Smile WRX axleback on a 1.8 L?

A WRX axleback recently came into my possession. I figured I might as well put it to good use and install it on my car. I knew it might not be the right size, and it wasn't! So I come to you, Nasioc, asking for help. What do I need to make this ish fit?

dunno. i always like a welder on hand but I have no idea because i havent seen a wrx exhaust in a while. I put a full 3" borla on my 96. that went well, and all i needed was a welder and a cutting wheel.

It should have bolted right up...

The impreza and wrx are basically the same car. As far as wheelbase is concerned.

What is it about the axleback that doesnt make it fit right?

It's the angle of the flange to the midpipe. Any competent exhaust shop can fix that for cheap. Another option is to use a split clamp that looks like 2 C-shaped pieces with a hole at each end for bolts to go through. Simply clock the clamp to the desired angle and bolt through the axleback, using the original flange to pull things tight.

I ran one on my Brighton for awhile. No difference in power, sound was slightly better, looked better too.

One of the hangers may be in a different position....but Kartboy hangers on the end is plenty to keep it from moving too much.

Two of the exhaust hangers fit fine, the third isn't in the right place and will not reach. No big deal. But the pipe on the WRX axleback is larger than the L axleback. Didn't measure them so I don't know the exact sizes. The holes on the WRX axleback were farther apart than the old one so they didn't line up right, and also it was a bit ****-eyed. It looked like this

So basically i need some sort of converter pipe or something. Completely lost here as I know almost nothing about exhausts..

we rigged one up to a 93 1.8L, we just took a drill to the flange and modified the WRX flange holes to match up with the 1.8's... fit fine everywhere else..

you can see the 1.8 in the middle here


here's a simple side shot.. sorry i can't get under there right now and take a better pic for you, but it really was simple with a drill and big bit.

The larger diameter of the exhaust flange didn't cause an issue? Did you get the angle of the flange adjusted?

Take it to an exhaust shop and have them make it fit. Costs $40-80 at most.

You can either have the modify the midpipe to fit, modify the muffler, or have them make a whole new midpipe (best option) to fit.
