This is by far the best exhaust for the price you can get. If you're looking for a race car sound and not an invidia fart cannon. Not to be a hater. I just personally dont like there sound at all. Sounds like you have a really aggressive paper shredder behind you. Anyways, If your looking for that genuine rumble. Subtle but sweet in the lower end of the rpms. Which is nice if the police happen to be behind you. Or you dick neighbor. but a deamon when you get on the gas. This is the pipe for you. It looks great. Don't be worried about the empty space it creates. I over thought that alot. It allows you to acctually see the exhaust more from the back. When I got it installed the guys at the shop said that this was the best exhaust they'd ever seen for a subie. Easy to put together and beautiful looking from the back. Best of all though. The sound is all around the best from any exhuast for subaru he's installed. Even wanted to go for a ride to check it out. It's not quite but it's not terribly loud my girl friend hasn't even noticed I put this on. Mind you she could care less about cars. If your on the fence. Don't be!

Sounds amazing. Ultra Light. Cracks at welds :(

This exhaust has been on my car for roughly three years. Two years into owning it, one of the welds in the bends Tomei welded. Figured it must have been a fluke and had a local machine shop the specialized in Titanium welding repair it, only for 10 months later another welded bend to break. Really disappointed. Loved the exhaust but too many repairs, and too hard to find places that will repair it.

A weld on one of the bends right after the rear diff completely snapped after a little less than 2 years, unacceptable in my opinion. The car is a daily and hardly ever pushed hard, hardly ever in boost. Certainly sounded awesome and was super light. I guess it was maybe too light/thin for city driving where roads aren't always completely flat, I'm sure this probably would last longer in dryer areas with perfectly flat roads but still, I'm disappointed...

Im not big into racing or anything like that. I love my 2014 wrx hatch the way it is but i feel that the driving experience is so dumbed down because of the stock, muffled exhaust. So i decided to get this and boy am i glad i did. It is a bit pricey but once you see the quality of the parts first hand you wont regret the purchase. Im glad i did not settle for the less expensive invidia exhaust. Plus you get the well known service from rallysport direct. It arrived here in almost no time!! Thanks! Sound and look of this exhaust is to die for!

Excellent Exhaust

  • Q: Reaonator  Ahernj62244291 3 years ago


    Sorry. Does this come for the hatch without the Reaonator. I noticed the sedan does .....

    • A: This setup includes the resonator.

  • Q: Resonator  Ahernj62244291 3 years ago


    Does the hatch come catless / resonator-less ???

    • A: Catback systems do not have catalytic converters, but this system does include a resonator.

      Nick S. 3 years ago
    • A: Is their one that comes without the resonator as well. I noticed for the sedan is does. What about the hatch.

  • Q: Who has a hatch and can comment on drone?  Subimon42 4 years ago


    I've got an SPT exhuast, no cat, not resonator. So I'm looking for an exhaust that won't drone. The Q300 has been known to drone on hatch's, can someone confirm where this exhaust stands on droning? It appears this exhaust lacks a resonator as well.

    • A: This catback has a resonator built into the midpipe and the drone is not terrible, but it is noticeable.
