ATS 3.6L with Magnaflow Axle Back

ATS 3.6L before and after installation of a Magnaflow #15196 axle back exhaust.
Details;
My ATS engine and drivetrain are stock. The before and after videos were shot after the car had sat overnight so each was a cold start. The "After" part of the video was shot in the morning in 42 degree temperatures, hence the exhaust vapor.
Filmed with a GoPro Hero Session

It sounds soooo good. Before and after

Hello
Did you tune the car after installing?
Did the check engine light appear?
Did the performance improve?
If you have the time please answer. Thank you

[@DavidBall2]

Did not tune and no check engine lights ever popped up. No felt improvement to performance.

Like to of seen a driving video. Other than that it sounds great

[@terrelldawkins3585]

How does it sound on the road when ur hitting top speed And accelerating fast and do u feel any power increase?

[@DavidBall2]

Sounds really good under acceleration but a little bit of drone under stead state cruise from 45 mph through 65 mph. The stock exhaust has been proven to flow very well so if there is any improvement in HP and Torque it's negligible.

[@calRSV4]

stock sound better and louder

Did this exhaust have bad drone on the highway?

[@DavidBall2]

No but, it did have a drone when applying very light throttle like you would do to maintain a certain speed up a slight incline. Other than that it sounds great and at highway speeds it was only slightly louder than stock. It has a very nice exhaust note under hard acceleration that's not to loud.

Lol those exhaust tip are kinda big don’t you think?
