i putting a apexi n-1 single exhaust system on my 86 rx7 and im wondering if my ports will still funuction right or if i have to wire them open

 

I have an 88 RX-7 with a bonez intake and apexi N1 and the ports still function right

 

cool how loud is the n-1

 

Everything should bolt right up... see sig for my mods. The N1 is highly recommended the sound is great, it has a very nice rumble

 

I've got an N1 on my rx3... it's loud. Unpleasantly loud. Painfully loud. Pulled over 8 times in the last 9 days for it loud. I love the sound. Road race headers collecting at the axle into a 3" pipe to the N1 can. No presilencers or anything and a decent streetport and exhaust port (12a). I used to think "Hmmm... they say it's loud, I can handle loud. Loud is cool." But after 3 weeks with this exhaust, I'm either getting used to it or going deaf. At cruise out on the highway, it's loud. Through neighborhoods at a 20 mph crawl in 4th, it's loud. At 8.5k in a parking garage it's the coolest ******* sound in the world. People grab their ears, old people fall over dead, mothers run in fear toward their children, etc. And it shoots flames like a ****.
Yep, that's my exhaust. I like the N1 and would recommend the silencer.

N1 muffler doesn't muffle the sound a whole lot.

If you use the whole kit, it'll be loud, but definitely more quiet than the muffler alone (at least by 10dB).
The silencer will help, but it's still loud.

It's definitely great for exhaust flow performance.
