So, I sold my 2012 WRX Catback and my old specialized bike to fund an exhaust build. I really wanted to go Perrin but I was advised from a friend about a shop locally. I was surprised to see 2 other Subaru's on the rack getting exhaust done so I figured this was a good choice.

I ended up going 3" non resonated mid pipe into a 2.5" Y pipe and straight pipe out the back. The exhaust was finished off with tips from a 2012 WRX from one of the cars that was having the same exhaust built.

The sound and quality is amazing and very satisfied with this setup! Best part is that it is capable of bolting up to the stock downpipe

 

So basically 3in to 2.5in straight pipe? Interesting! Post a video of how it sounds

 

Correct! I'll try to get some vids soon

 

Which shop did you go to mike? I want to get a mid pipe made with an electric cutout

 

Mufflers and more in Manteca. This guy does outstanding work!

 

Manteca? Doesn't that mean lard in spanish?

 

I don't see the point of it tapering... Wouldn't you want more flow?

 

For some reason, that's what the shop recommended so I agreed. It does flow well enough for me like this. I'm sure 3" all the way would sound a bit better and flow a tad bit more
