The TurboXS Rear Muffler for WRX & STi is mandrel-bent from 3" Stainless Steel pipe, with a polished 4" Stainless Steel tip for a more classy look than the factory pipe.

Fully TIG welded for strength and accuracy, the TurboXS Rear Muffler for WRX & STi bolts directly to the factory midpipe flange and uses the factory mounting points. Of course, it is also fully compatible with the TurboXS Mid Pipe for WRX and STi!

Perhaps most importantly of all, this thing makes your Rex sound as awesome as it should have in the first place!
