Features & Product Details

RallySport Direct proudly carries a large selection of quality high-performance master-crafted exhaust options brought to you by Invidia. 

 

This is the Invidia N1 Cat-Back Exhaust System. The N1 is one of Invidia's most popular cat-back options offered in their catalog due to the quality stainless steel construction that combines smooth bends with an increase in piping diameter. This allows for an unobstructed flow path for the exhaust gases to exit which will increase both the horsepower and the torque while improving the overall throttle response. Additionally, users will be rewarded with the race-inspired sound this exhaust system will create which will make the overall driving experience much more enjoyable. 

 

 

 

DETAILS:

  • 304 stainless steel construction
  • 3-inch piping diameter
  • Dual-exit design
  • 4-inch polished stainless slash-cut exhaust tips
  • Includes silencer
  • Improves both horsepower and torque
  • Reduces turbo lag
  • Saves weight
  • Exhaust hangers welded onto the OEM locations to make for a direct fitment
  • Includes new gaskets and hardware for the installation 
  •  

     

     

    NOTE:

  • The Kartboy standard-length exhaust hangers will not work with this particular exhaust system

    This is every bit as nice as the Cobb turbo back I was looking at, and the fitment is almost too good. It went in easier than the stock stuff came out. Just the right amount of rumble without being abnoxious, I also have the resonated downpipe and it’s just right. Rumbles and screams when you punch it, but just right.

    What a great product. It was really packaged well, the parts are gorgeous and RallySport Direct shipped it really fast. Install was cake and it looks fantastic. The sound is amazing without being too loud or drone... much. I'm absolutely happy with this. I did get the GrimmSpeed OEM Downpipe to 3in Cat Back Adapter and am glad as it makes the fit so much better.

    Hardest part of install was lifting the car and getting the old one off, curse you NY winters and rust! Sounds great no rattles with stock hangers. Was able to get it all done in 2 hours. I can drive normally with out getting noticed but if you step on it you’ll love it. A bit of a drone around 2.3k - 2.6k rpm under load but otherwise fantastic. Pairs very well with an accessport and down pipe too. Nothing but smiles. Also great delivery time from rally these guys and gals are great!

    Pretty Loud 6 years ago

    This is pretty loud. Haven't really stepped on it but when you go past about 3500 rpms is when its the loudness kicks in. Paid 100 bucks at the muffler shop to have it installed. The guy said it fits perfect. I bought two of the kartboy extended hangers but only used one of it for the middle past the mufflers and a little bit behind where the spare tire sits. Honestly was expecting it to be louder but its still a big difference from stock and its a great bargain for the price. Sorry if the photos are sideway, don't know why its uploading that way.

    Picked this up during the Black Friday sale and was it a sale... It was a straight forward install and pretty simple. Would've been a lot easier if the car is on a rack. Overall I'm very happy with the way it looks and sounds. I was expecting the N1's to be a lot louder, but many others have already commented that its no louder then OEM at cruising, but when you step on it, you know it. I'm at a stage 1 (Cobb Big SF Intake + Invidia N1 + Cobb OTS tune). Next I'll be installing the Invidia resonated downpipe (some other goodies) to put me at stage 2 along with a visit to the local tuner. I've been told that this will definitely make it louder.

    • Q: N1 fitment & Hangers  Reese5 years ago

      Do I need to purchase an adaptor, grimmspeed adaptor, if I wanted to connect my Cobb catted downpipe to the Invidia N1? Also, would the stock hangers make the tips hang to low because I would prefer a high and tight fit.
      • 0 of 0 people found the following answer helpful

        A:  An adapter is highly recommended if installing with a downpipe that uses a Donut gasket like the Cobb or OEM. The stock hangers generally work well but a stiffer option like the Kartboy hangers can be used.
