises/vibrations or anything after I removed them.
