Great budget exhaust

Recently ordered this from another website and threw it on my 14 WRX hatch. Very quiet exhaust, even considering it's 3 inch. Much quieter than the simple muffler delete I had on the car before. Welds were good on the piece, and the overall quality is good. Only reason I had to take a star off is for the fitment. Tips are ever so slightly off compared to each other, and the pipes either contact the car, or are extremely close to it in some spots. If touching is a major concern, you honestly could just dent it in with a mallet if needed. Overall a great exhaust for the price


This exhaust gave me the note that I have been looking for and was fairly painless to install

Best bang for your buck

Love the sound and the look but it has a little bit of a fitment issue where the left side was a little closer to the bumper then it should but it's a simple fix by bending the exhaust hangers. Easy removal and installation. All the gaskets and bolts are provided and well needed. In the end I love it, love the sound and the price.

Great once modified.

This exhaust became ideal once a mufflershop did proper adjustements ($250) to make is sit perfectly flushed in the fender like the stock exhaust. Sound is gloriously sonorous.


Sounds great, zero rasp or rattles. It has a very deep tone and rumble and for the price I can't find anything to nitpick.
