Stock wheels may fit.... You could use those for a winter setup?

I thought the 16's were too small for the new chassis?

Nope. 16" wheels will fit. I looked into them when I had my '08 WRX. The stockers from an '02+ will fit. I ended up getting 17" wheels for my snow tires though. I couldn't handle the look of the 16's even just for the winter. I may have sacrificed a little in snow performance, but the good news was that I got to keep those same 17" tires for my STi and only had to buy wheels this past season!

I don't really understand your question. You won't be too low in the winter because you get tires with a taller sidewall. The overall size shouldn't change (yes, technically it's off by up to +/- 5mm) to a point that your ride height will change. If that's you meant with your question, I hope that answered.

Stock tires on your 08 WRX (from the factory) 205/50-17
Sidewall= 102.5mm

on 16's you'd want to add ~25mm to that number for the smaller wheel.

Sidewall= 127.5. 127.5/205=x where x is a %. (=62%)

Yep, math from high school comes back.

So, a 205/60-16 would be close, with a 205/65-16 going just a touch too big.

This might sound crazy, but I'd look into 195/65-16's if I were in your situation. Overall the sidewall would be 126.75mm, which is dang close to the stock diameter. I live in a place where there are enough snowy days with ice pack on the road on lots of streets where I benefit from the tires biting in deeper like soccer cleats. Some climates need tires that are wider, rather than narrower. I know you get some good snow pack out there in MA, so I would do the same. Just make sure you realize you're not on sport performance tires anymore before you go balls out with your driving. That's all I've got.

Brad an easier way of saying that would be to just tell him about a tire calculator.

Tire size calculator

stock 205/50/17 on the 08 wrx is 25.1" tall. a 205/55/16 would be perfect at 24.9" tall. a 205/60/16 is to tall at 25.7" and not great on parts and its more than just ride height.

how do you know? the stock CBE is 2.34". its gonna be hard to tell the difference between that and 2.5" with the naked eye. even though i think the SPT uses a donut gasket which no aftermarket DP's use (maybe cobb). best way if your going to keep the SPT is get an adapter they make for donut to flat and stock to 3".

well my frist clue was from the cat back looks the same size as the pipeing on the muffler and it doesnt have the "heat shields" like on the downpipe/cat. or do they normally end after the cat?

Take your 02 downpipe, pull off your stock 08 dp.
Mock fit the 02 dp and....

Tell us all what and why it doesn't fit.

Lol I know it's been discussed it won't fit.
I'm pretty sure the turbo-downpipe flanges are the same(02-08+). I can't be positive until one is in my hands and I do it myself.
I think the reason everyone says they won't fit the 3gen is the length is different.
I'm going to buy a 02-07 downpipe for my 08 just to make it fit and see why everyone keeps saying it won't fit.
I'm a machinist, so if it gets to cutting and welding, I'll post a DIY.
