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.

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.

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.

QUESTIONS & ANSWERS

  • Q: Stock hatchback sti 08  Vic1 year 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.
    • 0 of 0 people found the following answer helpful

      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.

  • Q: Piping   orlando.l.rivera09331822 years ago

    Is there any muffler or restrictor in the actual piping? Or is it just the flex point and straight 3 inches of piping all the way back to the tips?
    • 0 of 0 people found the following answer helpful

      A:  Flex joint, resonator, piping and then the muffler. The pictures are accurate as to what the exhaust will look like. And the actual tips are just under 4 inches.

  • Q: Flanges  Colin3 years ago

    Do I need to purchase a donut gasket or other flanges to fit this to a stock downpipe?
    • 0 of 0 people found the following answer helpful

      A:  You will need Grimmspeed's Adapter to ensure a leak free install with your Stock Downpipe. You can find the adapter by searching Part # GRM 077046

  • Q: Re-Tune?  Harrison3 years ago

    I have a stage 2 tune on my 13 WRX and already have a catback installed. Will I need to get a re-tune if I install this exhaust?
