  • Is there any major difference in the sound from this than if it was only be the invidia cbe??

  • my wrx is pro tuned so if i switch my HKS hi power for Invidia N1 race, do i need to re tune or should i be fine?

  • nice flip flops lol

  • So whats up horsepower wise with when you added the EL headers?

  • @lilstahlly22 Cruising on the highway, there is definitely plenty of drone - and catless would only make this worse. In fact, highway drone is what pushed me to search for something quieter. After a few long trips with that sound level of drone - it gets old real fast. (sorry, had to split my comment up into 3 parts due to YouTube limitations)

  • @lilstahlly22 The N1 catback is a great exhaust - but after 3 years of daily driving with the same loud sound - it can get a bit annoying. To answer your question more specifically - yes, there were times where I'd be driving with the N1 street at 2am coming home, and I'd be afraid of waking up the neighbors. (Read: N1 street is loud)

  • @lilstahlly22 Since I updated this video last I've actually taken off the N1 Street setup, along with removing my Helix catted DP. I found a great deal on an APS 3" R1 TBE (catted), so I picked it up and swapped it onto my car. The sound of the APS is much more tolerable for a daily driver in my opinion. However, it definitely still opens up when you get on it.

  • @BBSroll Yes, a catless downpipe would produce a slightly louder sound. However, the sound will also become a bit raspier, due to having less backpressure.
