Notes: The crème de la crème of the catback exhausts for your GR/GH Subaru! The R400 boasts robust 3" tubing with quad 4" tips that look as great as they sound! The R400 has become the benchmark for catback exhausts systems for these cars. With fantastic fitment, finish and design, your neighbors will hate you but you will love your car so much more. Much rumble, such wow. If you have the stock downpipe, don't forget to add in this boi from our friends at GrimmSpeed!
There was a small dent when I opened package. Overall the exhaust is perfect and the install was easy. I would recommend this to anybody with a Wrx/Sti.
They were extremely helpful and it came early!
IIR is a solid team...everything came on time, my installer was able to get everything done perfectly, and this Subie rumble is awesome. Wow. I hope the neighbors don't mind the cold starts 😂 .
Keep up the great work, IIR team!
This catback was exactly what I was looking for. Easy installation and if you're looking for a low rumble, this exhaust is for you!
Very happy with the sound and quality on this product install was easy and flanges are slightly slotted to help line everything up no leaks or defects I can see
Over all very happy, for someone that does not like alot of cabin noise I am happy, this kit has just enough rumble to bring out that lovely Subaru sound but not so much that it gets annoying. I commute in my Subaru and in the early morning I do not appreciate noise. This kit turned out to have the perfect balance for me
The exhaust is really nice! Bought with the downpipe. Sound great on my 08 STi hatchback! Highly recommend and the customer service is really good too
Love this exhaust it sounds amazing and fit up great. Highly recommend for the 08-14 Wrx/Sti Hatchback! Drone isn’t bad inside the car at all. Very reasonable. I bought the Invidia high flow downpipe as well and it all bolted up just right and sounds good. Easy install and simple to put together. Well worth every penny.
The drone isn't bad at all, and with a stock cat its pretty quiet until I get on it. Really happy I went this route and not with the n1
Just an overall amazing sound, pretty easy and simple to install. You won’t regret it!
