Lightest Exhaust, Headers, and Front/Over/Mid Pipes?

[Anthony]

Thanks everybody who's contributed information. If you would like to add information, please link your source of information, or better yet: post a photo of the part on a scale like in the official weight thread. If you don't give me a source, I will use your post as the source. We're thorough around here!

I've also decided to color code parts by diameter. Matching colors = less turbulence = minimized loss of horsepower
2.118"/53.8mm, 2.25"/57.15mm 2.36"/60mm, 2.38"/60.5mm, 2.5"/63.5mm, 2.76"/70.1mm, 3.15"/80mm Unknown

***Note that some measurements may be inner diameter, and some may be outer diameter. Check your sources if diameter is a concern to you, which it should be if you want hp/tq gains***

Based on all this information, the factory engine back system weighs 76.1lbs. The current lightest combination is:

Borla UEL headers, Avo over pipe, Amuse front and catback sytem for a total of 23.74lbs, saving 52.36lbs from stock.

I've also emailed two titanium exhaust manufacturers. I know a one-off titanium exhaust would be ungodly expensive and probably not worth the weight savings, even for me, but maybe a group buy could make it reasonable.

I suppose this is the weight of the stock exhaust from the cat back?

Probably because the headers alone are 20lbs

Weird. When I click on it in the link where I quoted you, it works. But when I click on your link in your original post, I get the message.

Try now, it didn't correct the URL link, only the text link when I made some adjustments before hand, the url link should now be correct

Thanks. I'm listing you as the source on these numbers. I got the same number from Tanabe's website, so I'll use that for that source. Get me some links and I'll update.
