Default To anyone who had replaced the stock exhaust with aftermarket ones.

Is there a big weight difference between the two. Which one is lighter? Stock or Aftermarket.

When I put an ABT on my '95 GTI VR6 a few years ago, the stock one is actually lighter. But it sounded so good I had to keep it.

Considering the hp gain on just an exhaust, the weight added or subtracted might make a difference.

How is the sound quality, loudness, and performance? Just ordered mine and would like your feedback.

Default LLtek exhaust feedback inside.

Check out this link for my initial review:
https://www.audiworld.com/forum/m/s4/23986.phtml

I have since fixed the moving tips issue by putting a shaft collar on the rear metal hanger. I also painted the rear muffler black.
The droning sound from 1900-2300 is not as intrusive as it was initially. Perhaps the exhaust has seasoned with age, due to carbon buildup? Or I have grown used to it? It is barely noticeable at steady interstate speeds between 2500-3900rpm. I like the sporty, throaty sound as it enhances the driving experience. When you get on it, it snarls above 4000 rpm. I would not want to go back to the coffin-like quiet of the stock system. The 2.7 biturbo has a great sounding engine note that deserves to be heard. However, this is the loudest I would want the exhaust to be.

Thanks for the review and glad to hear that the low RPM drowning is gone
