Bought these online for $90 and thought I measured correctly but I guess not. They are too big to fit my car. (e46 mtech bumper) Anyways, $75 takes the set. They are the clamp on style so they fit a wide variety of sizes. Located in Calgary.
Inlet diameter is 2 3/8"
Outlet diameter is 3 3/8"
Length  7 3/4"

Ran this intake for seriously probably 50km before swapping it out for a racing dynamics kit. 3" inlet. $20 takes it.

Not really much to say, eBay vendor sent me two sets and I have no need for both. Never opened, but can confirm they work great. Pics of them installed attached.

 

Most likely not the right target audience. Anyways, maybe someone on here has a nephew or a little brother or someone in need of a wake up call, literally. Well guess what? Your in luck because I have a solution for you. Back in my days of being 16 years old driving around in my Maxima, listening to rap I was probably very similar to the person you have in mind and thought it would be cool to make my entire car vibrate. So what did I do? I went out and bought myself some subs because hey, that was the cool thing to do! Now that I have grown out of that phase (thank god) I no longer have a use for these subs anymore so they are just sitting in my house unused. To be completely serious with you now, these subs have barely been used and I was embarrassed to turn these up past minimum volume. I seriously probably turned it up loud twice. I shared the car with my mom until I got my BMW and she got her Range Rover so like I said, very very minimal use. The amplifier was attached to the inside of the trunk roof via a custom steel rack I built so it would ventilate to the best of its ability. I am asking $300 for the setup which includes absolutely everything someone would need to install subwoofers into their car except for a deck unless they have a Maxima too. Here is the link to the Kijiji ad.

Would be willing to install it for someone on the forum here free of charge if need be.

Hey everyone,

So I just spoke to a guy here in Calgary who can make decals for the forum here. What I was thinking was "AlbertaBimmers.ca" in white writing and a block type font. 1"x9" approximately. However we can order different colours and sizes if need be. In addition, the guy doing this is trying to raise money for a friend with a sick kid who is doing a fundraiser to raise money for the trip to Toronto so all profits will be going to that. I was going to order 75 to start, and more can always be ordered. If you would like to donate to the fundraiser separately let me know and I can get you some contact information.


Thanks,

Ryan
