It's all up to your local smog laws. In Cali. Maybe, if the cop is being picky. But mostly they do t care unless the cats are changed put. I'm not sure about Nevada though. Never lived there.

On another note. I received and installed the GarageLine axle back muffler portion. I am now working on an exhaust video. But I love the sound. It's quiet but not too quiet. Nice deep tone. And the tips look great. Awesome quality. I'll post a video later tonight or tomorrow.

Just updated the First post with more videos. I added the Rear muffler axle back section from Garageline, am VERY happy with it. Hope you enjoy as much as I do.

Thanks. I know I love it. It's nice a nd quiet but still maintains the natural VA note while opening up the exhaust.

How much louder is Garageline muffler over stock? (with mid pipe, without washer mod)

Their full catback is definitely louder than stock. I don't have a decibel reader. But I can find out later today and let you know. It is less than short tails. And barely less than a stock washer mod. I would compare it to the stock car having only a top speed axle back in volume. If you have ever heard long ram intakes on this car, I would say you can hear them equally. I can hear both. And they are about equal volumewise. So nothing crazy, NO rasp at all, and deeper sounding than any other exhaust I have heard so far. Absolutely NO drone.

I hope this helps. And as I said earlier, I will try and get a db meter on it later. So we will have definitive answers about stock vs. Garageline.

For those of you who are curious.

DB levels of garageline catback exhaust:
Cold start idle-84 (5 ft from middle rear)
Warm start idle-81 (5 ft from middle rear)
Revs to 5k- 94 (5 ft from middle rear)
WOT take off- 94
Flyby WOT- 96

Just went outside and measured, They are exactly 4.5" from outer rolled wall to outer rolled wall.

If I'm not mistaken, you can request 5" tips. I know Jermaine (shop owner) has them on his Garageline catback. They are the removable tips too. So they can easily be switched out to any other tips.

Thank you for all your feedback! you are a very detailed in your descriptions! WE all appreciate the feedback. I really like the sound on the videos. Just what I am looking for. How is the interior noise? I assume from the DB readings the cabin noise is minimal?

that would be nice, a little louder and a better tone. would look good with the 5"tips also.
would love to see/hear it.

Cabin noise is very minimal. compared to stock, while cruising the difference isn't noticeable at all. cruising at 50 or 70 the car has no drone at all. I am very pleased with it. My music is no louder than it ever was when I had it stock. its almost as if the exhaust only opens up at full throttle. and even then as you can see from the DB readings, its not that much.
