Invidia N1 Cat Back Exhaust
Subaru STI Hatchback 2008-2014 / WRX Hatchback 2011-2014
Features & Product Details
If you are looking for a great way to squeeze a little extra performance from your vehicle, then you will be pleased with the Invidia N1 Cat Back Exhaust System. There are several performance attributes that makes this an excellent upgrade. This exhaust system has been made from 304 stainless steel and features 76MM piping. The exhaust has also been designed with minimal bends to reduce the amount of turbulence during acceleration, allowing the engine to exhale the exhaust gasses with less restrictions. This means you will have improvements in throttle response, along with increases in both horsepower and torque.
This exhaust will come with a beautiful pair 101MM polished tips on premium mufflers, and the exhaust hangers are welded onto the stock location of the pipes so you don't have to perform further modifications.

Great exaust sounds good if you have a stock down pipe it's not to loud but it's still loud enough not much drone great exaust!
So install was not that bad especially if you have another hand to help. The sound is incredible, with just the stock DP and the cbe it has a deep rumble to it and is definitely loud. Ha I woke the neighbors up when I was doing a rev test with my buddy. Definitely worth every penny, recommend getting the stock DP to 3" cbe if you have the stock downpipe. Buyyyyy it, you know you want to.
I couldn't be happier with this exhaust. It's definitely loud, especially on a cold start, but not obnoxious or ricey. It has a very low rumble with a lot of bass, I get a ton of compliments on it. Perfect fit with the stock exhaust hangers and the dual tips look awesome. Tons of reviews complain about the drone.. if you don't want to hear that Boxer rumble, keep your car stock.
Perfect fitment but too loud inside the car and drone alot
Very pleased with how it sounded, very easy to install And really straight forward, took me about an hour and half to instill and install new exhaust. I had read the welds were not very good mind seemed very done considering I weld for a living. Only thing is the I knew before purchasing one the left exhaust sticks out just a tad more But thankfully I'm OCD so it doesn't bother me. Shipping was amazingly fast super happy about that, will continue to shop here for sure.

Q: Stock hatchback sti 08 Vic3 years ago
My sti 08 is stock, do i need to do a tune if i put the n1 on? I've heard that it could do damage to the engine if you do mods and no tune.

A: A Catback alone like this one will not require a tune. Tuning would be required if you change out the downpipe as well so that might be what you heard previously.
