Just had this exhaust installed on my gen this past monday. Fair warning, after install we noticed the central muffler was basically attached to my driveshaft. Took aittle but we got it right. Exhaust is cool though, you get what you pay for.

You notice it at low rpms but highway very little drone and normal street driving nothing at all really. I like it but as said I had to work with mine to get it to hang just right and line up in the back.

Fireworks nailed the sound. Its really hard to explain how much fuller and bassier the sound is, granted I'm running test pipes. Rev matched downshifts give great burbles. I would say 5-10 peak hp like every other catback. Can't say first hand though, never dynoed before. With r2c, tp and the v3, I dynoed 306hp on a dynojet sae corrected.

I have this on my 2.0T. The sound is amazing, it looks amazing, and the fit was amazing. The only think is that it is not loud enough. I'm eventually going to remove the cat, but till then thats just my opinion on the exhaust.

Fair warning, it does sound a bit hollow, like the factory system around 5000-redline.

Fitment isn't great. It needs tweaking. It's not the best built system, you definitely get what you pay for.

Had it on my car. Took a little time to get the fitment right but sounded awesome with the long tube headers I had.

I just installed it on my 2016. At this point I can't recommend it. The sound is exactly what I was looking for, but my left tail tips sit a full 1.5" lower than the right side and that looks like crap to me. Trying to figure out how to get them equal, but muffler shop says it isn't possible without a lot of fabrication. Pipes aren't bent right from the factory.

Yeah, it looks like you backed into something... :/

I have the CNT v3. I used the Torque Solutions 10mm exhaust mount and it fixed the issue.

Wish I woukd have seen those options before all the cutting/welding and spacing I had to use lol. I think it would be easier for CNT to fix the issue. It's 1 piece of pipe they have to refigure.

Had this installed this week.
I personally love it. Not 100% the sound I was going for but I'm totally happy with what I got for my money.
The exhaust shop did have to make some adjustments to it so it wouldn't rattle against the body of my car.

Definitely worth the money, and you definitely get what you paid for.

I had the V3 for about a year now. overall the exhaust is good for the money.

The resonator will crack for sure is the fitment is not perfect, after a couple of months cracks started to appear had to get it re-welded several times, very soon just going to replace the resonator with a x-pipe, definitely cheaper on the long run.
