That is an interesting insight to me. I have always kept those with my daily drivers. I wonder though if I can perhaps delete a speaker or two, depending on weight...of course.

If no one has weighed their sound system and posted the results by the time I get home (~December) then I'll be happy to do it.

Attached a photo of the HKS 4-2-1 Cat-less headers.

Weight is 6.2kg / 13.65lbs

Note: Weight includes both O2 sensors, and may result in most likely a 0.1-0.2kg drop.

EDIT: Image didn't attach, now there.

Has anyone weighed the OEM front bumper beam vs the Beatrush beam?

Will be interested in knowing if changing to coilovers will save any weight

[Scooby South]

yes it does.. Depending on the coilovers .. I saved about 2lbs a corner with KW Var3 and camber plates

Bill

[Anthony]

I'll be weighing my OEM suspension parts next month. I'm not going to take my coilovers off just to weigh them, but I'll definitely weigh them if I ever have them off.

I'll also weigh the bumper beams. If you want to compare it to Beatrush, you'll have to get the weight of the Beatrush beams elsewhere.
