does adding an aftermarket axleback drop some weight?
I was looking into the megan oe rs axle back, because I dont want something too loud, big or angled.
anyhow is there also a notceable weight drop if I were to switch it out?
how heavy is the stock axleback compared to the megan?

i would imagine that a single canister style aftermarket exhaust would weigh less than the stock because it seems there is less piping and a smaller muffler. but im pretty sure that the weight difference isn't really noticeable. i seriously doubt u could save enough weight by switching exhausts to make a difference.

in all seriousness changing stock parts will shed some weight. compare the stock mid pipe to megan, its a noticable difference. as far as the axle back that thing is a monster with that huge muffler.

well Ive been reading up on weight reduction here on the forums and from what I gather for every 19lbs the car gains 1 hp 
I used to have some subs in the back of the car and completely removed them entirely because I thought it was just dead weight and Id rather have less weight for improved acceleration than bass for music. so now im back to stock door speakers only...
anyhow the subs weighed 50lbs and the car did accelerate faster even when it was just a 50lb weight drop. the change was noticeable enough for me to see what else I can do to make the car even lighter. Like removing the spare tire and tools for another weight drop for maybe a day to see how it feels.
because of this I was considering shedding more poundage, does anyone know what the average weight drop is for an aftermarket axleback? if its like a 20+lb difference Id say its worth it because it'll add up when I try to take other stuff out of the car, to make it even peppier.
removing the spare tire and tools alone would drop a little under 30lbs and if the exhaust saves another 20 thats 50 lbs right there. That would mean my car would be 100lbs lighter than what i was driving with for the last year.
if that works well, how much weight loss is the megan midpipe and is it carb legal? and removing the rear seats is also a tempting option and that would probably be another 50 lbs
so as you can see, that it may be a small weight drop per item but they quickly add up.
back to exhausts
anyhow comparing sizes, the exhaust indeed looks humungous compared to these single canister exhausts, so I just thought less metal = lighter weight.
losing a few pounds aint gonna win 1/4 times, but its definately a plus for someone thats using it for DD. where improved acelleration however little it is helps out with the drive to work.
also improving mpg is another plus.

each axle back weights different so it's best to ask which ones you are looking for and HKS is heavy. as for the weight i can agree with you but i threw my spare back in after i got a flat near my place and was able to make it home, would of not went well if i wasn't near my place 
the rear seats weight alot more than 50 pounds, i know i've removed mine plenty of times already. is the megan mid-pipe carb legal, of course not because nothing here in california is and you know that but don't worry about it being loud a raspy because it won't be if you keep your stock headers. also remember that the more power you put into your car, the more it's gonna waste gas.

i know that but for example a intake states that it'll help you save gas and yet it doesn't, that is to what i am referring to although some say a aftermarket exhaust does help out than the stock one but everything else doesn't IMO.

Rule of thumb, for each 100 pounds of weight shed from the car you will shave 1/10th off of your ET in the quarter mile. I don't know the ratio for unsprung weight (IE wheels/tires) but it is greater.
Based on deadlifting both my stock cat-back and my Agency-power replacement, during the install. The Agency Power is close to 20 pounds lighter. I can't speak for axel-backs or other cat-backs as I have not installed or uninstalled them. Every pound helps, but exhaust is not going to buy you much, especially just an axle-back.
