Well kinda a long story as to why I ended up with my Tribeca but it invalved trading in a WRX and a Baby on the way so trying to make the best of it.

So fare I love the car by far the best SUV I have ever driven. I have a set of springs setting in my shed waiting ot go on and I have some custom doorpanels almost ready to go on. and I put a sub in the back with a custom box that retains the use of the back. As soon as the stereo is done I will post pics. I plan to get some 20" black rims as the b9 is black. I will also be doign a cusotm CAI and was goign to do an Exhaust but had issues with it and in the process of returning it. But hope to get a differant one.

Well there is a few pics of the progress. I'm still working on it hope to have it finnished this weekend. all except the secand amp which will power the front sepakers and there not in yet.

AS soon as I get the springs on I will post pics.

And some pics of why I couldn't use the exhaust.









It doesn't look liek it in the one pic but the Y pipe is centered on the stock one and in the one showing both mufflers from the side the one does stick out further then the other. The company was going to send me another Y pipe but that was three weeks ago and they are telling it will be 3-5 more weeks before I will get it. So I filled with paypal to get my money back.

How about just the mufflers bolted up to the factory Y-pipe? How do they fit? Are the hangars for the Legacy mufflers in the same location as the B9?

Not sure the shope that I took it to to install it said the hangers wern't right and the mufflers hit the spare tire cover. biggest differance is the size of the pipping the stock is like 1.5 after the Y but this is 2" after the y and the mid pipe is 3" versus 2". If I have time tomarow I might take it down to the shope and remove the stock exhaust and try and line it up.

Well I tried to put the exhaust on again today figured out that I would need to remove the spare tire cover and it should fit after that. So I removed it and figured out that the Y pipe was all wrong and the hangers on the mufflers are all wrong. What I don't know is if the exhaust wasn't made right or if the legacy exhaust is just that differant. I have a case filed with paypal to get my money back for the exhaust so will probely just do a custom exhaust myself. :mad:

Too bad it didn't work. It was worth a shot, though. Have you thought about going with a custom setup? What about removing the resonator in the center? Are you looking for more sound or performance? I would not see a need to to increase pipe diameter as it may move the torque curve back.

I'm looking for both performance and sound. The mid pipe isn't the big bottel neck its the Y pipe thats the issue. After all exhaust is only as free flowing as its smallest point. Before I got the tribeca I was big into doing 4 cylinders and if you swaped from say a 2.25 to a 2.5 you would not lose anything you would gain asooming you did it right but if you went up to say a 3" it would loose power. What I don't understand is the pipping on the H-6 is the same size as the H-4. Logic would say that you should make it larger. My plan is to do a custom exhaust I might leave the mid pipe and just do the Y pipe and mufflers. if I did the whole system I would make it 2.5" then 2" after the Y. Having trouble finding some good 2" mufflers but might just have to settle for some 2.25 ones. I plan to later on make some headers that will lengthen the primaries, that will help with the low end power. Going to also play around with a steped design to try and help with the top too.

Alos looking at the springs I have. What apears to be differant is the springs are a much lower spring rate Phyisicaly they have the same amount of coils but the ones off the legacy are about 3/4 as thick. So logic would say that with the softer spring it would drop lower and cause there softer it would still ride good might even be softer then before. What concerns me is this might cause more body role. Going to look into a sway bar but the rear sway has a curve in it to clear the spare tire cover but I think I have a way around that.

Might want to try an aftermarket Legacy spring with higher spring rates with very little drop. I'm thinking pinks or Prodrive (about .5" drop). Are the top and bottom of the Legacy springs the same as the B9? Good luck on the sway bar. It is very different than the rest of the fleet.

OK, more updates. Took a gamble and ordered a leagcy strut brace. Went witht he cusco E-bay clone. and it doesn't fit at all. Not even close. Bolt spacing on the struts are differant and rotated about 45 degree's compared to the legacy and the shock towers are about 2"'s further apart. Going to pay a visit to my local fab shop to see if the can make me some new strut mounts so I can at least use the cross bar. This woudl tend to make me think that a front swaybar will not work either.


Yes the tops and bottoms of the springs are the same. This leads me to think that the struts might interchange as well. if they do interchange would make a good cheap swap for the leagacy guys to get a stiffer ride without any drop for off road use.

I started a custom front grill last night and going to post pics when I get home from work today want to see what people think.
