Invidia N1 Dual Cat Back Exhaust 2015-2021 WRX / 2015-2021 STI / 2015-2016 Forester XT

15 Forester XT. Great looking exhaust. All the welds/hardware are excellent. Goes in really easy did it in the driveway on ramps solo and only took about an hour. Sounds pretty clean I wouldn't say real loud or annoying (but that's my opinion). Does give that nice low rpm boxer grumble.
Does seem to be a clearance issue at the driver-side rear lower control arm. It pretty much just sits against it even after multiple times adjusting. Also either one tip is straight or the other. It's pretty and sounds good but I can't say I would purchase it again.


We appreciate your 5 Star Review! The Invidia N! Dual Catback Exhaust is a great sounding exhaust! It is solid quality and increase hp and torque! May i suggest upgrading your exhaust hangers to larger urethane hangers which may give you the clearance you need! You can search our website or give our Customer Support a call at 860-291-0015 to give you the best option.

Yep. It’s a great choice. 2018 Forester XT

Fit: The install was easy. Everything lined up as it should. The brass colored 12mm bolts supplied to connect the mid pipe to the OEM system cannot survive an impact gun. Ask me how I know.

Finish, initial thought is it is very nice, welds look great and the stainless was scratch free upon delivery. No instructions but I really don’t think anyone would need them.

Sound: it’s louder than some may want but, not that loud. At cruising speed 75mph on the highway at 1800-2200 RPM it does drone a tiny bit in the cabin. When you go above 2000 rpm, you know it’s there. It’s not quiet. That’s what I was looking for though. A nice rumble around town and great tone (low and mid) at full throttle.

It took me awhile to order and decide because the website says it doesn’t fit the 2018 XT. It does, just isn’t updated correctly or there is some performance related reason they don’t market it towards the XT. Maybe they assume the WRX/STI crowd wouldn’t buy it if it is marketed to those CVT turbo Forester dads. Anyway, you won’t be disappointed unless you want something a little more subtle. I would look at the Q300 for a similar tone and lesser volume.

Final thoughts: my neighbors probably don’t love the cold start decibel level in the mornings but, I sure do.


Thank you for the detailed 5 Star Review! The Invidia N1 Exhaust is a quality exhaust that sounds phenomenal ! Thank you for informing us of the fitment to your 2018 XT!

N1 dual cat back exhaust

Sound good, not as loud as some of the others available but good for daily driving. When WOT it is nice and loud. Great fitment and easy install. Only problem I had was one of the new bolts snapped off trying to fasten the cat back to the downpipe. Easy fix though and well worth the money.


We appreciate the kind review! The Invidia N1 Dual Cat Back Exhaust is a great upgrade from OEM! As you said not to loud for driving around but it sounds great! I am sorry to hear one of the bolts snapped during install, unfortunately sometimes that happens!
