Let me preface this by saying I did a search on 'exhaust AND weight' and came up with very little relevant info...(but don't hesitate to point me in the right direction if I've missed something!)

I've been seriously considering buying an aluminized steel Y-pipe and local shop-built steel B-pipe and muffler, due to serious budget constraints. Component longevity is not an issue.

However, I am of the firm opinion that every pound of weight removed from our Maximas is almost as critical to enhancing performance as changing the engine's breathing characteristics to increase HP. That being said, I remember reading somewhere that certain grades of stainless steel (or all of them?) are lighter than typical exhaust shop steel. If this is the case, and the weight savings are significant (i.e. ~20 lbs. or better for the entire system), I could justify the added expense of an all-stainless system.

So, has anybody had the presence of mind to weigh their exhaust components (factory and/or aftermarket) before/during/after the swap?

Thank you in advance for your input.

Let see, before i purchased a muffler, i didn't even consider weight, just style and design...so i bought a straight through hayame muffler, then when i got it, it was heavy, like 15-20 pounds...but it's solid and has not and doubt it will rust ever. But now i'm going to reconsider my exhaust set up and purchase an actual cat-back system.

 

I know that a Stillen Y-Pipe weighs something like 14-16lb's less then a nissan oem y-pipe. Same goes for the B-Pipe, the stock one is a lot heavier. If your looking for some headers/Y-Pipe{I have them 4sale} they weigh quite a bit less, probably about 25-30lb's less.
