I recently read that some of the GLs/GL-10s came with rear sway bars and some came without... well the 86 GL-10 Turbo Wagon I'm looking at came with out so my question is:

 

Will say an adjustable Whiteline Rear Sway Bar fit on the wagon if I'm able to get endlinks and bushings or is there no hope?

 

Next question is: I have a EVO 1 Catback exhaust system from my old Impreza... well the exhaust on the wagon needs some upgrading so I'm wondering if my exhaust that I have will work. What do you all think? The diameter of the piping is 2.5"... I believe.

In order to run a rear swaybar you need the rear "A" arms that have the provisions to hold the bar, you may get lucky and have them, but if you don't you'll have to swap them on, and even if you do, you'll probably have to get some hardware at the junkyard to make sure it all gets fastened properly.

 

As for the exhaust, 2.25 may be a bit big, but with a turbo, thats less of an issue as with a naturally asperated engine, its not the backpressure that you have to worry about, its the flow velocity, between 240-260 fps (feet per second) if its too slow it stagnates and backpressure goes up, and if its too small it can't be pushed out fast enough and backpressure goes up.

Sweeeet thanx! Total noObie question, but how do I tell if I already have the rear "A" arms?
