Fastest shipping ever order and every thing came the next day

N1 exhaust is good for the price i like how it sounds

Taylor G.
Love it

It's amazing for me, and the silencers come in clutch for those late nights home frok work and college. The deep tone is amazing and it really opens up when I want it to. Also quiet enough to not get pulled over for. Sometimes I wish it were just a tad louder when I'm at car meets, but it was well worth the money. The build quality and fitment was excellent and I was able to install it in under a half hour. Love it! (2021 WRX Base)

Awesome sauce

Dope exhaust. Had them on my previous car and saw this on sale so I had to buy it. Always built well and sounds amazing

N1 dual exit

Exhaust fit perfect, installed in maybe 30 minutes. Quality was is what you would expect from a mass Produced product like this. It’s quiet at idle and you can hear it under throttle but it’s not loud. No drone in cab on the highway.

Great sound and quality

Looks great and sounds great. It’s only loud and obnoxious at high RPM but otherwise it’s fairly tame. It doesn’t turn heads at idle but you can make it scream easily. The rumble sounds awesome. I’m curious how much better the titanium exhaust sounds, but I’m very happy with the stainless steel exhaust. Highway driving is a little loud but I don’t mind it. If it’s too loud for you just install the silencers that came with the exhaust.
